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, who told reporters on Sunday that it was only "sweat and rosin" on his hands, is appealing the suspension.

In a statement about its recent crackdown on June 15, the MLB said it would suspend players for 10 games if officials found they had applied "a foreign substance of any kind to the ball."

Rosin bags, which are used to keep pitchers' hands dry, is allowed per the rules, but combining it with anything else is prohibited, the MLB said.
