PEORIA, Ariz. -- It's hard to imagine Taijuan Walker pitching much better or doing much more to impress in his battle for the Mariners' fifth-starter position, but the 22-year-old insists there's more in the tank even after running his scoreless streak to 18 innings this spring in Wednesday night's 3-2 victory over the Cubs.
"You can always be better," Walker said after holding the Cubs to two singles and a walk in six frames. "Zero walks. Especially toward the end, I got a little tired. As spring goes on, that kind of goes away."
