Wojciechowski will compete for the fifth spot in the Astros' starting rotation this spring, Brian McTaggart of MLB.com reports.

Wojciechowski, who missed all of last year's camp with a strained lat muscle, is healthy entering 2015 and will compete with Dan Straily, Roberto Hernandez, Brad Peacock (hip), Alex White, Jake Buchanan and Samuel Deduno for the final spot in Houston's starting rotation. The 26-year-old right-hander appeared in 15 games (14 starts) at Triple-A last season, going 4-4 with a 4.74 ERA. He'll need a strong camp to win the job over the veteran starters he's competing with.

Wojciechowski earned his first win of the season for Triple-A Oklahoma City on Wednesday, allowing three runs on seven hits and two walks with five strikeouts over 5.1 innings.

Wojciechowski's five strikeouts tied a season high, and his 5.1 innings were the most he's pitched in an appearance this season. The 25-year-old continues to build up his strength after missing four months with a strained right lat muscle.

The Astros don't think it's serious, but Wojciechowski won't appear in game action for a couple weeks. He's missed all season with a strained lat. "It's nothing too severe in his forearm," general manager Jeff Luhnow said. "Because he's coming off of the other injury and wasn't feeling 100 percent right we had a doctor look at him. We don't think that there's any real issue, but he's not going to throw in a game for the next two weeks. He's going to go to Florida and rehab and throw right there."

Wojciechowski has been nursing a strained right lat since the beginning of camp and had a setback Sunday when he attempted to throw softly into a net for the third straight day. "I think the first time we tried to get him going we realized he wasn't quite ready," general manager Jeff Luhnow said. "We want to be a little more conservative this time around so we're being very cautious." Luhnow added that he doesn't expect Wojciechowski to miss more than "the first couple of weeks of the season." The righty will surely be assigned to Triple-A Oklahoma City once he's healthy.

Asher Wojciechowski flew to Houston to receive a platelet-rich plasma injection in his right lat muscle.

"It's supposed to help with the recovery time," Wojciechowski said. The right-hander hasn't been showing improvement in the muscle in recent days, so the injection may be the trick. The 25-year-old will return to Florida late Thursday, but it's unclear how long he'll remained sidelined.
