PHILADELPHIA (AP) Carlos Santana homered and drove in four, Cesar Hernandez had a two-run double and the Philadelphia Phillies overcame a four-run first-inning deficit to beat the San Diego Padres 11-5 on Friday night.
Odubel Herrera added two RBIs for the surprising Phillies, who remained a half-game ahead of Atlanta for first in the NL East with their 13th win in 19 games.
Austin Davis (1-0) got his first major league win with 1 2/3 scoreless innings in relief of Jake Arrieta. Davis was one of five Phillies relievers who combined to allow just three hits over 5 2/3 scoreless innings.
Freddy Galvis had three hits, including a double, and drove in two runs in his return to Philadelphia for the Padres. Galvis played his first six seasons with the Phillies before being traded in the offseason.
Clayton Richard (7-9) allowed seven runs and four hits in three innings for the last-place Padres, who have lost six straight and 22 of 28.
San Diego got off to a promising start against Arrieta. The former NL Cy Young Award winner stumbled in the first inning when San Diego scored four runs on three hits and was helped by two errors - one on Arrieta - and a wild pitch.
Arrieta had been 2-0 with a 1.89 ERA in his last three starts, but he labored through a 35-pitch opening frame.
Philadelphia got a run back in the bottom of the first before exploding for six runs in the second to go in front for good. Santana had the big blow with a three-run shot to left field. The Phillies also got an RBI walk from Rhys Hoskins and a two-run single from Hernandez.
Arrieta allowed six runs - five earned - in 3 1/3 innings with two strikeouts and three walks.
Padres: CF Manuel Margot left with two outs in the eighth inning after getting injured while diving for Hernandez's double. Margot appeared to hurt his left wrist.
Phillies: OF Roman Quinn had a hit for Class A Clearwater on Friday in his first game since surgery on his right middle finger on May 21. Once a top Phillies prospect, Quinn has been besieged by injuries in his career.
RHP Luis Perdomo (1-4, 7.55) pitches for the Padres in the second game of the three-game set on Saturday afternoon against Phillies RHP Vince Velasquez (5-8, 4.39).
