SEATTLE -- Ross Wolf earned his first Major League victory on Wednesday, but it has not guaranteed him another start. The Rangers announced after Friday night's 9-5 win over the Mariners that Martin Perez will start the first game of a doubleheader against the Arizona Diamondbacks on Monday.
Perez missed the first month of the season with a broken left arm but is fully recovered and pitched seven scoreless innings for Triple-A Round Rock against Reno on Tuesday. He allowed three hits and struck out seven.
Wolf would have been on regular rest after Wednesday's 3-1 victory over the Athletics. Wolf, called up from Round Rock because Nick Tepesch had to be scratched with of a blister, allowed one run on three hits and two walks over five-plus innings while striking out three. It was his first start in the Major Leagues and his first appearance there since 2010. But the Rangers decided on Perez.
"Whatever they want me to do. ... If I don't start, I won't be disappointed," Wolf said before Friday's game. "Like I said many times before, I never thought I would make it back up here."
Wolf could move to the bullpen, at least for the twin bill. The Rangers are allowed to carry 26 players for the doubleheader but would have to make a roster move after it is over to get down to 25.
Tepesch ready; Ogando getting close
SEATTLE -- Nick Tepesch is ready to rejoin the Rangers' rotation, and Alexi Ogando is not far behind. Tepesch threw approximately 50 pitches in the bullpen on Thursday without any problems with the blister on the middle finger of his right hand.
Tepesch was supposed to pitch on Wednesday against the Athletics but was pushed back because of the blister. He will start on Sunday against the Mariners.
"It's getting there," Tepesch said. "I didn't feel it in the bullpen at all. It's getting close to where it needs to be."
Ogando, who is on the disabled list with tendinitis in his right triceps muscle, played catch on Friday before the Rangers game with the Mariners and said his arm is feeling much better.
"It's not 100 percent but it's almost," Ogando said.
Ogando will continue to throw this weekend, and the Rangers are planning for him to throw a bullpen session between games during Monday's doubleheader with the Arizona Diamondbacks. If that goes well, Ogando will either pitch one game on rehab assignment or rejoin the Rangers during a three-game series against the Royals next weekend at the Ballpark in Arlington. He is eligible to come off the disabled list on May 31.
"We'll know more about where he is and when he's coming off after he throws that bullpen session," manager Ron Washington said.
Moreland moves up to No. 2 spot
SEATTLE -- David Murphy was out of the lineup on on Friday night with Mariners left-hander Joe Saunders on the mound, so Mitch Moreland was moved up into the second spot in the lineup. Manager Ron Washington had moved Murphy into the No. 2 spot when Ian Kinsler went on the disabled list.
Murphy is 5-for-18 with two home runs in five games as the No. 2 hitter and is hitting .314 with four home runs and 11 RBIs in his last 17 games. Washington said he thinks moving Murphy up in the order helped him come out of his slump.
"Just gets him involved in the game [quicker]," Washington said. "He's not waiting around. When you're struggling and waiting around, it can weigh on your mind. Now we're getting him in the game quicker rather than him having to wait around for the second or third inning to get an at-bat."
Moreland doesn't need such help. He went into Friday's game hitting .343 (23-for-67) with five doubles, seven home runs and 14 RBIs over his past 19 games. But Washington didn't want his two left-handed hitters -- Moreland and Pierzynski -- hitting back to back in the lower half of the order. Pierzynski was hitting sixth.
Washington said Moreland will be back to the lower half of the order on Saturday with right-hander Felix Hernandez on the mound.
"If he goes 4-for-4 there tonight, he won't be [hitting second] tomorrow," Washington said.
Olt is working out again
SEATTLE -- Rangers infielder Mike Olt, who has been sidelined for a month because of blurred vision, has been cleared to resume baseball activities. Olt has been seen by several eye specialists and has been taking medication and eye drops to clear his vision.
Olt has been sent to the Rangers' training complex in Surprise, Ariz., to begin working out again. He will work up to game action and then be assigned to Triple-A Round Rock.
Olt, the No. 21 ranked prospect on the MLB.com Top 100, has not played since April 25. At the time, he was hitting .139 with one home run and six RBIs. In 72 at-bats, he struck out 32 times.
• Pitcher Brad Mills was activated off the disabled list on Thursday night at Round Rock and pitched two scoreless innings in relief against Reno. Pitcher Nick McBride was transferred from Round Rock to Double-A Frisco.
• Ross Wolf was the first starting pitcher used by the Rangers this season who is at least 30 years old. The Rangers were the last American League team to use a thirty-something starting pitcher this year.
• Rangers pitchers entered Friday's game having allowed just one run in each of their last two games. They have allowed one run or fewer in 12 games, most by an AL staff so far this season.
• Adrian Beltre hit his 10th home run on Wednesday. Nelson Cruz has 11 and Moreland has 10. The Rangers and the Blue Jays are the only two teams with three players with at least 10 home runs. There are 14 teams that don't have one player with at least that many.
