"I was looking forward to it," Ohlendorf lamented. "I certainly wish it had gone better.
"The first three innings I felt like it went very well, and then I just didn't make as good a pitches in the fourth inning, and they took advantage of it."
Pirates' lefty Eric Bedard survived a shaky start and toiled for five innings. He surrendered five runs (three earned) on five hits and got the win, upping his record to 7-12.
The Pirates bullpen was strong closing the door on the Padres. Chris Resop, Chad Qualls, Juan Cruz and Joel Hanrahan all tossed scoreless innings for Pittsburgh.
Padres leadoff hitter Chris Denorfia deposited an 0-1 offering from Bedard into the San Diego bullpen in the first. Logan Forsythe drew a walk, Carlos Quentin was hit by a pitch and then Jesus Guzman delivered an RBI single.
The Pirates first-inning woes continued when shortstop Clint Barmes committed a three-base throwing error on a Cameron Maybin grounder, allowing Quentin and Guzman to score and staking the Padres to a 4-0 lead.
"Denorfia set a good tone with that homer," manager Bud Black said. "We've been doing that a little bit lately homering in the first inning. From there we kept going, built that lead. Ohlendorf threw the ball well the first three innings and made some pitches. Then they ambushed us there in the fourth and couldn't make pitches along the way to stem the tide."
The Padres tacked on another run in the second. With one out, Forsythe doubled, and he came home on a RBI ground ball by Chase Headley that was fielded by catcher Michael McKenry, but Forsythe was able to score when nobody covered home plate for the Pirates.
The Pirates nicked Ohlendorf for a run in the third inning. With one out Bedard doubled, and he scored on a two-out single by Neil Walker, cutting the Padres lead to 5-1.
Pittsburgh struck again in the fourth. Garrett Jones drew a walk. Gaby Sanchez reached base on an error by Headley. Pedro Alvarez singled to load the bases. McKenry drew a walk that plated Jones. Barmes, who had a rough day in the field with two errors, smacked a grand slam off the left-field foul pole, giving the Pirates a 6-5 lead. It was home run No. 6 for Barmes for the season, and it was the first grand slam of his career.
"I was just trying to put a barrel on the ball, and do something to at least get one run in, or to keep it going," Barmes said. "I hit it well, obviously. At that point, as soon as I hit it, I saw it starting to hook, and it was one of those where I was just hoping it stayed fair."
The Bucs' onslaught continued after right-hander Cory Burns replaced Ohlendorf following a walk to Bedard. With one out, Walker singled. Andrew McCutchen doubled to knock in Bedard and Walker, and Jones tripled to plate McCutchen. With two outs, McKenry singled to bring home Jones. When the smoke cleared, the Pirates had a 10-5 lead. The nine runs were the most that Pittsburgh had scored in an inning since July 20, 2010, against the Brewers.
"The whole inning was just bad," Ohlendorf explained. "The grand slam was really bad. The leadoff walk, the whole inning, I just wasn't very sharp."
"If you've been around this game long enough you run into those innings where everything they do works and everything you try to do doesn't," Black said. "The momentum keeps going and you can't stop it. You've got to take it, you do, it's part of this game at times. The other team gets on a roll and you try to stop it the best you can, and sometimes you can't."
Pittsburgh added another insurance run in the seventh on Walker's leadoff solo home run. It was home run No. 14 for Walker, and the hit was his fifth. It was the third time he has tallied five hits in a game in his career, and second time this season.
The Padres continue their road swing with a four-game series in Atlanta starting Monday night.
