SAN DIEGO (AP) _ Damian Jackson's tiebreaking double was one of four extra-base hits in the seventh inning for the San Diego Padres, who blew a five-run lead and then rallied to beat the Milwaukee Brewers 9-5 Wednesday night.

The Padres won their third straight series to finish the homestand 7-2. They went 2-1 against the Brewers and the New York Mets, and swept Montreal.

David Weathers (3-2) allowed doubles by Carlos Hernandez, Jackson and pinch-hitter Dave Magadan opening the seventh, then was chased by Rivera's two-run triple.

The Padres drew 12 walks, three intentional, to tie the club record for a nine-inning game. It was the third time they've had that many, first since Sept. 7, 1980, against San Francisco. The 12 walks were two short of the Brewers' record, set April 29 against Houston.

After Hernandez doubled to the left-center gap, Jackson followed with a double to right that hit a divot and took an odd hop past Jeromy Burnitz, allowing Hernandez to score the go-ahead run.

Carlos Almanzar (1-1) faced one batter for the win, getting Jose Hernandez to ground into a force play to end the seventh with the bases loaded.

Milwaukee's Geoff Jenkins went 4-for-4 _ all singles _ to tie his career high, drove in a run and scored once.

Rodrigo Lopez was trying to become the second San Diego pitcher in as many nights to get his first major league victory, but once again was burned by his bullpen.

The 24-year-old Lopez was making his fourth big league start. In his debut on April 29 against Atlanta, he left with a 4-1 lead after seven innings, only to watch the bullpen blow the lead and the game as the Padres lost 7-4 in 12 innings.

The Padres scored four runs in the fifth to stake Lopez to a 5-0 lead. Milwaukee came back with four in the sixth, the first three allowed by Lopez, and reliever Brian Boehringer then allowed a tying homer by the first batter he faced, Raul Casanova, leading off the seventh.

Casanova, a former Padres farmhand, homered to right on a 3-2 fastball. It was his first homer since July 16, 1998, against the New York Yankees while he was with Detroit.

On Tuesday night, San Diego's Adam Eaton beat Milwaukee 6-3 in his major league debut.

The Padres led 1-0 going into the fifth inning, when they scored four runs on three hits and three walks. After leadoff batter Eric Owens lined out to second, six straight Padres reached base. Phil Nevin had an RBI single and Ryan Klesko an RBI double before Bret Boone walked to load the bases and chase Snyder.

Steve Woodard came on and walked Hernandez on four straight pitches to force in a run, and Damian Jackson hit a sacrifice fly to make it 5-0.

Jenkins' RBI single in the sixth chased Lopez, and reliever Matt Whiteside allowed Jose Hernandez's RBI fielder's choice and Marquis Grissom's two-run double to pull the Brewers to 5-4.

Milwaukee starter John Snyder walked seven and allowed five runs _ four earned _ on four hits. He struck out two.
