Manager Lloyd McClendon shook his head.
What more does Walker have to do?
“Stay consistent; keep pitching well,” McClendon said. “He threw up a lot of zeros and pitched well. He fatigued a little bit in the sixth, but I thought he threw the ball extremely well.”
Walker gave up two hits, both singles, while walking one and striking out six. He threw 57 of 82 pitches for strikes and extended his spring scoreless streak to 18 innings through five starts.
“It feels good,” Walker said. “I’m just trying to go out there and attack, really. Everything feels really good. Mechanics, arm, everything.”
Second baseman Robinson Cano backhanded the ball and flipped it to shortstop Brad Miller, who threw to first for the out.
Both games start at 1:05 p.m.
Felix Hernandez will start against the Royals, who list right-hander Jeremy Guthrie as their starter. Roenis Elias will start against the Brewers, who plan to start right-hander Mike Fiers.
