SAN DIEGO (AP) -- The New York Mets took advantage of Edinson Volquez's wildness to get the win.
Jeremy Hefner pitched a strong game against his former team and the New York Mets earned a 6-2 victory over the San Diego Padres on Saturday night.
But the Mets didn't make it easy as they stranded 13 base runners and went 3 for 15 with runners in scoring position.
Then when Bobby Parnell faltered in the ninth inning, New York called upon closer Frank Francisco for his first action since coming off the disabled list on Friday.
''We are sitting there in the dugout in the ninth inning and thinking we ought to have 10 runs and we don't,'' Mets manager Terry Collins said. ''We left way too many guys on base again. It was a game we were fortunate to win, but we need to start driving some of those runs in.''
In Wednesday night's 2-1 win at San Francisco, the Mets loaded the bases in each of the final three innings and came away scoreless. They went 1 for 13 with runners in scoring position and left 13 runners on base.
Fortunately for the Mets on Saturday, Volquez's lack of control led to two bases loaded-walks and a four-run second that gave the Mets an early cushion.
Hefner (2-4) made the runs stand up as he made his third start in place of the injured Johan Santana his most impressive one.
The right-hander held San Diego to one run and five hits with no walks and two strikeouts.
''I hope he (Collins) knows I can compete and that I'm going to give him 100 percent every time,'' said Hefner, who is likely to get bumped from the rotation once Santana returns.
Hefner gave up three hits to Alexi Amarista, who also had an RBI, and two to Everth Cabrera.
''He's in the strike zone and he makes you swing the bat,'' Collins said. ''He doesn't beat himself by walking guys. He really has done a nice job.''
Volquez (7-8) allowed four runs and two hits in 1 2-3 innings. The right-hander walked four, including the two with the bases loaded. Volquez has walked a major league-high 84.
''You see those hitters at the plate and you try to do too much, more than you can,'' said Volquez, who said he got a blister on his right thumb in the first inning.
''I couldn't feel the ball very well,'' he said. ''It's a tough day. Everybody can have a day like that in the big leagues.''
New York's Mike Baxter tied an overall club record with five walks. He set the Mets' record for a nine-inning game. The Mets walked 10 times overall in the win.
Josh Thole drove in two runs for the Mets, who have won five of seven and are 6-4 on their season-high, 11-game West Coast road trip. Daniel Murphy tied his career high with four hits.
Holding a 6-1 lead in the ninth, Parnell's first pitch went for a Chase Headley home run, his 14th. Parnell then allowed a one-out double to Yonder Alonso and walked Cameron Maybin to bring on Francisco.
The big right-hander made just two pitches to get John Baker to hit into a game-ending double play. It was Francisco's 19th save in 22 chances.
After a solid first inning, Volquez got wild in the second. After Ike Davis' leadoff single, Volquez issued consecutive walks to load the bases. The right-hander struck out Andres Torres before he missed on a full-count pitch to Thole to force in a run.
After Volquez struck out Hefner, he walked in a second run when he missed again on another full-count pitch to Ruben Tejada. Jordany Valdespin then lined a two-run double to right field to knock Volquez out of the game.
''His mechanics were out of whack, as much as I've seen him this season,'' San Diego manager Bud Black said.
Hefner, drafted by San Diego in the 10th round in 2007, was pounded by the Padres in his first major league start May 24. He allowed six runs and nine hits before getting pulled with two outs in the fourth in an 11-5 defeat.
