The first major checkpoint arrived Thursday, Oct. 29, at 9:00 a.m. ET with the official launch of free agency and the opening of the five-day exclusive negotiating window. For front offices in the Bronx, Queens, and South Philly, that ticking clock presents an immediate chance to lock down key internal pieces before outside suitors enter the fold.

Here is a complete look at the pivotal dates, deadlines, and milestones defining the 2026–27 MLB offseason:

• October 29, 2026: Free agency officially begins; five-day exclusive negotiating window opens (9:00 a.m. ET)

How the Yankees, Mets, and Phillies can capitalize on the winter calendar

During the five-day quiet period, the Yankees will explore extending their own impending free agents before an open market bidding war erupts. With late-inning arms like closer David Bednar and southpaw Ryan Yarbrough slated to hit the open market, all eyes turn to general manager Brian Cashman to see if the Bronx Bombers will lock them down early or risk seeing them test the waters.

In Queens, the initial five-day window serves as an opportune moment for the Mets to sort out Bo Bichette’s contract status and gauge their infield blueprints heading into next year. Down the turnpike, the Phillies face an immediate reckoning in their infield, with longtime third baseman Alec Bohm and trade-deadline acquisition Luis Arraez hitting the open market, leaving front office to decide between aggressive reunions or allowing both to walk.

Once the market fully opens on Nov. 2, industry buzz suggests a cross-town arms race could ignite over Japanese slugger Teruaki Sato, who has reportedly drawn strong interest from both the Yankees and Mets. For the Mets, speculation also continues to swirl around ace Tarik Skubal, whose prospective arrival in the Big Apple could dominate headline space once unrestricted bidding goes live.

Come December, the Phillies could shift their strategic focus toward clearing an everyday runway for elite farmhands Aidan Miller and Justin Crawford. The Winter Meetings in particular will force Philadelphia’s brass to choose between signing veteran stopgaps or handing everyday big-league roles to their prized prospects.

Key takeaways

• MLB free agency officially launched Thursday, Oct. 29, at 9:00 a.m. ET.
• The MLB Collective Bargaining Agreement expires on December 1, 2026.
• MLB open free agency begins on November 2, 2026 (5:00 p.m. ET).

The Phillies officially hired Peter Fatse as hitting coach and Joe Cronin as assistant hitting coach, while Edwar Gonzalez will return as an assistant hitting coach, according to MLB.com’s Todd Zolecki.

The revamped trio will be tasked with revitalizing a lineup that faltered down the stretch, aiming to sharpen plate discipline, maximize run production, and steer Philadelphia back into deep postseason contention.

Alongside the hitting staff additions, the Phillies also confirmed the hiring of former New York Mets manager Carlos Mendoza, bringing him aboard in a senior advisory role on Mattingly’s staff for the upcoming campaign.

How Mattingly can maximize his new hitting trio

With Fatse stepping in as the lead voice alongside Cronin and Gonzalez, Mattingly’s primary directive will be establishing a cohesive offensive philosophy from day one of spring training.

By prioritizing clear communication on approach, pitch selection, and situational execution, Mattingly can ensure the staff delivers a singular, unified message rather than bogging hitters down with conflicting guidance.

Operationally, Mattingly has an opportunity to delegate distinct roles to suit each coach’s strengths. Fatse can quarterback game planning, mechanical adjustments, and daily matchup prep, leaving Cronin and Gonzalez to direct hands-on cage work, track advanced swing metrics, and oversee pregame routines.

Gonzalez’s familiarity with the roster provides crucial continuity, giving Mattingly an in-house bridge to help Fatse and Cronin rapidly decipher the clubhouse dynamics and individual tendencies of the Phillies’ core bats.

Key takeaways

• The Philadelphia Phillies hired Peter Fatse as hitting coach alongside Joe Cronin and Edwar Gonzalez.
• Don Mattingly was named manager of the Philadelphia Phillies for the next two years.
• Former New York Mets manager Carlos Mendoza was hired to the Philadelphia Phillies coaching staff.

