Seattle Mariners pitcher Hector Santiago was ejected in the fifth inning of Sunday's game against the Chicago White Sox after umpires inspected his glove.
Santiago, 33, was pulled from the game after giving up two walks and two hits in the inning.
Per the league's new rule on inspecting pitchers for foreign substances, Santiago handed his glove over to be inspected by home plate umpire Phil Cuzzi, who ejected him moments later. From replays, it looked like the umpires were checking the inside of Santiago's glove.
The glove could be seen being wrapped up by the authenticator to be further inspected later under the new rule that went into effect Monday.
