SAN DIEGO -- Xavier Nady woke up Thursday morning with a 103-degree fever and headed to an urgent-care facility to get some antibiotics.
Nady didn't get to the ballpark until about an hour before the first pitch. He was held out of the starting lineup but the Padres figured he'd at least be well enough to pinch-hit.
"The way the game was going, it obviously changed a few things," Nady said. "You always want to be in there. From the start, I don't know if that would have been in the team's best interest the way I was feeling, if I would have been productive or not.
"It's fun to be in there and to help out. I'm still kind of just dripping sweat. I can't get over it."
Nady, who started in center field in San Diego's first two games, started feeling ill Wednesday night after a win at Colorado. He came in to play center in the 10th and popped up weakly to the catcher that inning with runners on first and second.
In the 12th, he drew four consecutive balls from Rick White (0-1).
The Padres received a jolt when Eric Young separated his right shoulder making a catch against the center-field fence in the first.
Young appeared to jam his arm against the wall as he made a leaping catch of Jason Bay's drive for the third out. He grimaced as he stayed on the ground for a few moments, then held his shoulder as he stood up.
Assistant trainer Jim Daniel helped immobilize Young's arm as they walked off the field.
Young was starting in place of Nady, who started the first two games in center because Dave Roberts is on the disabled list with a strained groin.
Young is scheduled to have an MRI on Friday.
He had been penciled in as the Padres' third leadoff batter in three games. Adam Hyzdu pinch-hit for Young and replaced him in center.
Pinch-hitter Geoff Blum started the winning rally with a single off the top of shortstop Freddy Sanchez's glove and went to second on Ramon Hernandez's single. Both advanced on Khalil Greene's sacrifice bunt. Sean Burroughs was intentionally walked to load the bases.
The Pirates, who struck out 15 times, dropped to 0-3.
Pittsburgh loaded the bases with three singles against Akinori Otsuka in the 11th before Rudy Seanez (1-0) came on and struck out Chris Duffy, who was playing in his first big league game after being recalled from Triple-A Indianapolis earlier in the day when infielder Jose Castillo was put on the disabled list.
Seanez struck out three in 1 1/3 innings.
Hits were scarce on a cool, breezy evening at Petco Park.
San Diego starter Jake Peavy had a great start on defending his major-league ERA title, striking out 10 and holding the Pirates to four hits in 6 2/3 innings. Last year, the 23-year-old Peavy became the first Padres pitcher to lead the majors in ERA, at 2.27.
Left-handed Mark Redman, who grew up in nearby Escondido and was making his Pirates debut, held the Padres to four hits in six innings. He struck out three and walked one.
"You're matching up against an excellent pitcher with Jake Peavy," Pittsburgh manager Lloyd McClendon said. "If you can keep inning by inning with him, you're doing all right."
Redman had a 7.04 ERA in the spring.
"When the light comes on, those guys are ready to pitch," McClendon said.
Peavy was replaced by Scott Linebrink after issuing his second walk, to Sanchez with two outs in the seventh to put runners on first and second. Linebrink induced pinch-hitter Daryle Ward to hit into a force.
The Padres twice advanced runners to third while Peavy was still in the game, but couldn't bring them in.
Peavy reached third in the sixth before Brian Giles hit into an inning-ending double play. Giles reached third with one out in the fourth, on a double and a wild pitch, but Phil Nevin and Ryan Klesko struck out.
- Until Thursday, Redman had faced every major-league team except the Padres.
- Redman is the brother-in-law of Padres pitcher Brian Lawrence.
- Pirates SS Jack Wilson was scratched after batting practice and replaced by Sanchez. Wilson was hit by a pitch on the left hand in the eighth inning of Wednesday's loss to Milwaukee.
- Hyzdu made a diving catch of Craig Wilson's slicing liner in the second.
