ATLANTA – Justin Upton hit a two-run homer, Chris Johnson also went deep and the Atlanta Braves beat Jon Lester and the reeling Oakland Athletics 4-3 on Sunday night, ending Lester's seven-game winning streak.

The Braves swept the three-game series, leaving the A's with a five-game losing streak, their longest of the season. The A's have lost seven of eight overall and trail the Angels, who lost to Texas on Sunday, by percentage points in the AL West.

Oakland's Nate Freiman hit two homers, giving him three in the series, but Mike Minor (5-8) allowed only two other hits in seven strong innings.

Lester (13-8) allowed four runs, three earned, and six hits in six-plus innings in his first loss since June 7 for the Red Sox at Detroit.
