HOUSTON -- Taijuan Walker left a start early for the third time this season because of the same foot problem on Tuesday against the Houston Astros, which left the Seattle Mariners searching for how to eliminate the issue.Walker (4-7) yielded five hits and five runs before leaving after four innings with discomfort in his right foot. He also left early because of his foot on June 14 and June 19.Taijuan obviously still isnt quite right, manager Scott Servais said. He struggled, and hes trying to pitch through it, but we probably have to re-evaluate where we are at here. We will have it looked at again.Walker is frustrated that this issue has lingered for so long.I feel like I just havent had my best stuff, he said. My [velocity is] down. My changeup isnt as sharp. Nothing is really as sharp just because I cant get into my legs and get after it. Its probably not best for me to go out there and pitch because I cant give it 100 percent.The Mariners lost to the Astros 5-2.First two innings was good. I was able to drive, Walker said. After the second inning, I had no legs. Everything was up. Everything was running back to the plate. I just couldnt drive it in there.Information from The Associated Press was used in this report.
