Tepesch says knee OK, but next start not assured

ARLINGTON -- Nick Tepesch said that his left knee is fine, one day after discomfort forced an early exit from Saturday's start.

Tepesch is planning to make his next start, which would fall on Friday against the Indians, but manager Ron Washington is not ready to say if Tepesch will definitely do so.

"We'll see how things go," Washington said. "Today he feels good."

The Rangers have Yu Darvish, Nick Martinez and Colby Lewis pitching during the three-game series against the Yankees. Friday's starter is unknown. It could be Tepesch, Miles Mikolas or Jerome Williams.

Williams allowed one run in six innings in a victory over the Athletics on Friday but has not been scheduled for another start. He could be available out of the bullpen as soon as Monday.

In other pitching news, the Rangers have decided that Derek Holland will begin his rehab assignment on Wednesday, pitching two innings for Double-A Frisco. The Rangers made the decision after Holland went through another fielding drill on Sunday.

Holland, who is recovering from offseason surgery, did not look completely smooth in his fielding, but the Rangers decided to let him begin his rehab stint.

"I'm excited," Holland said. "I want to be out there playing. No matter how the season is going, if we go down, I want to go down with them. I just want to be a part of the team."

Worth noting

• The Indians are expected to pitch Justin Masterson, Danny Salazar and Trevor Bauer during their three-game series against the Rangers next weekend. The Rangers then go to Chicago for a three-game series against the White Sox and at this point are expected to face Hector Noesi, John Danks and Chris Sale.

• The Rangers have a three-man bench, and that forced Washington to use Leonys Martin in the lineup on Sunday against left-hander Scott Kazmir. Martin entered the game with four hits in his last 23 at-bats against left-handers. Said Washington: "I can't say it has been all right. Of course he can do better."

• Outfielder Jake Smolinski, who is on the disabled list with a bruised left foot, is still not able to take batting practice or run at full speed.
