PHILADELPHIA -- The final ball that San Diego catcher Austin Hedges hit on Friday night didn't leave Citizens Bank Park like the first two did.

It was plenty good enough, though, as Hedges' sacrifice fly in the ninth inning lifted the Padres to a 4-3 win over the Philadelphia Phillies on a rainy Friday night at Citizens Bank Park.

Despite coming through with the game-winning RBI, Hedges afterward was lamenting the fact he didn't do what he was originally supposed to -- lay down a suicide squeeze to try and drive the winning run home.

Instead of getting the bunt in play, Hedges whiffed on the first two attempts, forcing him to get it done a different way.

"I should have gotten the safety squeeze down. I would have been a lot more excited about it -- well, that's false, I was excited about the sac fly," he said. "Obviously, I wish I got the sac (bunt) down but to still go out and win the at-bat, that's tough to do after you screw up what you're supposed to."

The sacrifice fly capped off a powerful offensive night for Hedges, who earlier hit two solo home runs for his first multi-homer game in the major leagues.

It was the last at-bat that most impressed his manager, however.

"You've got a strikeout pitcher on the mound with a very good split and a very good high fastball and if you're evaluating where (Hedges') strengths and weaknesses reside, that's not the greatest matchup," Padres manager Andy Green said. "Which is great credit to him that even with two strikes he managed to get the job done today. That was a great job after not getting the safety squeeze down."

A 94-minute rain delay midway through the seventh inning helped the Phillies get right back into a game they had trailed to that point.

San Diego starter Clayton Richard had limited his opponents to five hits and one run in six innings before the storm forced the Padres to go to the bullpen.

"He was outstanding," Hedges said. "First couple of innings he was on point, he was as good as he's been, and he lost a little bit of command later but he's such a good competitor that we made an adjustment and he was able to give us six great innings."

The Phillies put runners on second and third against reliever Phil Maton, and pinch-hitting Daniel Nava made it a one-run game with a ground ball to the mound.

Freddy Galvis then tied it up with a single through the gap at short off left-hander Brad Hand, scoring rookie outfielder Nick Williams, who had doubled in a pinch-hitting appearance.

Hand (2-4), the Padres' only All-Star selection, ran into more trouble in the eighth, walking Tommy Joseph and giving up a single to Odubel Herrera to put men on first and second with one out. But he struck out Andres Blanco and Cameron Rupp to end the inning.

San Diego got to Phillies reliever Hector Neris (2-3) immediately thereafter. Cory Spangenberg singled and advanced to third on a one-out base hit by Carlos Asuaje before Hedges brought him home with a fly ball to center.

Brandon Mauer pitched a perfect ninth inning for his 18th save of the year.

"Very resilient from our group of guys," Green said. "I know we've had our fair share of getting blown out, but when it's close our guys have figured out a way to win the game."

Hedges, who had missed the two previous games with some neck tightness, had the Padres in good shape before the delay. A solo shot to left in the third inning put the Padres up 2-0 and his follow-up at-bat in the fifth inning ended the same way, with Hedges rounding the bases after the ball landed in the right-field seats to make it 3-1.

"It was good to see him swing the bat well," Green said. "He's been working hard in the cage. He's been kind of scuffling a bit lately. I'm sure the two days (off) helped him reboot the system, too."

Hedges wasn't the only Padres' hitter to go deep against Phillies starter Nick Pivetta. Jose Pirela got the scoring underway in the first inning with a homer to left, his fourth of the season.

Philadelphia's first run also came on a solo shot, off the bat of Joseph in the fourth inning. That was the 15th of the season for the first baseman, who hit 21 in 107 games as a rookie last year.

"Still some things I'm working on," Joseph said, "but I've done a better job of putting the ball in the air, which helps with extra-base hits."

The home runs were the only problem for Pivetta, who went seven strong innings, giving up five hits while striking out nine Padres along the way.

"I'll take three solo shots over walking anybody," he said. "I'm finding my consistency and keep moving forward."
