ARLINGTON -- For the first time this year, Martin Perez will be coming out of the bullpen. And he couldn't be happier.

"Of course I am very happy," Perez said. "I've been working hard and it's finally paid off for me. I'm here to help the team as much as I can and stay here."

Perez was called up from Triple-A Round Rock on Tuesday, replacing an injured Colby Lewis on the Rangers' roster. With Lewis on the 15-day disabled list with tendinitis in his right forearm, Scott Feldman returns to the Rangers' rotation. Perez takes over for Feldman as the team's long reliever, but could go into the rotation on Saturday.

"I was trying to call my fans in Venezuela over there, but it was late," Perez said. "After that, I called my wife and she answered. Then I called my agent, who has done a lot for me."

Perez, who last made an appearance as a reliever in 2011 with Double-A Frisco, said he won't change his routine much despite the transition from the rotation to the bullpen.

In his last two starts, Perez, the Rangers' No. 2 prospect, according to, went 2-0 with a 1.13 ERA. He was 3-5 with a 5.40 ERA in his previous 13 starts this season.

"The thing that I changed is my long toss," Perez said. "I've also been doing extra in the bullpen, getting control of my pitches is what's been helping out."

Lowe earns respect with extra inning

ARLINGTON -- Rangers manager Ron Washington considered using Scott Feldman in the ninth inning during Monday's 8-2 loss to the Tigers. Mark Lowe told him that wasn't necessary.

Lowe had already pitched two innings, but was willing to pitch the ninth. That kept Washington from using Feldman or Alberto Gonzalez, the Rangers' utility infielder who was going to pitch if Lowe ran into trouble. Washington did not want to burn Feldman, who is scheduled to start on Thursday against the Athletics.

Lowe prevented that and has now pitched nine scoreless innings over his last six outings.

"He earned a lot of respect from his teammates," Washington said. "But he already had a lot of respect. But that's what our guys do. He knew we needed him to pick us up and he picked us up."

Feldman was in the bullpen because the Rangers replaced him in the rotation with rookie starter Justin Grimm. Now, Feldman is going back into the rotation to replace Colby Lewis, who was placed on the disabled list with tendinitis in his right forearm. Feldman is 1-6 with a 6.43 ERA in eight starts for the Rangers this season.

"I'm not worried about his record; he saved us a lot," Washington said. "I can't say enough about what Feldman has done for us."

Ramirez settles in during first Frisco start

FRISCO -- Neil Ramirez admitted that he was disappointed about being moved from Triple-A Round Rock to Double-A Frisco.

"You're always a little upset when you get moved down," Ramirez said. "It's kind of a bummer. I try to stay positive as much as I can."

Ramirez was 6-8 with a 7.66 ERA in 15 starts for Round Rock. In his first start with Frisco, Jonathan Villar hit the second pitch he threw over the right-field fence. But Ramirez bounced back, not allowing another run and giving up just one more hit in six innings during the 4-1 win, picking up his first victory in more than three weeks.

"Today was awesome," Ramirez said. "After [the leadoff homer], I told myself to settle down and keep making pitches and get guys out."

In his last start with Round Rock, Ramirez left the game with two outs in the seventh and the game tied at 1. But Willie Eyre threw a wild pitch, walked the first batter he faced, and gave up two RBI singles, saddling Ramirez with another loss. Despite that, Ramirez remains encouraged by his last two starts.

"It's definitely a step in the right direction," Ramirez said. "It's good to have good life on the fastball and keep it down. I've developed a slider, and that's been a good pitch to have in the arsenal, along with my changeup and curveball."

Gentry likely to return on Wednesday

ARLINGTON -- Rangers outfielder Craig Gentry did not start for the third straight game with a right ankle injury, but should be available on Wednesday.

Despite the Tigers sending out a left-handed starting pitcher in Drew Smyly, the right-handed Gentry was out of the lineup Tuesday. Gentry landed awkwardly on his right foot on his way to first base during Friday's win over the Rockies. He finished the game and started Saturday, but left after three innings.

"I feel good," Gentry said. "I don't write the lineup, but I feel good enough to play today. I went out and tested it out today and did a bunch of different things on it to see how it reacted and it felt good. I'm ready to go."

Gentry ran on the field before Tuesday's game against the Tigers and did not have any issues. "He worked out and did everything," manager Ron Washington said. "There's still a little soreness. The medical staff decided that one more day should do it. He's much further along than the day before. Tomorrow, he should be fine."

In his last 18 games, Gentry hit .452 to raise his batting average to .345. That's the highest average in the American League among hitters with at least 100 at-bats.

Worth noting

• Right-handed reliever Koji Uehara, on the disabled list with a strained lat muscle, is throwing on flat ground and is about a week away from throwing off a mound again.

• Reliever Alexi Ogando, sidelined with a strained right groin muscle, is also hoping to start throwing off the mound again next week.

• The Rangers promoted pitcher Chad Bell from Double-A Frisco to Triple-A Round Rock to replace Martin Perez. Bell, a 14th-round pick in 2009 out of Walters (Tenn.) State, beat Iowa, 3-1, on Tuesday by allowing one run in 5 2/3 innings.

• Double-A Frisco's Chris McGuiness went 2-for-4 in Monday's win over Corpus Christi, the RoughRiders last game before their All-Star break. McGuiness, who was acquired from the Red Sox in a trade for Jarrod Saltalamacchia two years ago, has homered six times in his last four games.