Phillies president of baseball operations Dave Dombrowski announced that the club has hired Mendoza as its new third base and infield coach, as first cited by SNY.

The move marks the start of a coaching staff overhaul in Philadelphia following a disappointing postseason exit. With buzz building around the potential hiring of Don Mattingly as the Phillies’ next manager, a ripple effect of key roster decisions is expected to follow.

Among those pressing decisions is addressing impending free agents—including left-hander Luis Arraez—alongside evaluating several underperforming veterans on the 2026 roster.

Mendoza’s experience as third base coach

Before taking the top job in Queens, Mendoza spent 15 years building a reputation across Major League organizations as an elite infield coordinator and bench strategist. His coaching foundation was forged in player development, spending nearly a decade in the New York Yankees farm system as a roving defensive instructor and minor league manager.

That minor league success propelled him to the Bronx, where he served on the Yankees’ Major League staff from 2018 through 2023 as a quality control coach, infield instructor, and ultimately as Aaron Boone’s bench coach for four seasons.

Throughout his time in New York, Mendoza was directly responsible for designing daily infield routines, crafting positioning strategies, and managing in-game defensive alignments, earning league-wide respect for his tactical preparation.

Why did the Mets let Mendoza leave?

Mendoza took over as manager of the Mets prior to the 2024 season, immediately making a splash by leading the club to an unexpected NLCS run. However, after a regression during the 2025 season and a slow start in 2026, New York decided to move in a different direction midyear.

By bringing Mendoza aboard, the Phillies land a proven baseball mind with a deep divisional track record. His primary focus in Philadelphia will be sharpening the team’s infield defense and overseeing third-base coaching duties.

Key takeaways

• Carlos Mendoza was hired by the Philadelphia Phillies as third base and infield coach.
• Don Mattingly is expected to be announced as Philadelphia’s new manager.
• Mendoza served as Aaron Boone’s bench coach for four seasons with the Yankees.

Ryan Divish of The Seattle Times reports that the Yankees and Phillies are among the top suitors expected to pursue Arozarena this winter. With the All-Star outfielder set to command a lucrative contract on the open market, Seattle may be unwilling to match the high price tag required to re-sign him.

Along with New York and Philadelphia, Divish noted that the Boston Red Sox, New York Mets, and Chicago Cubs are also monitoring the market and could make a run at the Mariners star.

As the Phillies reportedly prepare to finalize Don Mattingly’s managerial contract for the upcoming seasons, anticipation is building over where Arozarena will land. Meanwhile, the Yankees may face a roster and organizational shakeup, with fans voicing frustration over the future of manager Aaron Boone and general manager Brian Cashman heading into the 2027 MLB campaign.

Arozarena’s potential impact for prospective suitors

Despite a disappointing overall season for the Mariners, Arozarena stood out as a premier offensive anchor. He paced the American League with a career-high 113 runs scored, pairing that mark with 161 hits, 26 home runs, and an impressive .281/.381/.484 slash line (.865 OPS).

Should he land in New York, Boston, Chicago, or Philadelphia, Arozarena would immediately elevate any lineup as a dynamic offensive weapon. However, potential suitors must weigh his elite bat against his defensive limitations, as advanced metrics graded him as a below-average to replacement-level defender in left field.

If any of the interested clubs decide to pull the trigger, MLB insiders project Arozarena could land a three-year deal with an average annual value (AAV) between $18 million and $22 million.

Key takeaways

• Randy Arozarena is expected to be pursued by the Yankees and Phillies in free agency.
• Boston, the New York Mets, and Chicago are also monitoring Arozarena’s free agency market.
• MLB insiders project Arozarena could command a three-year contract worth $18 million to $22 million annually.

Don Mattingly is set to be named the Phillies’ full-time manager for next season, as mentioned by MLB.com’s Todd Zolecki. The report aligns with earlier coverage from The Athletic‘s Charlotte Varnes and Matt Gelb regarding Philadelphia’s dugout leadership moving forward.

Although Philadelphia ultimately fell short in October, Mattingly was instrumental in turning the regular season around to secure a postseason berth.

