The Houston Astros are aiming to capitalize on the free agents available in the MLB market, and one of their targets was a pitcher who recently played for the Arizona Diamondbacks and, two years ago, for the New York Yankees. After nearly a decade as a professional, he holds a career 4.20 ERA.
The first to report the surprising signing of Miguel Castro by the Astros was Jon Heyman. Contract details were later shared by Ari Alexander, who revealed that the Puerto Rican right-hander signed a minor league deal with an invitation to spring training. If he makes it to the MLB roster, he could secure $1.5 million.
Miguel Castro set a personal record for relief appearances with the Diamondbacks, pitching in 75 games during the 2023 season. This surpassed his previous high of 69 games with the Mets in 2021. While he posted a 4.31 ERA in 2023, his performance in 2024 has been less consistent, with an 11-game stint resulting in a career-worst 5.93 ERA.
Castro’s time with the Yankees in 2022 was short-lived, appearing in 34 games and pitching just 29 innings. During that span, he allowed 27 hits, 16 runs, 13 RBIs, and two home runs, finishing with a 4.03 ERA—his third-worst mark over the past four seasons.
Playoff and World Series Experience
Despite not being currently signed to any team and exploring free agency, Castro brings valuable postseason experience. He pitched in eight playoff games with the Diamondbacks in 2023, including three appearances in the World Series. He also has playoff experience from his time with the Yankees.
Castro’s Latest MLB Salary
It remains uncertain what Castro’s salary would be if he signs with the Astros or another team. His most recent contract with the Diamondbacks, a one-year deal covering the 2023 and 2024 seasons, paid him $3.5 million—the highest annual salary of his career to date.
