Martin Perez worked two perfect innings in his first Cactus League start, but Justin Grimm surrendered three runs in the third and Neil Ramirez caughed up five in the eighth as Colorado dropped the Rangers at Salt River Fields in Scottsdale.
Perez needed only 27 pitches to complete his work. He struck out Troy Tulowitzki looking with a fastball to end the first, and got Josh Rutledge to swing at a slider out of the zone to end the second.
The left-hander, competing with four others for the final spot in the rotation, said that he made a quick adjustment to the first batter after falling behind 3-1 that changed the course of his outing.
"To pitch in the big leagues, you have to be able to make adjustments," Perez said.
Grimm, also vying for the fifth spot, allowed three runs in the third but rebounded with a scoreless fourth. He got in trouble by elevating his pitches.
"You're not going to make a very good living living up in the zone," he said. "I rebounded well the next inning. I started fresh and said I was just going to go after them."
Ian Kinsler drove in the lone Rangers run with a sacrifice fly in the fifth to plate Leonys Martin, who had two of the Rangers' five hits.
