ATLANTA (AP) — A year after a 9-0 record in Atlanta helped give Philadelphia momentum for its World Series championship run, three straight losses at Turner Field left the Phillies feeling flawed.

Matt Diaz drove in the go-ahead run with an eighth-inning double and the Braves beat Philadelphia 5-2 on Thursday night to complete their first home sweep of the Phillies in four years.

Diaz had his second straight three-hit game to lift the Braves to their fourth consecutive win. The Phillies are less than a percentage point ahead of Florida, .5131 to .5125, for first in the NL East.

“We need to turn it around at some point,” said first baseman Ryan Howard of the reeling Phillies, who have lost 12 of 15 to fall only two games over .500 and two games ahead of the fourth-place Braves.

“We’re just not playing good ball right now, plain and simple,” Howard said.

The Braves, who failed to beat the Phillies at Turner Field last season, completed their first home sweep of Philadelphia since April, 2005.

The Phillies were outscored 21-7 in the sweep and are 2-7 against Atlanta this season.

“Our whole game has got to come together,” Phillies manager Charlie Manuel said. “We’ve been playing bad baseball.”

The sweep brightened the Braves’ outlook.

Manager Bobby Cox said the Braves still have “a long way to go, but we’re happy with our position.”

The only promising signs for the Phillies were another strong start for J.A. Happ, who gave up two runs in seven innings, and two hits by Jimmy Rollins, who ended his career-worst 0-for-28 drought.

“Our game is not together,” Manuel said. “I’ve been saying it for two or three weeks. ... We’re definitely losing games late.”

Philaelphia’s bullpen suffered losses in two of the three games in Atlanta.

With the score tied at 2, Brian McCann led off the eighth with a single off Ryan Madson (2-4). Pinch-runner Jair Jurrjens moved to second on Yunel Escobar’s sacrifice. Diaz followed with his run-scoring double to the center-field wall.

Pinch-hitter Garret Anderson added his first career pinch-hit homer, a two-run shot off Madson.
