SAN DIEGO --- Orlando Hudson didn't lose the game with one play. He just personified it.
The Padres' second baseman made a running catch in shallow right field in Tuesday's sixth inning and tossed the ball to a ball girl to give to a fan.
But there were two outs, not three.
By rule, the runners on first and second each advanced two bases because of the error, scoring Chris Young to give Arizona a four-run advantage in the sixth inning -- a margin that turned into a 6-1 D-backs victory before 22,679 at PETCO Park.
"I knew what the rule was, so I saw him run over to the stands and I was thinking, 'What's he doing?'" said Arizona manager Kirk Gibson. "I think the greatest thing is, did the fan throw it back to him? Not right away, but he threw it back, but that's two bases. That was fortunate for us."
A strange play, in a strange game, but Hudson said he just laughed it off when he did it.
"'Well, there's only two outs. I threw the ball away, let's get the third out. My bad boys,'" Hudson said. "It happens. That's all I can say. And then I started laughing."
Hudson's catch -- though it cost the Padres (45-59) a run -- was just part of the fraying.
In the third inning, Padres starting pitcher Dustin Moseley hit a line-drive single to right field but dislocated his left shoulder and fell to the ground in the batter's box -- the same shoulder he dislocated earlier this season.
But instead of it forcing an early end to his outing, the shoulder popped back into the socket when Moseley fell to the ground, and the pitcher made it to first base.
"When a guy falls down in the batter's box and he's holding his shoulder, you're thinking he's out of the game," said Padres manager Bud Black. "When he got to first base, he said, 'Buddy, I'm fine. It popped back in.'"
Moseley (3-10) ended up pitching seven innings and surrendered five runs (four earned) on seven hits, not nearly the effort he needed to keep pace with Arizona starting pitcher Joe Saunders.
Saunders (7-8) almost pitched a shutout, and would have, if it weren't for a home run hit by Jesus Guzman to left-center field with two outs in the bottom of the ninth.
Instead, Saunders went nine innings and gave up the one run on six hits. The Padres worked just two baserunners into scoring position against the lefty.
"It's no fun to lose a shutout, but he kind of ambushed me there, and you live and you learn," Saunders said. "Next time it's going to be a different pitch, you never know."
Shutout or not, Saunders had plenty of security behind him.
The D-backs scored two runs in the third inning, prompted by Willie Bloomquist's one-out single to right field, and he scored when Kelly Johnson hit a triple to the right-center-field gap. A sacrifice fly to center field by Justin Upton put Arizona up by two runs.
"You know, they bunched some hits together, and we didn't," Black said. "That's key."
Upton struck again in the sixth inning with a solo home run to left-center field, and Hudson's error had the score at 4-0 by the end of the sixth inning.
Bloomquist scored another run in the seventh when his two-out double was followed by Johnson's RBI single to center field.
San Diego relief pitcher Pat Neshek walked four of the seven batters he faced in the ninth inning as the D-backs picked up a sixth run.
It was, in a sense, an unusual day of baseball.
Moseley's injury wasn't the only abnormal part of the game, but it wasn't even the only abnormal injury. Catcher Rob Johnson bruised his right hand in the seventh inning.
He wasn't sure how he left his throwing hand exposed, but the impact of the ball left him in a good deal of pain and he had to leave the game.
"Man, it just hurts," Johnson said. "I couldn't throw the ball. I was done. With Bloomquist coming up, if he chops the ball in front of the plate, I'd have no chance."
While the repercussions of Johnson's injury are unknown, Moseley's prospects are much brighter.
He expects to make his next scheduled start.
"I should be OK," Moseley said.
