Rangers starter Matt Harrison leaves Tuesday's game with back stiffness
Harrison made only two starts last year and was making only his fourth of this season after undergoing two surgeries on a herniated disc in his lower back. He allowed three runs on four hits and three walks on Tuesday and was tagged with the loss.
The 28-year-old, who is 6-foot-4 and 240 pounds, was an All-Star in 2012, when he went 18-11 with a 3.29 ERA in 32 starts.
There was no word on the severity of the injury, according to T.R. Sullivan of MLB.com. The temperature in Houston was a cool 66 degrees at the start of the game, Sullivan reports, and the roof was open at Minute Maid Park.
Harrison is 1-1 with a 4.15 ERA in four starts this season with 10 strikeouts and 12 walks in 17 1/3 innings. SI WIRE: Marlins pitcher Jose Fernandez will seek second opinion on Tommy John surgery
