The Texas Rangers shuffled the rosters around Friday in order to allow RHP Roy Oswalt to take the mound Friday night in Arlington.
According to the Rangers,
- Purchased the contract of right-handed pitcher Roy Oswalt (#44) from Triple-A Round Rock.
- Placed first baseman Mitch Moreland on the 15-day disabled list, retroactive to Wednesday, with a left hamstring strain.
- Designated right-handed pitcher Mark Hamburger for assignment.
Oswalt makes his debut Friday against the Rockies after four starts in Frisco and Round Rock where he went, combined, 1-1 with a 5.87 ERA (10 ER/15.1 IP), allowing 4 walks against 13 strikeouts.
Oswalt, in his career, is 159-93 with a 3.21 ERA in 339 games. Friday will be Oswalt's first MLB outing since losing Game 4 the NLDS to St. Louis last season.
Following Oswalt in the series against the Rockies will be RHP Colby Lewis on Saturday and LHP Matt Harrison on Sunday.
Mitch Moreland Put on 15-Day DL
Moreland left Tuesday’s game in San Diego in the second inning after suffering the hamstring injury while attempting to beat out a double play ball at first base. He has batted .272 with 10 home runs and 25 RBI in 55 games for Texas this season, starting a team-high 38 games at first base. The earliest date he would be eligible to return is July 5.
Hamburger Designated for Assignment
Mark Hamburger, 25, has spent the season with Triple-A Round Rock, going 0-2 with a 6.55 ERA (33 ER/45.1 IP) in 21 games/3 starts. The Rangers have 10 days to trade, release, or outright Hamburger to the minor leagues.
With these moves, the Rangers still have a full 40-man roster.
