"I'm good. I've proven I can hit an inside-the-parker and a triple, so I'm good," Pierzynski said.
But Volquez gave up precious little after that opening outburst. He finished with seven innings pitched, five hits allowed and two strikeouts with three walks.
"I made better pitches the rest of the way," Volquez said. "I was trying to work deep into the game. That was a problem last year. But I feel more confident in myself. I think I've put everything together to be more consistent in the strike zone."
"I thought it was a great outing after the first 20 pitches," Black said of Volquez. "I think it took him a while to settle in. But once he did, he repeated his delivery, arm slot. I thought his change got better as the game went on."
This game was a one-run battle going into the seventh, thanks in part to a solid effort from White Sox right-hander Dylan Axelrod. He yielded three runs on eight hits over 5 2/3 innings, fanning four and walking three, in this split-squad affair for the White Sox, with Gavin Floyd starting in Scottsdale against the Rockies. The Padres took the lead for good in the fifth with two runs scoring on Chase Headley's double.
Terry Doyle, a Rule 5 Draft selection who recently was returned by the Twins to the White Sox, relieved Axelrod in the sixth and recorded the final out. But he was touched up for six runs in the seventh, capped by Jason Bartlett's two-run double and Andy Parrino's two-run homer to left-center.
Yonder Alonso hit his first Spring Training homer in the second off Axelrod, giving the Padres' Opening Day first baseman a team-best 20 hits. Jeremy Hermida, who hit two home runs Wednesday and has been playing with a strained ligament in his left pinky, knocked out two hits in the victory.
Daniel Robertson tacked on three more during the Padres' four-run eighth with a bases-loaded triple.