Following their early playoff elimination, Mattingly declined to speculate on his future, but the front office has reportedly made up its mind regarding his continuity at the helm.

Why did the Phillies stick with Mattingly?

Initial reports suggested several candidates were in the mix for the job, including former Boston Red Sox manager Alex Cora. However, Cora’s decision to take another path altered the landscape not only for Philadelphia, but for several other interested clubs.

Ultimately, Mattingly’s regular-season performance gave the front office plenty of reason for confidence. His .590 winning percentage with the Phillies eclipsed his previous career-best mark as a skipper (.580 with the 2014 Los Angeles Dodgers).

Mattingly also posted an elite 73.3% success rate on official replay challenges, leading his staff in crucial overturns. That operational precision helped propel Philadelphia into a Wild Card spot, though their run ended with a 2-1 series loss to the Atlanta Braves.

Mattingly’s road ahead

Pending formal confirmation from the club, several major challenges await Mattingly next season. Chief among them will be evolving from a steady hand over a 162-game marathon into a sharp, high-stakes tactical decision-maker in short playoff series.

Mattingly will also need to balance workload management and rest to keep veteran stars fresh while keeping the offense consistent, specifically avoiding the extended lineup slumps that plagued the team during critical stretches.

Developing roster depth and providing young talent with meaningful high-leverage at-bats will be vital to keeping Philadelphia’s championship window open. Establishing clear tactical guidelines, a distinct team identity, and daily accountability will be essential to setting the standard across the clubhouse.

Key takeaways

• Don Mattingly is set to be named full-time manager for the Philadelphia Phillies.
• Mattingly recorded a .590 winning percentage and a 73.3% replay challenge success rate.
• Philadelphia’s season ended following a 2-1 series loss to the Atlanta Braves.

“Don Mattingly appears to have a decent or better chance to be retained as Phillies manager. Went 79-55 to get into playoffs after taking over 9-19 team and has the respect of players and front office, as I said on @MLBNetwork,” Heyman revealed on X.

As the MLB season continues through its decisive stages, many are already beginning to wonder what the future holds. Will Don Mattingly remain at the helm of the Phillies next season?

Mattingly’s big year

Despite an early exit in the Wild Card Series—losing 2-1 to the Atlanta Braves—Don Mattingly enjoyed a remarkably successful campaign after stepping in as the Phillies’ interim manager. Taking over a struggling team that opened the season at 9-19 under Rob Thomson, Mattingly completely turned Philadelphia’s fortunes around.

He led the team to a stellar 79-55 regular-season record (24 games over .500), guiding them to an 88-74 overall finish and securing a postseason berth. Though the October heartbreak remains, Mattingly’s midseason turnaround stabilized the clubhouse and proved crucial in salvaging what initially appeared to be a lost season for Philadelphia.

What is Don Mattingly’s contract situation?

Having originally signed as the bench coach prior to the 2026 season, Don Mattingly remains under contract with the Philadelphia Phillies through 2027. Following Rob Thomson’s early-season firing, Mattingly assumed duties under an “interim manager” tag.

Although his managerial title officially expired at the end of the 2026 season, his guaranteed contract ensures he will stay in the Phillies organization through 2027—either by having his interim tag removed to become the permanent manager or by transitioning back into a front-office/coaching role.

Key takeaways

• Jon Heyman reported that Don Mattingly has a strong chance of remaining Phillies manager.
• Don Mattingly led the Philadelphia Phillies to a 79-55 regular-season record after taking over.
• Don Mattingly is under contract with the Philadelphia Phillies through the 2027 season.

However, reports have surfaced linking Baltimore Orioles bench coach Donnie Ecker to the role. According to Phillies Tailgate, rumors regarding Ecker’s managerial potential date back to 2025 during his tenure with the Texas Rangers.

Ecker remains a strong candidate to take the helm in Philadelphia, though he isn’t alone on the board. The rumor mill has also connected the club to several high-profile names, including former Boston Red Sox manager Alex Cora.

