SAN DIEGO – Jake Peavy regained his form, holding the Florida Marlins to one run and five hits in seven innings and leading the San Diego Padres to a 2-1 victory.

The Padres won for the 12th time in 15 games, overcoming a combined three-hitter by Al Leiter and John Riedling. Trevor Hoffman threw four pitches in a perfect ninth for his 404th career save, and his 11th in 13 chances this year.

Padres pitchers retired the last 12 batters in a row.

Peavy (3-0), last year’s major league ERA champ at 2.27, had gotten four straight no-decisions, a span that saw him allow an uncharacteristically high number of earned runs. Peavy rarely has allowed more than two earned runs in a start, but did it in each of his last three outings, a total of 11 in 21 1-3 innings.

After escaping a bases-loaded jam in the fourth inning, Peavy allowed the Marlins to close to 2-1 in the sixth on Mike Lowell’s sacrifice fly. That brought up Carlos Delgado, who hit a leadoff double in the gap in left-center and advanced on Miguel Cabrera’s groundout.

Peavy struck out eight and walked one.

San Diego took a 2-0 lead in the second off Leiter (1-4).

With Phil Nevin aboard on a leadoff walk, Brian Giles hit what looked like should been a two-run home run but ended up with a ground-rule double. His fly ball landed on top of the auxiliary scoreboard on the right field wall and bounced back onto the field. Manager Bruce Bochy argued unsuccessfully to get the call overturned.

Both ended up scoring, though; Nevin on Ramon Hernandez’s single that bounced off Leiter’s right foot and Giles on Khalil Greene’s sacrifice fly.

Leiter allowed two runs and three hits in six innings, walked five and struck out three.

Notes: The Marlins’ 2-7 record in one-run games is the worst in the NL. … Florida’s A.J. Burnett is scheduled to start Sunday against the Padres for the first time since his nine-walk no-hitter at San Diego on May 12, 2001. … The San Diego Chicken made his Petco Park debut. … Padres INF Geoff Blum, on the disabled list with a bruised chest since April 30, will begin a three-day rehab assignment at Class A Lake Elsinore on Monday and is due to rejoin the big league team when it starts a road trip next Friday at Seattle.
