Washington encouraged by Perez's debut

ARLINGTON -- For the second time this month, a Rangers pitcher made his Major League debut.

With the Rangers holding an 11-5 lead over the Tigers in the eighth inning Wednesday, Martin Perez took the mound for the first time as a big leaguer. In his first Major league outing, he gave up four runs, one of them earned, on two hits, striking out one and walking one. He pitched 2/3 innings, throwing 20 pitches, 11 of them for strikes.

"We know he's got good stuff," manager Ron Washington said. "He just has to learn how to use it at the big league level. Those hitters walking up there, I know he's never seen them in Triple-A. If you leave something in the wrong spot here, you're going to get hurt."

After giving up an RBI single to Austin Jackson, Perez struck out Quintin Berry swinging for the second out of the inning. He walked Miguel Cabrera before Prince Fielder hit a sharp groundball to Ian Kinsler, who missed Perez with his throw as Perez was covering first base.

Perez was then replaced by Mike Adams, who gave up a pair of RBI singles. Both runs were charged to Perez, although they were unearned.

"It was really important for him to go out there and get a feel in the big stadium facing Major League hitters," Washington said. "He's just got to command his fastball and trust his stuff and trust the defense behind him. That's about it."

Holland pleased with first rehab start

ARLINGTON -- Of the five Rangers pitchers on the disabled list, Derek Holland may be the one to come back first.

Holland threw three innings in his first rehab start with Triple-A Round Rock last night, giving up one run, walking two and striking out one. He threw 39 pitches, 24 of them for strikes and surrendered a solo home run in the third inning.

Before being placed on the 15-day disabled list with left elbow fatigue June 7, Holland was 5-4 with a 5.10 ERA. He was also suffering from a stomach virus.

"I thought it was very productive," Holland said of his rehab start. "I threw a lot of strikes. I did everything to keep my team in the game. I thought I did a pretty good job of keeping my pitch count down."

Holland threw about 15 pitches in the bullpen after his outing Wednesday and will start again in Round Rock Monday. A decision on whether to active him will be made following that outing. The current plan is to have Holland make three starts with the Express.

"It just depends on how he does and what the need is at the time," manager Ron Washington said. "When he gets his last one, it'll be a total blowout. We'll just let him go as long as he can go."

Colby Lewis (forearm tightness), Alexi Ogando (strained groin), Koji Uehara (strained lat), and Neftali Feliz (elbow inflammation) are not expected back until after the All-Star break. But if Holland returns after his outing Monday, he could start against the Twins in the Rangers' final series before the break.

"I'm not trying to rush anything," Holland said. "I'm doing my part to get myself ready. I want to be back here and finish strong to help the team get to where we want it to go. We're really happy that, despite what's going with injuries, everyone's been stepping up and doing their part."

Washington waiting to decide Saturday's starter

ARLINGTON -- The Rangers have yet to decided who will start Saturday against the Athletics, although a decision should be made by Friday.

Saturday's game would mark Justin Grimm's spot in the rotation. The 23-year-old right-hander won his Major League debut against the Astros June 16 before allowing six runs on eight hits in one inning of work during Monday's loss to the Tigers. Grimm and Martin Perez, who was called up from Triple-A Round Rock Tuesday, are among the candidates to start Saturday.

"You'll know by tomorrow," manager Ron Washington said. "I'll know by tonight."

"They haven't told me that much," Grimm said. "I'll just take it day to day and try not to worry about it much. I'm just going to work and hope that I start Saturday."

Perez made his Major League debut Wednesday, giving up two hits and four runs, only one earned, in 2/3 innings. He and Grimm were both available out of the bullpen, although Perez might get a day off Thursday.

"I don't know if we'll try to use Perez back-to-back," Washington said. "But Grimm certainly is [available]. I'm not saying Perez won't be, but with that kid, we might be a little more cautious."

Washington added that his team's off day Monday would not affect the rotation.

"We're not skipping anybody," he said. "We're going to give everybody their rest, which they need."

Prospect Loux suffers first loss in last 11 months

ARLINGTON -- Rangers' No. 18 prospect Barret Loux, coming off his worst outing of the year, is not frustrated with himself.

The 23-year-old right-hander suffered his first loss in 11 months Friday. Loux was 11-0 with a 3.03 ERA in his first 13 starts with Double-A Frisco this year before surrendering nine runs on eight hits in three innings in his last start. He also balked and committed an error in the 13-7 defeat.

"I just didn't make the big pitch very well," Loux said. "The difference between a good game and a bad one is about two or three pitches. That night, it just didn't work out."

Even after that outing, Loux is still tied for the most wins this year by a Minor League pitcher with Reno's Trevor Bauer. Like Bauer, Loux was a first-round pick by the Diamondbacks, who took Loux with the sixth overall pick in 2010 and selected Bauer with the No. 3 overall pick in 2011.

"I feel good. I feel fortunate to have 11 wins, our guys have scored a lot," Loux said. "My goal this year is to stay healthy and to give my team a chance to win every time I go out."

Worth noting

• Triple-A Round Rock outfielder Joey Butler was selected to the 2012 Pacific Coast League All-Star Team Thursday. Butler, the Express' only All-Star, is batting .285 with 11 home runs, 40 RBIs, a team-high 57 runs and a PCL-best 49 walks.

• Roy Oswalt became the first Rangers pitcher since Nellie Briles in 1977 to allow 13 hits and be credited with a win Wednesday. The Tigers had 17 hits for the game, none of them home runs, marking the first time this season the Rangers allowed at least 17 hits without giving up a homer this year.

• At 47-29, the Rangers have posted the team's best 76-game record in team history. The Rangers, who have won six straight series, are a season-high 18 games above .500.

• High-A Myrtle Beach pitcher Kyle Hendricks turned in the team's first nine-inning complete game since May 17, 2007 in Wednesday's 5-1 win over Lynchburg.
