Lewis to get one more rehab start

OAKLAND -- The Rangers have decided to keep right-hander Colby Lewis on medical rehabilitation assignment and he will pitch for Triple-A Round Rock on Thursday against Salt Lake.

Lewis pitched for Double-A Frisco on Saturday and allowed two runs in five innings. He allowed six hits and one walk while striking out three. He threw 86 pitches and will shoot for 100 on Thursday against Salt Lake City.

"With each outing, he says he feels better health-wise and stuff-wise, but we still feel it is most prudent to make sure he is 100 percent," assistant general manager Thad Levine said. "He said there is a real benefit from having him make another start."

Lewis had surgery on July 27, 2012, to repair a torn flexor tendon in his right elbow. His rehab assignment ends on Aug 15, so he has time to make two more starts. After that, the Rangers will have to decide whether to activate him. Right now there is no room in the rotation, unless Alexi Ogando is moved to the bullpen or Martin Perez is sent to Triple-A.

Neil Ramirez waits to learn trade fate

FRISCO -- Matt Garza has made three starts for the Rangers since he was acquired on July 22, but there's still a player to be named that the Cubs will receive as part of the trade. Double-A Frisco pitcher Neil Ramirez could be that player, or the Rangers could send two other players to Chicago.

"You hear stuff from the Internet, but I'm just trying to get healthy," Ramirez said. "Whatever happens, happens. It's one of those things you can't control so there's no use in worrying about it. Either way, I just got to get healthy, go back out there and compete again."

Ramirez was placed on the disabled list on July 24, retroactive to July 21, with a right shoulder injury. The 14th best prospect in the club's farm system, according to MLB.com, has had shoulder problems during his six years in the Minors.

"It's kind of been from throwing and a combination of some other things," Ramirez said on the injury. "For the sake of not really wanting to get into that, it was just an off-the-field thing. It wasn't anything serious. I'm just glad to get back out there now."

The Rangers' supplemental first-round pick in the 2007 First-Year Player Draft threw a 35-pitch bullpen session this week and plans to have another session Sunday, throwing around 45-50 pitches. If all goes well, Ramirez thinks he'll be ready to return.

"I'm just taking it day by day, but it's definitely feeling a lot better," Ramirez said. "I thought the effort level and intensity was good. I was able to make all my pitches with no problems and felt comfortable."

Worth noting

• Ian Kinsler's home run on Saturday gave him 10 for the season. He is the seventh player in club history with at least seven seasons of 10 home runs or more.

• After going 1-for-8 on Saturday, the Rangers are hitting .244 with runners in scoring position on the season, on pace for the club's lowest mark since posting a .227 average with RISP in 1992.

• The Angels are scheduled to pitch Jerome Williams, Garrett Richards and Tommy Hanson during the three-game series against the Rangers that starts on Monday in Anaheim. The Rangers miss Jered Weaver and C.J. Wilson.
