SAN FRANCISCO -- San Diego Padres right-hander Ian Kennedy admitted to feeling extra pressure before his first pitch Wednesday afternoon against the San Francisco Giants.

Because his team had gotten shut out the first two games of the series? Actually, no.

Rather, because he didn't want to mess up catcher Austin Hedges' starting debut.

Kennedy allowed only one run in seven innings and Hedges contributed to a 16-hit attack with his first major league hit and first two RBIs, helping the Padres rebound from consecutive shutout losses with 9-1 win over the Giants in the finale of a three-game series.

"He was great. He was really nice to throw to," Kennedy said of Hedges, the San Diego organization's No. 2 prospect who was promoted from the minors on Monday. "I wanted to pitch well for his first game."

That he did. Kennedy helped San Diego end the two-game losing streak with seven innings of six-hit pitching, pushing the Padres (15-14) back ahead of the Giants (14-14) in the National League West standings.

Upon hearing Kennedy's remark about being nervous for the rookie's big day, Hedges said, "Shows you what kind of guy he is. He pitched his butt off. He made my job easy. I just put a finger down and caught it."

Coming off 2-0 and 6-0 wins the previous two nights, the Giants had been seeking a sixth consecutive win and a third straight series sweep.

"We had been playing well," Giants manager Bruce Bochy said. "You're going to have games like this."

The Padres' scoreless streak, which began in the seventh inning of an 8-6 win over Colorado on Sunday, reached 22 before right fielder Matt Kemp's double scored third baseman Cory Spangenberg to ignite a five-run third inning against Giants right-hander Chris Heston.

San Diego, which leads the National League in scoring, also had a 22-inning scoreless stretch in April.

"We were due," Padres manager Bud Black said. "(Left-hander Madison) Bumgarner shut us down, and (righty Ryan) Vogelsong pitched well. Our guys were disappointed. They came out with an edge and everyone contributed."

First baseman Yonder Alonso, second baseman Jedd Gyorko, shortstop Alexi Amarista and Hedges capped the Padres' third inning with consecutive RBI singles. San Diego had six hits in the inning after totaling just six in the first two games of the series.

Hedges' hit, a hard grounder up the middle, was the first of his career.

"For me, (the highlight of the day was) working with the pitchers and contributing to the win," said Hedges, who was bathed in a collection of beer, powder and shaving cream after the game. "We're going to score runs."

Spangenberg, Amarista and center fielder Wil Myers had three hits apiece for the Padres. Gyorko, Amarista and Hedges each drove in a pair of runs.

Left fielder Justin Upton was the only Padres starter without a hit, but he did walk a career-high four times and score twice.

Myers had an RBI triple for the Padres, increasing their lead to 6-1 in the seventh inning, and Gyorko's run-scoring double highlighted a three-run eighth against the San Francisco bullpen.

"You hope that happens," Kennedy said of the offensive support. "I don't see our lineup getting shut out too often. We have that fire. We don't like getting shut out."

Kennedy (2-1) recorded his 10th career win against the Giants. He struck out five and did not allow a walk in seven innings.

The Giants' lone run came in the third inning on a single by left fielder Nori Aoki, scoring third baseman Matt Duffy.

Duffy had two of the Giants' six hits. First baseman Brandon Belt added a double and a triple.

Heston (2-3) was pulled after five innings, having allowed five runs on a season-worst-tying 11 hits. He walked three and struck out four.

"They were hitting the ball the other way really hard," Heston said. "I need to command the inside part of the plate a little better to combat what they were doing."

Giants pitchers had allowed no runs and four or fewer hits in three straight games, a franchise-best streak.
