SAN DIEGO -- The D-backs ended Heath Bell's consecutive saves streak, but they could not put a stop to their struggles at PETCO Park as they fell to the Padres, 4-3, in 11 innings on Friday night.
The loss was Arizona's eighth in its last nine games at PETCO, and the D-backs are 24-41 all-time here.
Chase Headley ended things by drawing a bases-loaded walk off Sam Demel (1-2) that scored Chris Denorfia.
"It was a great at-bat," Demel said of the eight-pitch matchup in which he jumped ahead 1-2. "He battled me the whole way. I made some really good pitches and then I tried to throw one that started down the middle and it just took off on me."
With one out in the 11th, Denorfia legged out an infield hit, moved to second on Will Venable's single to left and to third on a Jason Bartlett groundout. Just prior to Headley's walk, Ryan Ludwick was awarded first base due to catcher's interference when his bat touched Miguel Montero's glove while fouling a pitch off.
"Did it hit me?" Montero said. "I didn't feel it. [Home-plate umpire Derryl Cousins] said, 'I heard something.' If I had felt it, I would have shaken my hand or something. Plus, he's too far out of the box to reach. Regardless, you've got to feel it. It's a swing on your hand. At least it would have moved my glove, and I don't think it even moved it. I'm going to [look at the replay]. If it did hit me, what, was it a plastic bat? Because I didn't feel it."
Down, 3-0, heading into the ninth with Bell looking for his 42nd consecutive save, which would have set a Padres record, the D-backs staged a tying rally.
Ryan Roberts and Juan Miranda began it by drawing back-to-back walks and Gerardo Parra followed with an RBI double to cut the lead to 3-1.
Bell then settled down to fan pinch-hitter Russell Branyan and Chris Young.
Kelly Johnson then hit a grounder to third that Headley fielded cleanly. Headley's throw was low and first baseman Brad Hawpe could not scoop it, allowing Miranda to score from third and Parra to come around from second to tie the game.
That they ended Bell's streak was of little consolation to Arizona manager Kirk Gibson, who was steaming from the 10 walks his team allowed, six by starter Armando Galarraga.
"There's no satisfaction in that at all," Gibson said. "We lost the game. We walked nine guys, we walked the winning run in. I said going in you can't walk guys in this ballpark. Armando had six walks. We had to intentionally walk a guy because he walked the first two guys of the inning. They're an aggressive team and you're playing right into their hands. So overall we didn't deserve to win the game today."
Arizona pitchers were behind throughout the game as they went to three balls on San Diego hitters a whopping 19 times.
"That's terrible, just terrible," Gibson said. "You've got to be better than that. I don't know what else to say."
The Padres took a lead in the third as they capitalized on Johnson's error to score two runs, only one of which was earned.
That was plenty of support for Padres starter Tim Stauffer, who cruised through the game's first six innings, holding the D-backs to just two singles and a double over that stretch.
"He was just really locating with his fastball," Padres catcher Rob Johnson said. "He's got the hitters off-balance with his off-speed stuff and then he was dotting his fastball."
By contrast, Galarraga matched a career high in walks before being replaced with one out in the fifth.
"He couldn't get ahead in the count and it's tough to get out of jams like that," Montero said.
