(SportsNetwork.com) - Aaron Harang hopes for better results than the last time he faced the Phillies.

The 36-year-old right-hander takes the mound for the Braves Sunday afternoon, as they attempt to complete a four-game sweep in Philadelphia.

The Braves, currently tied with Washington atop the NL East, haven't swept the Phillies in a four-game set since June 26-29, 1997. That was a home set for the Braves. Atlanta has never swept a four-game set in Philadelphia.

Harang surrendered nine runs -- eight earned -- on 13 hits over five innings of a 10-5 loss at Turner Field versus the Phillies on June 18. Harang has won two of his last three starts, and is coming off a victory Tuesday at Houston when he allowed six hits and a pair of runs in six innings. He's 4-3 with a 5.47 ERA in 14 games (13 starts) versus the Phillies.

David Buchanan, a winner of three straight starts, counters for the host team. The righty tossed five innings, allowing two runs on six hits and four walks, in a 7-4 home win over Miami Tuesday. He's never faced the Braves.

Atlanta won both ends of a double-header yesterday, 10-3 in the day game and 5-1 in the night contest. Tommy La Stella drove in five runs over the two contests, while Chris Johnson finished 5-for-9 with three RBI.

In the afternoon game, Justin Upton and La Stella each drove in three runs. Starter Ervin Santana (6-5), who entered the game with three straight losses, earned the win after giving up just two runs on seven hits and a walk with five strikeouts in 6 2/3 innings.

La Stella doubled twice and drove in two runs in the night game. Johnson added three hits and an RBI. Ryan Doumit homered and scored twice for the visitors.

David Hale (3-2) worked five innings for the win, scattering four hits and one run as Atlanta swept a double-header against the Phillies for the first time since Aug. 13, 1996 at Veterans Stadium.

Cameron Rupp posted a pair of hits and Jimmy Rollins knocked in the only run for the Phillies. In his Philadelphia debut, Sean O'Sullivan (0-1) exited after 5 2/3 frames, charged with eight hits and four runs while striking out three.

Atlanta has grabbed a 5-4 lead in this season's series with the Phillies.
