The Storm Chasers got two-run homers from Xavier Nady and Quintin Berry to double up the Sounds 4-2 Thursday night in Nashville.
Jarrod Dyson started the game with a double and went to third on a throwing error by left fielder Khris Davis. Tyler Thornburg (0-8) retired the next two batters before giving up a home run to Nady, his 11th of the season, to give Omaha a 2-0 lead.
The Sounds answered with a run in the bottom of the first on a Josh Prince double, a wild pitch by Chris Dwyer (5-4) and a Sean Halton single.
The lead remained at 2-1 until the eighth when Willy Taveras singled and later scored on Berry's first home run of the year.
Prince again doubled in the ninth to drive in Stephen Parker to make it 4-2.
