"Everyone will fret about the two home runs Jeff Karstens served up Tuesday night to Alfonso Soriano.

Karstens, however, was more upset about a pitch that never left the infield but still played a huge role in the Pirates' 3-1 loss against the Chicago Cubs.

"The fastball that I jerked that got away from Doumit was a big one," Karstens said.

With one out in the second inning, Koyie Hill doubled to left. Hill went to third on what was scored a passed ball - Doumit set up down and away, but the pitch veered well out of the strike zone and ticked off Doumit's glove.

"It's on me," Karstens said. "It was supposed to be down and away. I threw it too far."

Starlin Castro flied out to left field. Jose Tabata's throw was up the line toward first base, enabling Hill to dodge Doumit's swipe tag and score standing up.

Soriano homered to left in the fourth and again in the sixth. Each time, there were two outs.

"The home runs are going to come," Karstens said, "but in a situation with two outs ... it can't happen like that."

It was Soriano's 25th multi-homer game and the second time he did it this season. The blasts gave him six hits in 11 career at-bats against Karstens."
