SAN DIEGO - Rookie Jesse Hahn pitched seven strong innings and pinch-hitter Chris Denorifa singled in the go-ahead run in a four-run seventh for the San Diego Padres, who rallied for the second straight game to beat the Seattle Mariners 4-1 on Thursday.

The light-hitting Padres salvaged a split of the four-game season series by winning consecutive games for the first time since May 30-31. Robinson Cano had three singles for the Mariners, who beat the Padres in Seattle on Monday and Tuesday.

Hahn (2-1) was making his third big league start. He held Seattle to an unearned run and five hits, struck out seven and walked two. In his last two starts, Hahn has allowed no earned runs and just six hits while striking out 14 in 13 innings.

Huston Street pitched the ninth for his 20th save in 20 opportunities, getting a double-play ball after allowing a double and single with one out.

Seattle's Erasmo Ramirez, winless since April 1, left with a 1-0 lead after six innings. But Dominic Leone (2-1) allowed runs, three hits and a walk while getting only one out in the seventh.

Yasmani Grandal grounded out leading off the Padres' seventh before they tied it on consecutive triples by Tommy Medica and Cameron Maybin. On Wednesday night, Medica's RBI pinch-hit single in the eighth gave the Padres a 2-1 win.

Carlos Quentin walked and was replaced by pinch-runner Jace Peterson before Denorfia, pinch-hitting for Hahn, singled to centre to bring in Maybin with the go-ahead run. Joe Beimel came on and retired Will Venable before allowing Everth Cabrera's two-run single to right.

Ramirez held San Diego to two hits while striking out three and walking two.

Cano drove in Seattle's only run with his second single off Hahn, in the fifth. Cano extended his road hitting streak to 20 games. Brad Miller drew a leadoff walk and was safe at second on Endy Chavez's one-out grounder after Cabrera, the shortstop, dropped the ball for an error. Miller scored on Cano's single to right-centre.

NOTES: The Padres placed 1B Yonder Alonso on the 15-day DL, retroactive to Tuesday, with tendinitis in his right wrist. ... To take his place on the roster, OF Jake Goebbert was selected from Triple-A El Paso. Goebbert is still waiting to make his big league debut. He was in the on-deck circle in the seventh but was pulled back for Denorfia. He was acquired from Oakland on May 15 in the deal that sent Kyle Blanks to Oakland. ... Padres 2B Jedd Gyorko had his left foot put back into a cast and walking boot. He had removed them recently as he battles plantar fasciitis. "It's not a good sign," manager Bud Black said. "But hopefully it helps."... The Padres open a three-game series against the Los Angeles Dodgers on Friday night, when RHP Dan Haren (7-4, 3.54 ERA) is scheduled to face RHP Ian Kennedy (5-8, 3.72). ... The Mariners head to Kansas City where they open a three-game series Friday, with RHP Hisashi Iwakuma (5-3, 2.59) scheduled to oppose RHP James Shields (8-3, 3.50).
