ARLINGTON -- Manager Ron Washington was impressed with Martin Perez's first big league start Saturday but left open the possibility that Derek Holland could retake his spot in the Rangers rotation.

Holland will make his second rehab start with Triple-A Round Rock on Monday. His pitch count is set at about 75-80 pitches. The current plan is to have Holland make a third rehab start and take the mound for the Rangers after the All-Star break. But, with an off-day coming Monday, Yu Darvish's next start could be moved up to Friday's series opener against the Twins, which would allow Holland to possibly start Saturday.

"There's a chance. You can't rule it out," Washington said. "We'll have some of our big eyes down there. If they feel like maybe we need to let him have the start, that might be the way it'll be. But that's not a decision we've made."

If Holland does make his a third start with Round Rock, Washington will choose between Perez and Justin Grimm for the start against the Twins. Perez gave up two runs on six hits in 5 1/3 innings in Saturday's win over the A's, while Grimm is 1-1 with an 11.57 ERA in two starts.

Roy Oswalt will pitch Tuesday's series opener against the White Sox, followed by Scott Feldman on Wednesday and Matt Harrison on Thursday. If Holland pitches well Monday in Round Rock, he could rejoin the Rangers on Friday when they return to Arlington.

"That could change. Write it in pencil so you can erase it," Washington said. "It's an option, that's all it is."

Worth noting

• Scott Feldman hosted the first annual Faces of Freedom Softball Game at the Ballpark in Arlington on Sunday afternoon. The Warrior Transition Brigade, a group of soldiers who combined for 32 deployments and four Purple Hearts, took on the Texas Rangers Legacy Alumni, a team of former Rangers.

"It's something my wife and I have been doing, starting last year," Feldman said. "It's just a way to get them out here and enjoy some baseball."

• Josh Hamilton has a bruise under his right armpit from when he was hit by Duane Below in the sixth inning of Wednesday's win over the Tigers.

"I like big bruises," Hamilton said. "It just tightened up. You don't really notice it until you get in the game and really take a hack."

• Ron Washington said that he's hoping injured pitchers Koji Uehara (strained lat) and Alexi Ogando (strained groin) will have bullpen sessions when the Rangers travel to Chicago for a three-game series against the White Sox that begins Tuesday. Neftali Feliz (elbow inflammation) said Saturday he plans on doing the same.

• Washington on Mitch Moreland, who was placed on the 15-day DL with a strained hamstring June 22: "He's still getting treatment and in the pool, strengthening up his legs. We're talking about a hamstring on legs like that. It's not like talking about hamstrings on my legs."
