"It can turn good or bad now in the next day or two," manager Buck Showalter said. "Because taking the top of it off is not good initially for pitching, but to heal now it is good. So the next couple days ... we got an extra day to play with [in Monday's off-day] if we do push him back."
Gonzalez, who had the area bandaged on Saturday afternoon, could have his bullpen session pushed back as well, although that wouldn't be as big of an issue given that the team could cover it up for the shorter side. Gonzalez said Friday night that the blister, which is pretty deep, particularly bothered him while throwing his curveball.
"It all started in the fourth inning, and it just got worse and worse," Gonzalez said of the blister hampering his grip. "It was a little tougher at the end, but the good thing was my command was there. I was happy with that."
