Yankees 6, Braves 4: Alex Rodriguez hit his 23rd career grand slam, matching Hall of Famer Lou Gehrig's record as the New York Yankees scored six runs in the eighth inning to rally past host Atlanta.
Nick Swisher hit a tiebreaking two-run homer off Cory Gearrin two batters after Rodriguez connected against Jonny Venters.
CC Sabathia (8-3) left trailing 4-0 after seven innings but was the beneficiary of the rally. The big lefty gave up four runs on a season-high 10 hits with two walks and six strikeouts.
The Yankees matched their season high with their fifth straight win. They have won 10 of 12.