Meanwhile, the front office is evaluating its current roster construction—starting with key contracts like Christopher Sanchez’s. Sanchez headlines a group of core players who are out of minor-league options and fully locked into the big-league roster for next season.

Other names on the list for the Phillies’ managerial job

Front-office executives and league insiders have consistently pointed toward proven dugout commanders who blend modern analytical backgrounds with established track records of clubhouse success.

Established leaders like former Manager of the Year Skip Schumaker and veteran manager Craig Counsell head the discussion, bringing deep experience guiding National League squads through grueling pennant races and deep October runs.

Former player and fan favorite Raul Ibanez, alongside respected baseball figures like Mark DeRosa and veteran bench coach Clayton McCullough, offer strong communication skills and a firm grasp of player development structures.

Challenges for the new Phillies’ manager

While the candidate pool is deep, the incoming manager must address recurring postseason stumbles. Over the last five seasons, the Phillies have consistently fallen short of expectations, suffering early playoff exits with the sole exception of their 2022 World Series run.

Since then, Philadelphia suffered early exits in the NLDS in 2024 and 2025, dropped the NLCS in 2023, and fell in the Wild Card round in 2026. These postseason failures stem from a pattern of late-October swoons following dominant regular seasons, a problem the next manager must solve immediately.

Key takeaways

• Donnie Ecker reportedly remains a candidate for the Philadelphia Phillies’ managerial vacancy.
• Alex Cora was among several high-profile names linked to Philadelphia’s manager search.
• The Phillies suffered early playoff exits in four of the last five seasons.

Top priority for Philadelphia: evaluating players who are out of minor-league options heading into next season. Left-hander Cristopher Sanchez highlights the group of players who cannot be sent down to the minors in 2027 without clearing waivers:

• Cristopher Sanchez
• Jonathan Bowlan
• Caleb Kilian
• Chase Shugart
• Alan Rangel
• Rafael Marchán
• Garrett Stubbs
• Derek Hill
• Kameron Misner

Meanwhile, the Phillies continue their search for a manager for next season. Despite initial speculation surrounding high-profile candidates like Alex Cora, Philadelphia will need to broaden its search and interview other candidates in the coming weeks.

Phillies players with no-trade protection

Several core pillars of the roster hold trade protection for next season, a key variable for the front office as it maps out future lineups. Anchoring that list are franchise cornerstones Bryce Harper and Trea Turner:

• Bryce Harper: Full No-Trade Clause
• Trea Turner: Full No-Trade Clause
• Kyle Schwarber: 10-and-5 Rights
• Zack Wheeler: 10-and-5 Rights
• Aaron Nola: 10-and-5 Rights
• J.T. Realmuto: 10-and-5 Rights

With these roster parameters locked in, the Phillies enter the offseason facing a crucial winter as they look to bolster key areas for another postseason push, after a struggling season.

Key takeaways

• Cristopher Sanchez highlights Philadelphia players who have no minor-league options left for 2027.
• Alex Cora was mentioned among initial managerial candidates for the Phillies’ vacancy.
• Bryce Harper and Trea Turner hold full no-trade protection for next season.

The position was offered by Dave Dombrowski in April, when Cora also turned it down, saying that he wanted to spend time with his family. This is therefore the second time that both sides have failed to connect.

Clearly, the Phillies’ intentions to bring in this experienced manager are evident, but apparently, the timing is not right. Now it will be a matter of seeing which name they ultimately choose to take charge of a team looking to get back into the MLB spotlight.

The Cora-Dombrowski story

Under the executive leadership of President of Baseball Operations Dave Dombrowski and the dugout guidance of Alex Cora, the 2018 Boston Red Sox put together one of the most dominant seasons in Major League Baseball history. Built on Dombrowski’s aggressive roster moves—such as signing marquee free agent J.D. Martinez and trading for key contributors like Chris Sale and Nathan Eovaldi—the team won a franchise-record 108 regular-season games.

