CINCINNATI (AP) -- Will Venable homered for the second game in a row, and San Diego's depleted offense took advantage of Cincinnati's season-high four errors for a 3-1 victory over the Reds on Saturday night.
Third baseman Jack Hannahan had three of the errors -- two on off-target throws to first base, another on a grounder that got through him. All San Diego managed off the errors was two unearned runs.
Venable hit his team-high 15th homer in the eighth inning off reliever Manny Parra.
Tyson Ross (3-5) gave up Brandon Phillips' RBI single in the first, one of only four hits he allowed over seven innings. Huston Street pitched the ninth for his 22nd save in 23 chances.
Three of Cincinnati's errors came behind Tony Cingrani (5-2), who had to throw a lot of pitches to make up for the extra outs. The left-hander needed 92 to get through five innings while allowing only two hits and two unearned runs.
The Padres have won their last six games against left-handed starters since July 11.
The Reds had a tough time holding onto the ball all around. Catcher Devin Mesoraco threw over Hannahan's head while trying to toss the ball around the infield after a strikeout.
The Padres put outfielder Carlos Quentin on the 15-day disabled list with a strained right knee before the game, their second significant setback of the week. Earlier, All-Star shortstop Everth Cabrera was suspended for 50 games for taking a banned substance.
Quentin missed the last seven games with the injury. He was batting .275 with a team-leading 45 RBIs and 13 homers, second to Venable for the team lead.
The Padres got sloppy and let in a couple of runs in Cincinnati's 7-2 win on Friday night. This time, the Reds had trouble getting a grip.
Chris Denorfia singled and scored when Venable singled and left fielder Xavier Paul bobbled the ball. Hannahan then threw wildly to first on Chase Headley's grounder, allowing Venable to score on the second error of the inning. Cingrani threw 32 pitches in the extended inning.
Shin-Soo Choo drew a leadoff walk in the bottom of the first, stole his 13th base of the season and came around on Phillips' two-out single.
Paul ran the Reds out of a rally in the seventh. Jay Bruce walked and went to third on Paul's single with no outs. Mesoraco flied to Denorfia in right, not deep enough to get Bruce in from third. Paul tagged on the play and was thrown out at second.

The Padres called up OF Jaff Decker to take Quentin's spot. ... LF Ryan Ludwick rejoined the Reds on Saturday from his minor league rehab stint. The Reds plan to activate him before the start of a series on Monday in Chicago. Ludwick has been sidelined since he tore cartilage in his right shoulder while sliding into base on opening day. ... Hannahan's three errors were a career high. ... On Sunday, Mike Leake (10-5) makes his first start since he got roughed up in a 15-2 loss to St. Louis a week earlier. Ian Kennedy (4-8) makes his second start with the Padres, who got him from Arizona on July 31.
