MLB suspended Caleb Smith of the Diamondbacks after his confiscated glove was found to be contaminated with a foreign substance. Smith was ejected from the game for arguing about the confiscation.

“For me, of course I’m frustrated,” Diamondbacks manager Torey Lovullo said. “I’m hurt when the player hurts. That’s how I wear it. I’m emotionally attached to these guys. With Caleb, I think he’s extremely frustrated. He’s frustrated because he’s been accused of some wrongdoing that he thinks is not justified. That’s why I think he wants to appeal. He wants to be heard. He wants to get his story out there.”

There is no mention of what was on the glove. Maybe that will come out at the appeal.
