"With the way I improved today, if we can keep it here and get it a little better, I feel good to go," Wieters said of the right bicep soreness that kept him out of Friday's lineup and started during an at-bat on Thursday.
"I think the big thing is miss one [more] game here as opposed to having that doubt in your mind where it might set you back two or three weeks."
Wieters did not swing on Friday, just getting treatment, but said he would test his swing during Saturday's pregame batting practice. He does not feel the soreness when throwing or catching, just when extending his left-handed swing.
"If I wanted to really push the envelope, I could probably play him," manager Buck Showalter said. "I don't think anybody wants to think about not having him right physically, especially 60-something games left. So, [we will] back off him."
Showalter wasn't willing to commit to definitely starting Wieters on Sunday, and Taylor Teagarden made his second consecutive start Saturday in Wieters' place. A two-time All-Star, Wieters is hitting .238 with 12 homers and 46 RBIs in 90 games, but has struggled recently. He is batting .197 (14-for-71) in 19 games in July with three extra-base hits.
