Troy Tulowitzki led off the eighth with a double before scoring on Holliday's second homer of the season.
Braves third baseman Chipper Jones laced an RBI double just three batters into the game. Tom Glavine made the lead stand up, scattering three hits in six and a-third innings. But Blaine Boyer served up Holliday's blast, which snapped the Rockies' five-game losing skid.
Winning pitcher Matt Herges worked a hitless eighth after Aaron Cook limited the Braves to two hits in seven innings.
Manny Corpas got the final three outs for his second save.
The game lasted just 2:05, the shortest nine-inning contest in Coors Field history.
