Foreign Substance in Mike Fiers Glove Post No Hitter?


Literally minutes after Mike Fiers completed his no hitter in Houston vs the Dodgers, twitter started chattering. Many photos like this one started surfacing, showing a possible foreign substance in his glove post no hitter. The quality isn’t the best, but I’ve never seen a glove sweat, nor a glove with a patent leather inner thumb. So you be the judge. What’s this?!?!
