ARLINGTON (AP) – The Texas Rangers plan to promote right-hander Justin Grimm from Double-A Frisco for his major league debut in a start against Houston on Saturday night.

General manager Jon Daniels said Thursday that the Rangers will purchase Grimm’s contract before Saturday’s game, when they also plan to make other corresponding moves. Grimm will join the big-league club before that to work out with the team.

Grimm, a fifth-round draft pick two years ago, was 8-3 with a 1.87 ERA in 13 starts for Frisco. He had 67 strikeouts and 14 walks.

When the Rangers purchase Grimm’s contract, they plan to put right-handed reliever Koji Uehara on the 15-day disabled list to clear a spot on the 25-man roster. That move will be retroactive to Sunday, the day after Uehara last pitched and he strained a back muscle at San Francisco.

To clear a spot on their 40-man roster, the Rangers will transfer right-hander Neftali Feliz (sprained right elbow) from the 15-day disabled list to the 60-day DL. The earliest he will be able to return is July 17, though Daniels emphasized that there have been no setbacks in the hard-thrower’s expected recovery.

Grimm will take the starting spot of Alexi Ogando, who is out four to six weeks after straining his groin running out a bunt single Sunday in San Francisco. Ogando, a 13-game winner and an All-Star as a starter last season, threw three perfect innings in his first start this year when he got hurt. He was pitching in place of Derek Holland, who is also on the disabled list.

Daniels said it could be more than only a sport start for Grimm, though the Rangers have an off day before that spot in the rotation would come up again after Saturday.

Three-time All-Star Roy Oswalt, who signed a minor league deal with the Rangers last month, is scheduled to start Sunday for Triple-A Round Rock. That will be the right-hander’s fourth minor league start, but it was unclear if Oswalt would be ready to join the Rangers rotation after that.

Daniels said Oswalt is scheduled to throw around 100 pitches Sunday. In three starts so far with Round Rock and Double-A Frisco, Oswalt is 0-1 with a 7.71 ERA, allowing eight runs in 9 1-3 innings.

Holland could be eligible to return next Thursday, but he also has to rebuild his strength. He was put on the disabled list because of shoulder fatigue after losing about 15 pounds over a two-week period because of stomach virus.
