The Texas Rangers are lucky to be in first place in the American League West because half of their starting pitching staff is injured, with right-hander Alexi Ogando the latest to be sidelined.

Ogando was placed on the 15-day disabled list with a strained right groin muscle and will receive a blood platelet injection to help speed the recovery.

It is likely that Ogando won't be back until after the All-Star break.  He joins starters Neftali Feliz and Derek Holland on the DL. Ogando pitched three innings in the Rangers' 5-0 victory against the San Francisco Giants on Sunday before being injured.

"It was a little more significant than we expected," Rangers general manager Jon Daniels said about the injury. "We're looking at 4-6 weeks before he'll be back on a Major League mound."

The Rangers called up Michael Kirkman from Triple-A Round Rock and newly signed Roy Oswalt is still in Double-A Frisco.
