DENVER — Will Venable homered and tied a career high by driving in four runs in the San Diego Padres' 6-3 win over Colorado on Wednesday night that snapped the Rockies' eight-game home winning streak.
The Rockies' lead in the NL wild-card race was whittled to four games over Atlanta, which beat New York 5-2, and San Francisco, which beat Arizona 5-2.
Venable hit a solo homer in the second, his 12th, and added a three-run double in the fifth off right-hander Jason Marquis (15-12), who failed for the third time to win his career-best 16th game.
Reliever Ryan Webb (1-0) got the win with one inning of scoreless relief and Heath Bell pitched the ninth for his 40th save in 46 tries.
With one man on and two outs, Troy Tulowitzki was rung up by home plate umpire Rob Drake on a full-count off-speed pitch that the shortstop thought was high and tight for ball four.
Marquis was tagged for six runs, five of them earned, on five hits and five walks in just 4 2-3 innings. Matt Herges replaced him with two men on his error covering first on Tony Gwynn's chopper allowed Venable to score and make it 6-0.
Right-hander Tim Stauffer took a no-hitter into the fifth inning but left after allowing two runs on three hits, denying him the victory because he only went 4 2-3 innings.
Clint Barmes led off the inning with a double and scored on Seth Smith's single. Tulowitzki chased Stauffer with an RBI single that made it 6-2.
Webb walked Brad Hawpe, loading the bases, but got Yorvit Torrealba to ground out to second to end the inning.
The Rockies pulled to 6-3 on Todd Helton's sacrifice fly off lefty Joe Thatcher in the seventh.
Notes: Game time temperature was 48 degrees. ... The Rockies will soon have reliever Alan Embree pitch in the Arizona instructional league. He's been out with a broken right leg since he was struck by a line drive off the bat of Atlanta's Martin Prado on July 10. ... The Rockies kept LF Carlos Gonzalez out of the lineup because his left hamstring grabbed on him Tuesday night. ... Colorado reliever Manny Corpas (elbow spurs) will pitch in the Arizona instructional league soon and Tracy wouldn't rule out his return this month or next.
