Gonzalez and Kouzmanoff opened the inning with singles off Giants starting pitcher Tim Lincecum, who allowed one run in six innings with seven strikeouts, brandishing a nasty changeup to go along with his mid-90s fastball.
Lincecum then hit Jim Edmonds with a pitch to load the bases. Khalil Greene then lifted a fly ball to left field that sent Daniel Ortmeier backpedaling toward the wall. The hit went in and out of Ortmeier's glove as a run scored to cut the Giants' lead to 2-1.
But Kouzmanoff, who was on second base, thought Ortmeier made the catch. The Giants (2-6) got the ball back into the infield and got a forceout on Kouzmanoff at third base for the first out. Lincecum then got the next two hitters out to end the inning.
"I saw it go into his glove and I immediately went back to tag up," Kouzmanoff said. "I saw Edmonds at second base. I don't know what happened."
Neither did Padres manager Bud Black, who said there was a division of opinion inside the dugout on whether Ortmeier made the catch.
"I thought that he caught it," Black said. "The guys on the bench were wondering what happened, too."
