"It was just an off day," Scheppers said. "I just didn't have it. Poor command of everything."
Scheppers was charged with two runs, raising his ERA from 1.11 to 1.55. Scheppers said before the game he needed an extra day off Saturday, but there was nothing wrong physically.
"He was a little bit off," Geovany Soto said. "We were trying to attack the strike zone."
Scheppers has appeared in 39 games, tied for the third-most relief appearances in the American League. Prior to his three days off, Scheppers had pitched seven times in a stretch of 11 games.
"He has been taking on a huge workload and we decided to back off him," manager Ron Washington said before the game. "I certainly don't want him trying to battle through something and cost us more time. I'd rather give him time down now."