Guided by Cora’s tactical instincts and culture, Boston blazed through the postseason with an 11-3 record, defeating the Yankees, Astros, and ultimately the Los Angeles Dodgers in five games to capture the ninth World Series championship in franchise history.

What will happen with the Phillies’ managerial position next season?

Following the Philadelphia Phillies’ early October exit from the postseason, speculation surrounding the team’s managerial search and bench coaching staff has reached a fever pitch. Don Mattingly spoke about his future after postseason elimination, making it clear that he is not concerned about his situation heading into what comes next.

As front office executive Dave Dombrowski evaluates the roster and coaching hierarchy heading into the offseason, the organization must decide whether to promote internally, stick with continuity, or seek a fresh voice to guide the franchise next season.

Key takeaways

• Alex Cora decided to take the 2027 MLB season off.
• Dave Dombrowski first offered the managerial position to Alex Cora in April.
• Don Mattingly’s not concerned about his situation.

Philadelphia’s list of pending free agents is extensive, headlined by position players Arraez, Adolis Garcia, Alec Bohm, and Edmundo Sosa. On the pitching side, key arm decisions include Jose Alvarado, Brooks Raley, Tim Mayza, and Nestor Cortes.

The front office faces an immediate dilemma with everyday regulars like Garcia, Bohm, and Arraez. Each played significant roles during the regular season, leaving the organization to weigh the financial cost of retention against the need for structural changes.

Compounding the player movements, the coaching staff’s future remains unresolved. Interim manager Don Mattingly addressed his status immediately after Philadelphia’s Wild Card round loss to the Atlanta Braves, leaving the dugout leadership up in the air.

Which pending free agents could Dave Dombrowski target for retention?

As president of baseball operations Dave Dombrowski evaluates the Phillies open-market departures, two priority names stand out as potential targets for return.

Arraez and Bohm represent the most logical extensions. For Arraez, contract negotiations will depend on his valuation, but his elite contact bat makes him a prime candidate for a qualifying offer or a multi-year deal.

Meanwhile, Bohm presents a strategic choice. Philadelphia must decide whether to secure him on a long-term contract extension before he hits free agency or test the trade market to recoup value before his market opens.

Key takeaways

• Another early exit from the MLB postseason sparked widespread speculation regarding Philadelphia’s roster.
• Pending free agents include position players Luis Arraez, Adolis García, Alec Bohm, and Edmundo Sosa.
• Dave Dombrowski must evaluate open-market departures to determine which priority names return.

“It’s not the time to talk about it… I’m not concerned about myself in this situation,” Mattingly said during his postgame press conference. “I want the Phillies to do what they need to do to set themselves up for success. My staff doesn’t really matter at this time.”

A return to the Phillies’ bench next season remains plausible, despite reports linking Mattingly to the vacant New York Mets managerial job. After taking over a squad mired in an 9-19 slump, he orchestrated a dramatic midseason turnaround to finish the regular season at 88-74.

With key stars like Trea Turner shouldering accountability for a cold postseason offense, Philadelphia now shifts its focus to an offseason of reflection ahead of the 2027 campaign.

Phillies’ late-season stumble

Despite their impressive regular-season recovery, the Phillies will look back on a late September stumble that drained their momentum right before the October push.

A late-season injury to Jesus Luzardo forced Philadelphia into multiple bullpen games across the final three rotation turns in September. Compounding the issue, a tight battle for playoff seeding forced Mattingly to start ace Zack Wheeler on the final day of the regular season against Tampa Bay, burning him for the Wild Card opener and upending the team’s postseason rotation setup.

Between losing Brad Keller midseason and a taxing year for high-leverage lefty Jose Alvarado, the bullpen was stretched thin. Key late-inning options like Jhoan Duran were relied upon earlier in games, leaving few dependable arms to close out high-stakes contests.

Key takeaways

• Don Mattingly addressed his future following Philadelphia’s 6-2 Game 3 loss to Atlanta.
• He orchestrated a dramatic midseason turnaround to finish the regular season at 88-74.
• A late-season injury to Jesus Luzardo forced Philadelphia into multiple bullpen games.
