Jinx or no jinx, Peavy was handed a 4-0 lead before he even took the mound, but the Padres ace still wasn't able to hold onto the lead, as the D-backs came back for an 8-6 win.
Based on the pitching matchup, the game should have been a low-scoring affair with two of baseball's top pitchers squaring off.
Dan Haren didn't fare much better against the Padres. After giving up two doubles to lead off the game -- one to Jody Gerut and the other to Tadahito Iguchi -- the D-backs co-ace then allowed a two-run homer to Kevin Kouzmanoff, making the score 4-0 just five batters into the game.
But in the bottom of the inning, Peavy (9-9) encountered some early trouble when he allowed a double to No. 2 hitter Augie Ojeda and a walk to Conor Jackson. Then the big blow came from Padres-killer Adam Dunn, who hit a three-run homer. Dunn has five home runs and 13 RBIs in nine games against the Padres this year.
"Dunn's blow was big," Padres manager Bud Black said. "I think Jake just tried to throw a fastball away, but he sort of left it middle in.
"That's not Jake's game. Jake's usually in and around the zone, especially when he has the lead. This wasn't typical Jake."
The D-backs scored three more runs -- two earned -- in the second off Peavy, good for the most he's allowed all season.
"It's disappointing," Peavy said. "We come out against a guy like Dan Haren, who has been as good as anybody all year, and we score four before I take the field. That's just unacceptable when you can't hold that lead."
Peavy also allowed four walks, the second-highest total of the season. He was relieved after five innings by Clay Hensley then Wil Ledezma, who each allowed a run in the seventh inning. Hensley and Ledezma allowed two walks each.
Four of the eight hitters who walked ended up scoring. This came just one night after Padres starter Josh Banks allowed seven walks -- four of which ended up scoring.
"We can't walk eight guys," Black said. "Here and anywhere, eight walks does not cut it. I believe a lot of those came back to haunt us."
The Padres now have 25 hits through the first two games of the series, but only have scored 12 runs in that span -- both losses. They are getting clutch hits as well, as they are hitting .400 (8-for-20) with runners in scoring position.
Three Padres had multi-hit games, including Gerut (3-for-5), who pushed his batting average to .303. In the ninth inning with two outs, Gerut smacked a 385-foot solo home run -- his 13th -- to right field off Jon Rauch on a 1-2 count.
"I was just trying to protect and extend the game and that was it," Gerut said.
Brian Myrow tacked on a pinch-hit RBI single in the seventh inning.
For the D-backs, in the second inning after Chris Snyder hit a solo home run, Peavy walked the pitcher Haren. Haren advanced to third on the following play after a fielding error by Brian Giles when Stephen Drew singled to right. Conor Jackson hit a two-run single to score Haren and Drew.
"I just couldn't throw the ball where I wanted to throw it," Peavy said. "Mechanically, I was a little bit off.
