GLENDALE, Ariz. (AP) -- Once Edinson Volquez settled down, he sure looked ready for the regular season.
Volquez pitched seven solid innings to help the San Diego Padres beat a Chicago White Sox split-squad 13-2 on Wednesday.
The right-hander, who will be the Padres' No. 3 starter, allowed two runs and two hits in the first inning, but held the White Sox to no runs and three hits for the rest of his outing.
"I was way better (after the first inning)," said Volquez, who struggled in the first last year, when he was with the Cincinnati Reds. "I made better pitches the rest of the way."
Volquez struck out two and walked three in the longest outing of the spring for the Padres.
"It was a great outing after the first 20 pitches," Padres manager Bud Black said. "The next 73 were outstanding. It took him a little while to settle in. But once he did, it was a delivery he repeated, repeated his arm slot, repeated his finish. All three pitches were working. The (changeup) really got better as the game went on."
Yonder Alonso, Chase Headley and Andy Parrino homered for San Diego, which had 18 hits.
Headley hit a two-run drive for his third homer of the spring. He also had a two-run double.
Parrino's two-run shot was his fourth homer, and Alonso's solo drive was his first of the spring.
White Sox starter Dylan Axelrod allowed three runs and eight hits in 5 2-3 innings. He struck out four and walked three.
Axelrod, who posted a 2.89 ERA in 18 2-3 innings with the White Sox last season, is competing with four pitchers for two bullpen spots.
"I've had some really good outings and a couple poor ones," said Axelrod, whose ERA is 5.95. "My ERA isn't good, but I feel like a couple innings have gotten away from me, kind of blew up my ERA a little bit. I'm not happy with it, but I'm not terribly disappointed either."
Chicago catcher A.J. Pierzynski had a run-scoring triple and is batting .268 this spring. He likely will be the No. 2 hitter in the lineup.
"That's all I've been trying to do all spring, not do too much and put the barrel on the ball and let it go where it goes," Pierzynski said. "I've been squaring some balls up, and they've been hitting the gaps and a couple of balls have got out."
