Walker allowed two runs on seven hits with four strikeouts and no walks in six innings Friday in the Mariners' home opener against the Athletics.
Walker, who did not receive a decision in the loss, had some trouble with his command -- he gave up seven hits in five innings before retiring the side in order in the sixth. A couple errors led to an elevated pitch count, as well, and he was done after 100 pitches. He escaped with only two runs allowed thanks to a couple inning-ending double plays and a couple timely strikeouts. It was a decent season debut, but he wasn't dominant.
