After retiring only four batters over his first two starts while allowing six runs, Wolf and pitching coach Darren Balsley talked briefly last week about the left-hander's command issues.
It was a short talk and, as it turned out, a small fix that, apparently, set Wolf straight and got him throwing more strikes by keeping his curveball and changeup down in the strike zone more than it had been.
"I think a lot of it goes back to a conversation I had with Darren after my last game. He made it really simple the adjustment as far what direction I was going [in his delivery]," Wolf said. "It made a lot of sense. The next day I threw in the bullpen. Everything was down."
That was the case Sunday when Wolf allowed two runs in three innings with no walks and five strikeouts in the Padres' 12-3 victory over the Chicago White Sox at the Peoria Sports Complex.
"Mechanically, I feel a lot better. The whole time my arm has felt great. I knew there was something off in my delivery. It's frustrating because the adjustment you have to make is pretty small," Wolf said. "It made a pretty big difference."
Wolf allowed five hits but mostly avoided damage -- one run scored on a wild pitch -- as he was able to bury his curveball down in the strike zone. Better still, the curveball, his best pitch along with his fastball, has what Wolf called "the right kind of action."
Wolf said that the adjustment had more to do with his legs and shoulders than his arm.
"The thing he [Balsley] was telling me was when I was going to the plate, I was pushing out straight. It was almost like I was pitching uphill, I was leaving everything up."
San Diego manager Bud Black was encouraged by Wolf's start, not just his curveball but his changeup, a pitch that Wolf is working diligently to use more this spring. Wolf got a handful of bad swings on his changeup.
Bad break: Outfielder Vince Sinisi was in the clubhouse Sunday wearing a sling to protect the broken right wrist he suffered in Saturday's victory over the Rangers when he attempted to make a sliding catch in sixth inning of the game in Surprise.
"I got my wrist caught up under my glove," Sinisi said. "My glove hit the ground and my wrist bent back."
Sinisi broke the wrist in two places and will have surgery Monday, according to Black.
Sinisi said it will likely be anywhere from four to six weeks before he can remove a cast from his wrist and then three to four weeks before he can resume any baseball activities.
"It's going to be right around a couple months I think before I can play," said Sinisi, who was hitting .500 in 10 at-bats this spring before the injury.
"It's unfortunate. It seems like I've had enough injury stuff now where, I hate to say I'm used to it, but it's something I'm used to dealing with it. So you just roll with it and move on," said Sinisi, who has had a broken left arm, knee surgery and even a rib removed, all from playing baseball.
Sinisi was originally on the Padres' traveling roster for the games next week in China.
Black has experience with this. In Anaheim, he presided over a staff that included Jered and Jeff Weaver. Last season, the Padres had Brian and Marcus Giles the entire season.
And during his playing days, Black was on the same team in San Francisco with Barry Bonds and his father and Giants coach, Bobby Bonds.
"I think it's great, a special time in their life," Black said. "It's wonderful to look across the room and see their brother."
Friar notes: As part of their team building exercises, Black had Minor Leaguers Mike Baxter and Wade LeBlanc give a report -- complete with a presentation featuring a visual aid -- on China. The report provided some historical essentials as well as where to get Pizza Hut on the trip. ... Given Jim Edmonds' injured right calf, which could keep him out of action for at least two to three weeks, if not longer, the Padres considered keeping outfielder Scott Hairston stateside instead of having him make the trip to China. Hairston will instead start games on Sunday and Monday and again during the weekend in Beijing and won't miss many reps in center field, a spot he could end up in if Edmonds isn't ready for Opening Day. ... After working out Sunday morning, Mark Prior was allowed to go home after feeling ill. Outfielder Jeff DaVanon was excused from playing on Sunday as he has a case of strep throat.
Up next: Justin Germano gets the start on Monday against the Texas Rangers at the Peoria Sports Complex at 7:05 p.m.. This will be Germano's last Cactus League start before he heads to China with a Padres contingent on Tuesday. Germano, in the mix for the vacant No. 5 starter spot in the rotation, is scheduled to start a game against the Los Angeles Dodgers in Beijing.
