"The Rangers have placed RHP Rich Harden on the disabled list with a left gluteal muscle strain. To take his place on the roster, the Rangers have recalled RHP Alexi Ogando from Triple-A Oklahoma City . The Rangers can go without a fifth starter in their rotation until a week from today at Houston. It's possible they could return Ogando to the minors at that point and recall either RHP Doug Mathis or RHP Guillermo Moscoso or they could keep Ogando and pitch the game out of the bullpen with either LHP Matt Harrison or RHP Dustin Nippert getting the start.
