Right-hander Kyle McClellan, considered a candidate for the Rangers' rotation and the bullpen, will miss the start of the regular season with a strained lat muscle.
He won't be allowed to resuming a throwing program for three to four weeks. Opening Day is in 15 days.
McClellan, who had shoulder surgery in July, had been slowed by a sore shoulder this spring, but worked two scoreless innings in his Cactus League debut Tuesday against Milwaukee.
With McClellan out, the competition for the fifth spot in the rotation is down to Robbie Ross, Randy Wells, Nick Tepesch and Justin Grimm. McClellan was also in the mix for a bullpen spot had he failed to make the roster as a starter.
