Arizona Diamondbacks left-hander Caleb Smith has been suspended 10 games by Major League Baseball for having a foreign substance on his glove, it was announced Tuesday.
Smith, who was also fined an undisclosed amount, has appealed the penalty, allowing him to play until the appeal is heard.
Smith was ejected in the eighth inning of a game against the Philadelphia Phillies on Aug. 18. His glove was sent to New York for examination.
Smith argued and at one point had to be pulled back by some of the team's coaches following the ejection.
He is 4-8 with a 5.20 ERA and 11 strikeouts this season.
