BALTIMORE -- Matt Wieters was not in Friday's starting lineup as the Orioles' catcher is dealing with some right biceps soreness that he felt during his first at-bat Thursday afternoon.
"We want to make sure we can get that full-go," Wieters said of the injury, which only bothers him on his left-handed swing. "We think if we get a day off today and we'll be good to go [on Saturday]. We don't want a one-day tightness to turn into something more."
Orioles manager Buck Showalter was optimistic that it was just some cramping from Thursday's game, which was played in temperatures that hovered in the upper 90s, and dismissed any notion that it came at an already opportune time to give Wieters a breather.
"No such thing as a good time to not have Matt in the lineup," Showalter said of his starting catcher, who is in a 1-for-30 slump. "We don't look at it as the 's' word. We look at it as not currently performing with the level he has spoiled us with."
Wieters spent the afternoon going over video and speaking with roving hitting coach Terry Crowley, who previously served as the Orioles hitting coach at the Major League level. He said Friday he hoped the day off would help get him healthy and back on track offensively.
"[I've] been watching video all year, just trying to get that swing locked in," Wieters said. "Hopefully, today I can just get more [away from the] mental strain and try to figure out the swing a little bit and be ready to go."
A two-time All-Star, Wieters is hitting .238 with 12 homers and 46 RBIs in 90 games. He is batting .197 (14-for-71) in 19 games in July with three extra-base hits. Taylor Teagarden got the start in Wieters' place Friday night, working with lefty sinkerballer Zach Britton for the second consecutive outing.
