Kouzmanoff's grand slam highlighted San Diego's five-run 10th inning, and the Padres beat the Indians 8-3 on Saturday night.
While the Padres were waiting for the big hit, a superb pitching effort kept them in the game. Cha Seung Baek, Heath Bell and Bryan Corey held the Indians to four hits. Baek and Bell combined to retire 23 of 24 hitters, including 19 straight.
Kouzmanoff, acquired from the Indians following the 2006 season, hit a 1-1 pitch off Edward Mujica (0-1) into the left field bleachers for his 10th home run of the season and third career grand slam.
Kouzmanoff's first career grand slam came with the Indians on Sept. 2, 2006 against Texas on the first pitch he saw in the big leagues. The third baseman, who put up big numbers throughout his minor league career with Cleveland, was traded to San Diego for second baseman Josh Barfield a few months later.
Kouzmanoff didn't view his home run as revenge against his former team.
"I guess it's kind of bizarre that my first hit was a grand slam and now I'm playing my old team and I hit a grand slam," he said. "It's not like I was out there getting payback against the Indians. I have no negative feelings about the Indians for making a business decision."
Edgar Gonzalez singled with one out in the 10th and went to third on Brian Giles' double. After Adrian Gonzalez was intentionally walked, Tony Clark, battling back from an 0-2 count, walked on a 3-2 pitch.
"That was a very good at-bat," San Diego manager Bud Black said. "It was the key to the inning."
Mujica took issue with plate umpire Rob Drake and thought he struck out Clark on the 2-2 pitch.
"I threw a fastball at the knees," he said. "It was a pretty good pitch. I think the umpire missed that pitch right there."
Kouzmanoff didn't go to the plate with any grand intentions.
"Fortunately, I got a good pitch to hit and put the barrel on the ball," he said.
Jody Gerut, another former Indian, had three hits for San Diego. He singled in a run in the fifth and tied the game with a leadoff homer off Rafael Perez in the eighth. Justin Huber added a solo shot in the third.
Ben Francisco started the ninth with a single off Bell (4-3). Before that, the Indians hadn't had a hit since an RBI double by Shin-Soo Choo with two outs in the first. Cleveland's previous baserunner came on Grady Sizemore's walk with two outs in the second.
After allowing three runs in the first, Baek retired 20 of 21 batters, including the final 16 he faced. The Indians' first was highlighted by Ryan Garko's RBI single, Choo's double and Jhonny Peralta's RBI groundout. Casey Blake flied out to end the inning.
"The most important thing was he got the third out," Black said. "He had all his pitches after the first."
"The first inning was tough," Baek said. "I threw more strikes after that."
Baek, who threw 116 pitches, made just his fourth start of the season and third for the Padres. He pitched 4 1/3 innings and 6 innings in his first two starts for San Diego after being acquired from Seattle on May 28.
"He was throwing his cutter and was using both sides of the plate," Indians manager Eric Wedge said.
Bell retired the side in order in the eighth.
Cliff Lee pitched 6 1/3 innings and left the game with a 3-2 lead, but hopes for his 11th win ended with Gerut's home run. The left-hander allowed eight hits, struck out six and didn't walk a batter.
