Umpires made Scherzer switch gloves in the third inning, then checked him again an inning laterNew York Mets ace Max Scherzer was ejected from Wednesday afternoon's game against the Los Angeles Dodgers (GameTracker) after umpires examined his glove and pitching hand following the third inning. It was the second time Scherzer was inspected in the game. The umpires had him swap out his glove for a new one an inning earlier.
The television broadcasts showed what appeared to be Scherzer yelling "it's rosin!" at home plate umpire Phil Cuzzi and crew chief Dan Bellino immediately prior to the ejection. Here are Bellino and Cuzzi inspecting Scherzer's pitching hand, Scherzer pleading his case, and then the ejection:
Pitchers ejected for foreign substances automatically receive a 10-game suspension. To be clear, it's still unknown whether Scherzer was ejected for having a foreign substance on his person, or another reason entirely. It's possible he was ejected for arguing excessively.
