Ogando is scheduled to start again Sept. 10 in Arlington against the Oakland Athletics. The club also will use the off-days to give Matt Harrison more time after his start Sunday. He won't pitch again until Sept. 13.
Rangers manager Ron Washington said Ogando needs more of a mental break at this time, though he acknowledges that Ogando is throwing more innings than he has in his career. Ogando's velocity has been fine, but his command has been wayward at times.
"We figured we'd give him a rest and maybe he can catch his second wind," Washington said.
Ogando has pitched 154 innings this season. He is 12-7 with a 3.68 ERA but 1-2 with an 8.34 ERA (22 2/3 innings) in his last five starts with 15 strikeouts and eight walks. He pitched 72 1/3 innings in the majors and minors last year, so he's adjusting to throwing that many innings. But unlike Harrison, Ogando's velocity hasn't really gone down much to indicate he was fatigued physically.
"The velocity is fine and it's coming out of his hands fine," Washington said. "It's just the adjustment part of it. When you get to the adjustment part of it out there when things are not happening like you want them to happen, that's mental."
