Gentry bats second as Rangers shuffle order

ARLINGTON -- Craig Gentry made his seventh career start in the second spot of the order Sunday against the O's. He started in center field with Leonys Martin in right and Nelson Cruz as the designated hitter. Rangers manager Ron Washington planned to place Cruz in the designated hitter position Sunday, giving the club a better look defensively in the outfield.

In a perfect world, Elvis Andrus would hit second in the Rangers' order. Washington has recently shuffled in different players in attempt to take pressure off Andrus in that spot. Andrus went 1-for-4 Saturday, dropping to 4-for-25 in his last seven games.

"I want Elvis to give me a spark in that spot," Washington said. "It just gives him a little more time to relax. I put Gentry in there, and I can use him to do different things if I had to."

Harrison on track to move forward in rehab

ARLINGTON -- Matt Harrison could possibly throw his final bullpen session Monday before taking the next step toward rejoining the Rangers. The left-hander expects to throw 60-65 pitches. If everything goes well, Harrison said he'd throw a batting-practice session Wednesday.

"I'm probably not going to throw as many bullpens as I thought I would," Harrison said.

He said he threw 40-45 pitches in his previous bullpen session, and he'll increase the workload by 20 pitches Monday.

Harrison underwent a second operation in May to address a herniated disk in his lower back. Harrison said earlier this month he looked to return at the end of August. It appears he is ahead of his projected target.

Texas expects to have Ogando start Tuesday

ARLINGTON -- Unless something changes in the next 48 hours, Rangers manager Ron Washington will activate Alexi Ogando off the disabled list to start Tuesday against the Yankees.

Washington said Ogando could probably throw 100 pitches, given he threw 80 pitches in his final rehab start on Thursday with Triple-A Round Rock.

"He could probably add 20 to it, which which what we wanted to make certain when he came up here; we didn't have to put him on a strict pitch count," Washington said.

Washington said the club will closely watch Ogando on the mound and not attempt to extract more than the pitcher can give.

"If we think he did well after five, that's it," Washington said. "If we think he did well after six, that's it. We won't try to get more."

Thursday's starter is "TBA," which could stand for to be announced or to be acquired. The Rangers have attempted to acquire Matt Garza throughout the weekend and had a scout watch Jake Peavy pitch for the White Sox Saturday against the Braves. Cubs manager Dale Sveum told reporters Sunday he's confident Garza will start for the Cubs Monday. In that situation, Garza wouldn't be available to pitch if acquired after his start to pitch Thursday.

Washington said Ross Wolf remains an option to start Thursday. He allowed seven runs on nine hits in two innings Saturday against the O's.

No timetable for Tepesch to throw 'pen session

ARLINGTON -- Nick Tepesch said Sunday he feels good throwing from 120 feet, but there isn't a timetable for a bullpen session. Tepesch has thrown all week.

Tepesch was placed on the 15-day disabled list with right elbow inflammation on July 7. He's eligible to be reinstated Sunday, which certainly won't happen.

"Any time you're on the [disabled list], it's frustrating, but it's feeling a lot better," Tepesch said. "I'm getting closer to where I need to be."

Tepesch is 4-6 with a 4.85 ERA in 16 starts this season.

Worth noting

• Rangers manager Ron Washington said Lance Berkman could participate in batting practice on the field Monday. He's on the 15-day disabled list with left hip inflammation.

• The Rangers' bullpen has thrown 17 consecutive shutout frames entering Sunday's game against the Orioles. Texas' relief corps threw seven scoreless innings Saturday; it has complied a Major League-best 2.00 ERA since June 7.
