The Dodgers got three hits each -- including home runs -- from Juan Uribe and Adrian Gonzalez. But Gonzalez also committed an error at first bae that led to a pair of unearned runs in the fifth inning.
And the bullpen took another loss, its seventh of the 10 Dodgers losses this year.
The postgame questions to manager Don Mattingly focused on Wilson, who allowed only one run in 18 appearances last year. If the reliever is hurting, as he was during Spring Training and again at the end of last month with an irritated ulnar nerve, Mattingly isn't aware.
"We feel like he's healthy," said Mattingly. "Obviously, his location is not where he wants it. This guy barely misses his spots at all."
In the ninth inning, Wilson allowed a leadoff single to Cody Asche, a one-out single to Ben Revere, a two-run double to Carlos Ruiz, an intentional walk to Chase Utley and then hit slumping Ryan Howard with a pitch before he was removed.
"The only thing we can do is ask," Mattingly said of Wilson, who conceded a month ago that he tried to compensate for lack of arm strength after a compressed Spring Training by muscling up with his pitches, only to irritate his twice-repaired elbow.
"We think it's a matter of not executing. That's where we start if nothing is wrong physically. We have to make sure he's being honest and he feels good. We know if Brian is throwing the way he's capable of, it makes us pretty strong."
Because Kenley Jansen had pitched five of the six preceding days, Wilson was Mattingly's closer for this game, which is why he took over in the ninth with the score tied, 3-3. Mattingly mentioned Chris Withrow and Chris Perez, each having pitched a scoreless inning in this game, as potential replacements for Wilson if it comes to that, but the manager said that decision hasn't been made.
Ruiz's double was his second of the game and sixth extra-base hit of the four-game series. The Phillies won three of the four, Ruiz going 0-for-3 in their only loss. Marlon Byrd helped in this win with four RBIs. Ruiz and Byrd had three hits each.
Dan Haren started for the Dodgers and struck out seven in a six-inning no-decision, charged with three runs, one earned.
The Dodgers had two-out singles in each of the first three innings without scoring off Kyle Kendrick. In the fourth, Gonzalez led off with a double. Yasiel Puig, who slammed his left shoulder into the box-seat padding chasing Byrd's foul ball in the third inning, bounced out to third. Andre Ethier struck out before Uribe hit his towering shot for a 2-0 lead.
Philadelphia came back with three runs in the top of the fifth when it executed and the Dodgers didn't. After a one-out single by Revere, Ruiz sent a perfect hit-and-run single into the hole that shortstop Hanley Ramirez vacated to cover second base. Utley sent a bouncer to Gonzalez, but he booted it as Revere scored.
"I realized I couldn't get two and took my eye off the ball to see if I had a play at home," said Gonzalez. "It would have been a bang-bang play at home, but I've got to make sure I catch the ball first, then look."
Howard's grounder back to Haren moved the runners over and Byrd brought them home with a double that barely eluded the laid-out dive of Puig in right-center for a 3-2 Philly lead.
The Dodgers had a chance to respond in the bottom of the fifth, putting runners on first and third with one out on singles by Ramirez and Gonzalez. Puig bounced over the bag to third baseman Asche, who flipped home ahead of Ramirez, standing up as he was tagged out by catcher Ruiz.
Mattingly argued that Ruiz blocked the plate in violation of the new rule designed to avoid home-plate collisions, but the call was confirmed after a crew-chief review for the second out and Ethier grounded to first to end the threat.
In the bottom of the sixth, Uribe was safe at first on a leadoff infield single that would stand after a replay challenge by the Phillies. With two outs, Dee Gordon singled Uribe to second. Jake Diekman relieved and faced pinch-hitter Matt Kemp, who struck out.
Mike Adams took over for the Phillies and allowed Gonzalez's sixth home run with one out in the bottom of the seventh to tie the game at 3-3 and take Haren off the hook.
