A confident Ross replaces Darvish

ARLINGTON, Texas -- Robbie Ross was a lost man while he spent time with the Texas Rangers.

Now he has found himself.

The left-hander is set to replace staff ace Yu Darvish on Thursday night against Tampa Bay. Darvish went on the 15-day disabled list Wednesday with elbow trouble.

Ross is 2-4 with a 5.61 ERA in 18 games for the Rangers this season, with nine starts.

The Rangers moved him from the rotation to the bullpen, but success did not exactly follow. On June 8, he was sent down to Triple-A Round Rock, where he worked on his mechanics and confidence.

“He’s throwing the ball well and both [Round Rock pitching coach Brad Holman and minor league pitching coordinator Danny Clark] felt like he’s made progress and was ready to get another opportunity," Rangers general manager Jon Daniels said. "He would have been up in September if this had not come along.”

At Round Rock, Ross went 4-4 with a 5.10 ERA in nine games, including eight starts. He pitched deep into games, including an Aug. 2 start against Memphis in which he notched a five-hit complete game.

“It’s an opportunity and we’ll put him in there tomorrow and he feels good about himself,” Daniels said. “He’s got his confidence back and made a couple of mechanical changes, but the biggest thing is he’s got his confidence back.”
