Seattle Mariners pitcher Héctor Santiago has been suspended for 10 games after officials found a foreign substance on his glove during Sunday's game against the Chicago White Sox, the MLB confirmed to USA Today.

Santiago is the first player to be suspended for using an illicit substance since the MLB's crackdown on the practice of using sticky substances to improve pitchers' grip.

He was ejected from the game on Sunday after umpires checked his glove.

Along with his suspension, Santiago was also fined an undisclosed amount, MLB reporter Mark Feinsand said on Twitter. Santiago has appealed the suspension.
