SAN DIEGO (AP) - Tony Gwynn Jr. reached base a career-high five times and scored the go-ahead run in the six-run sixth inning to help the San Diego Padres beat the Arizona Diamondbacks 6-4 on Saturday night, snapping a four-game losing streak.

The big inning snapped a string of 15 scoreless innings for the Padres, who lost 8-0 to the Diamondbacks on Friday night and hadn't scored since the eighth inning of a 5-1 loss to the Philadelphia Phillies on Wednesday night.

Gwynn was obtained in a trade with Milwaukee on May 21, joining the team his Hall of Fame father played with for 20 years. Gwynn had a career-high three walks, a single, double and a stolen base.

Kevin Correia (2-4) rebounded from a shaky first inning to earn the win, holding Arizona to two runs and five hits in six innings, with four strikeouts and one walk. Heath Bell gave up one run on a walk, a wild pitch and two grounders in the ninth for his 16th save in 17 opportunities.

Correia allowed two runs on three hits, a walk and a hit batter in the opening inning. But starting with the final batter of the first, he retired 15 of the last 17 Diamondbacks he faced. After throwing 34 pitches in the first, he threw 49 pitches over the next five innings.

Trailing 2-0 after stranding eight runners through the first five innings, the Padres finally broke through against three pitchers in the sixth. Will Venable had two hits, an RBI and scored a run that inning.

Venable hit a leadoff double and scored on Chris Burke's one-out, broken-bat RBI single that bounced off reliever Leo Rosales' foot and into left field. After pinch-hitter Edgar Gonzalez flied out, Rosales made way for rookie Daniel Schlereth.

Schlereth (0-2) faced four batters and failed to get an out, allowing four runs on one hit, two walks and a hit batter. He walked Gwynn, allowed David Eckstein's RBI single to tie the game, walked Adrian Gonzalez to load the bases and then hit Chase Headley on the top of his left foot with a pitch to bring in Gwynn with the go-ahead run.

Brian Giles, who stranded seven runners in his first three at-bats, including four in scoring position, followed with a two-run single to right off Clay Zavada, and Venable had an RBI single.

Stephen Drew hit an RBI single in the first for the Diamondbacks, extending his hitting streak to 10 games. Eric Byrnes had two RBIs, including on an infield single in the first. Justin Upton homered off Edward Mujica in the eighth, his 11th.

Arizona starter Max Scherzer allowed three hits in five scoreless innings, struck out six and walked five.
