Nick Martinez turns 24 on Tuesday.
But first the right-hander has one more start at 23, a year that has been full of opportunity for the rookie.
Martinez made his first Major League start April 5, and was later added to the rotation as the injury bug continued to take its toll on the Rangers. He enters Monday's matchup with the White Sox with a 1-7 record and a 5.08 ERA in 13 starts and five relief appearances.
His only win was on May 24 against the Tigers, and he is 0-6 with a 7.31 ERA in his last nine starts. The Rangers are 1-8 in those starts.
Now he is trying to show the Rangers that he can be a serious candidate for a spot in the rotation next season.
"I feel like I'm learning every time I take the mound. As a competitor, it's a little frustrating," Martinez said. "It's not the kind of year I want, but the season is almost over so I have to finish strong."
Rangers manager Ron Washington said he knows what Martinez is capable of, now it's just a matter or consistently executing it.
"He's got stuff, he just has to figure out how to use it and figure out how to get out of tough situations by making pitches," Washington said. "It's all about consistency. Being able to go out and consistently do it. That's when you've arrived."
Martinez will match up with Hector Noesi for the White Sox, who actually pitched with the Rangers earlier in the season after they acquired him from the Mariners April 12. Almost two weeks later, on April 25, the White Sox claimed him off waivers. In his brief stint with the Rangers, Noesi faced the White Sox, giving up seven runs in an inning. In his last start against the Tigers, he allowed six runs on six hits in the first inning alone. He managed to settle down after the first, giving up four hits and no runs in the five innings after that.
"He's had games where he has been very tough and in Detroit he had the first inning that really hurt him," manager Robin Ventura said. "But from where we were to where we are at now with [Noesi and Scott Carroll] even when they are going in there, you feel like you've got a shot. They've been doing well enough for us to win games."
White Sox: Ventura pleased with offense
Since July 1, the White Sox have scored at least six runs on 11 occasions.
Ventura has been pleased with his team's offensive productivity as of late, but said the challenge comes in limiting the opponents on a consistent basis.
"If you get down, you still feel like you can come back and score runs and stay in games. That part is good," Ventura said. "It's being able to hold the other team and give yourself a shot at it. The last couple of nights, one night you do get it and one night you don't. To be consistent you are going to have that back-end really shut them down."
Rangers: Holland set for next rehab start
Rangers pitcher Derek Holland, who has been on the disabled list all year after offseason surgery on his left knee, will make his second start on a medical rehab assignment when he pitches for Triple-A Round Rock against Memphis on Monday. Holland is scheduled to throw three innings and 50 pitches in Game 1 of a doubleheader.
Holland made his first start last Wednesday for Double-A Frisco against Midland and pitched two scoreless innings. He walked two and struck out four on 33 pitches.
"Just trying to get out there and get back into the swing of things," Holland said. "First time out, very excited, a lot of adrenaline flowing, but the main thing was I just wanted to execute my pitches. I felt like overall a couple bad walks, but for the most part I'm feeling really good about how I was out there doing everything."
• The Rangers have lost seven of their last eight at U.S. Cellular Field and are 7-10 there since the start of 2009.
• Rangers shortstop Elvis Andrus, with a first-inning double on Sunday, has a 10-game hitting streak. It's the fourth hitting streak of 10 or more games he has had this season.
• White Sox designated hitter Adam Dunn didn't play Sunday, but with a right-hander pitching Monday, he should be back in lineup.
