OAKLAND, Calif. -- Oakland needed a big hit in the 10th inning against Philadelphia. Fortunately for the Athletics, they had Josh Donaldson at the plate.
Donaldson hit a two-run homer to lift the A's to an 8-6 victory over the Phillies on Sunday.
"Those are the moments I always want to be in," Donaldson said after his third game-ending homer of the year, matching, among others, Hall of Famer Reggie Jackson for the franchise mark in a season.
"He's a tough customer in big at-bats," A's manager Bob Melvin said. "He embraces it."
Sean Doolittle (2-4) pitched two innings for the victory, striking out four. It was the closer's longest outing since he recorded four outs at Seattle on July 13.
Geovany Soto drove in three runs for the A's, who have won two of three to remain atop the AL wild-card race.
Marlon Byrd drove in three runs for the Phillies, who have lost six of eight.
A's starter Scott Kazmir was charged with six runs and 11 hits in 5⅓ innings. Since Aug. 3, Kazmir has an ERA of 6.67. It was at 2.37 through July.
A.J. Burnett lasted just 4⅓ innings for Philadelphia. He walked six and allowed six runs and three hits.
Burnett also struck out three, tying him with Charlie Hough for 43rd on the career strikeout list with 3,360. Sandy Koufax is next at 2,362.
"I didn't get anything done today, man. It's very frustrating," Burnett said. "I didn't make any pitches from the get-go. It's embarrassing."
Soto recorded his first three-RBI game since July 30 of last year, walking with the bases loaded in the third and doubling home two runs in the fifth. Josh Reddick, Brandon Moss and Adam Dunn also drove in runs for the A's.
Phillies: OF Domonic Brown, who hurt his right wrist on Thursday and was scratched from Friday's lineup, hopes to return when the Phillies open a series in Miami on Tuesday. ... INF Jimmy Rollins (strained left hamstring) was hoping to return to action in his hometown of Oakland but now hopes just to make another appearance this season. Manager Ryne Sandberg would not say one way or the other about Rollins' status for the rest of the year.
Athletics: OF Craig Gentry (concussion) and C John Jaso (concussion) are still not able to participate in baseball activities. `'He's still having a little bit of a tough time with it," A's manager Bob Melvin said of Gentry. "I think yesterday he went and saw another doctor. I haven't heard anything yet." Melvin added. "With eight games left, there's always that possibility" he'll miss the rest of the season. "Same thing, obviously, with Jaso," he said. ... INF Jed Lowrie left with a left foot contusion, the result of a hit by pitch in the first inning.
Phillies: Following an off day Monday, LHP Cole Hamels (9-7, 2.47 ERA) gets the nod in Tuesday's series opener at Miami. He's starting his fifth game against the Marlins this year and will be looking for his first win. He is 9-13 with a 3.19 ERA against the Marlins for his career.
Athletics: RHP Jeff Samardzija (4-5, 3.13 ERA) makes his third career start against the Los Angeles Angels on Monday night. He is 0-2 with a 7.11 ERA against them. OF Jonny Gomes is a lifetime .318 hitter (7-for-22 with three extra-base hits and six walks) against Angels starter C.J. Wilson.
