Cedric Hunter doubled, tripled and homered, driving in five runs as Mississippi routed Chattanooga 14-1 on Sunday.
The Braves led 1-0 going into the fourth inning, when Hunter's bases-clearing triple highlighted a seven-run outburst.
Mitch Atkins pitched six hitless innings for Mississippi, and the Lookouts (25-39) didn't collect their first hit until Daniel Mayora's one-out single to right off Jorge Reyes in the seventh.
Game five of a five-game series in Mississippi is tonight at 8 EDT.
Raydel Sanchez (0-4, 9.13) is scheduled to start for the Lookouts, with Aaron Northcraft (7-2, 2.88) scheduled for the Braves.
