Mariners pitcher Taijuan Walker threw 48 pitches in three innings in a minor-league game Tuesday, MLB.com reports.
"My arm felt good; I just got tired," Walker said. "But that's to be expected. I used my legs a lot today, which was a good sign. I wanted to use more legs, less arm. But my arm felt great."
Walker is going to start the season on the disabled list after dealing with a sore shoulder this spring. He's slated to throw another minor-league game this weekend.
