Wolf, who did not play last season after having Tommy John surgery in 2012, scattered two hits and two walks, while striking out three on 73 pitches.
“Thought he was a little bit sharper than the last couple times out,” Seattle manager Lloyd McClendon said. “It was a good outing for him.”
Wolf, a 37-year-old left-hander vying for a spot in the rotation, said he considered more than results when assessing his performance.
“To me it’s about getting stronger and better every time out as far as the sharpness of your pitches and my strength, durability,” he said.
San Diego starter Josh Johnson also pitched well, throwing 4 1/3 innings, allowing one earned run on three hits, two walks and five strikeouts.
Seattle infielder Brad Miller took advantage of Johnson’s only miscue, hitting his fourth homer of the spring in the third inning.
Miller, battling Nick Franklin for the starting shortstop role, finished 3 for 4 with a triple and three runs.
“He has the ability to hit the ball out of the ball park,” McClendon said. “No question about it, had a good game tonight, played very well.”
“I was feeling beat up before spring training (last year),” Johnson, who battled arm injuries throughout the 2013 season and suffered through the worst of his nine Major League seasons.
Johnson said he feels “right and normal” now and he pitched well enough against Seattle to support that claim.
“Everything has kind of gone exactly to plan, if not better,” he said. “It’s been good so far. Just got to keep gong and keep getting out there and progressing like I have been.”
