Red Sox take on Braves in Atlanta Wednesday.

ATLANTA (AP) — Brandon Phillips hit a two-out, two-run homer in the ninth inning Wednesday, highlighting his long-awaited season debut and capping the biggest comeback by the Boston Red Sox this year for a 9-8 win over the Atlanta Braves.

The Red Sox overcame a late six-run deficit and seesawed past Atlanta to sweep the three-game series between division leaders.

Boston, with the best record in the majors, scored six times in the eighth to make it 7-all.

After Freddie Freeman hit a solo homer with two outs in the Braves eighth, the Red Sox bounced back for their 97th win this year.

The 37-year-old Phillips was called up from Triple-A Pawtucket on Tuesday and given his first start at second base in the final game of the interleague set.

After Andrew Bentinendi's one-out single off A.J. Minter (4-3), Phillips hit the two-out homer deep into the left field seats.

Braves left fielder Ronald Acuna Jr., who hit another leadoff homer in the first, didn't move as Phillips' shot sailed over his head.

Phillips scored three runs, drew two walks and made the most of his first hit with Boston.

Braves stadium organist Matthew Kaminski played "Welcome Back" before Phillips' first at-bat in the second inning. Phillips, a high school star in the Atlanta area who played most of last season with the Braves, tipped his helmet and then walked.
