Major League Baseball umpires have a multifaceted and demanding role during a baseball game. In addition to enforcing the rules of the game, they are also responsible for monitoring the pitchers closely to ensure that they are not violating any regulations. This is no small task, as pitchers are constantly evolving their strategies and techniques in an effort to gain an advantage over hitters.

One of the most important duties of an MLB umpire is to call balls and strikes accurately. This can be a challenging task, as the strike zone is relatively small and the pitcher's release point can vary from pitch to pitch. Umpires must also be aware of the rules governing pitching motions, such as the balk rule and the illegal pitch rule.

If a pitcher is caught violating the rules, they can be ejected from the game and suspended for multiple games. This can have a devastating impact on a team, especially if the ejected pitcher is a key starter or reliever.

What are MLB umpires looking for when they check pitchers' hands after the inning is over?

Umpires check pitchers' hands for illegal substances that could be used on the ball to gain an advantage during the game. In 2021 and 2022 it was revealed that some MLB pitchers used a resin-based substance called Spider Tack during games.

Since 2021 umpires are making random 'visits' to the pitching mound to check pitchers' hands, even umpires check the insides of pitchers' pants for illegal substances. In addition to checking pitchers' hands, MLB umpires are also authorized to check their hats, gloves and belts.

Other illegal substances used by pitchers:
- Pine Tar
- Sunscreen

The MLB said on the matter "...a uniform standard for the consistent application of the rules, including regular checks of all pitchers regardless of whether an opposing club's manager makes a request..." This measure not only applies to the MLB but also to the minor leagues.

MLB umpires play an important role in ensuring that the game of baseball is played fairly and safely. By enforcing the rules and maintaining order on the field, umpires help to create a positive experience for players, coaches, and fans alike.

What happens if the umpire finds an illegal substance on the pitchers hands?

If an umpire finds evidence of a foreign substance on a pitcher's hand, the pitcher will be ejected from the game and suspended for 10 games. This is a severe penalty, but MLB is committed to cracking down on the use of foreign substances in order to create a more fair and competitive environment for players and fans.

What are some of the challenges that MLB umpires face when checking pitchers' hands for foreign substances?

One of the biggest challenges that MLB umpires face when checking pitchers' hands for foreign substances is that the substances can be very difficult to detect. Another challenge that umpires face is that pitchers are becoming increasingly sophisticated in their methods of applying foreign substances. Pitchers are now using a variety of different substances.
