Peralta came out of the pen with plans of starting the eighth inning to protect the Rays' 5-4 lead. That never happened. The umpires convened at the mound and started giving his glove the once over. One of the umps confiscated said glove and carried it off the field. And Peralta was ejected.
The Washington Post's Adam Kilgore tweeted out the news:
Press box announcement on Joel Peralta: Ejected for having a "foreign substance on or in his fielding glove."— Adam Kilgore (@AdamKilgoreWP) June 19, 2012
Jake McGee handled Tampa Bay's pitching duties in the eighth in his place, and he did so in perfect fashion. McGee did not allow a hit or walk, and the Rays held their lead for the 5-4 win.
