Colorado Springs' Tyler Matzek (5-2) took care of business with 7 2/3 innings of four-hit ball and hit his first homer of the season in a 2-0 victory at Nashville.
Matzek homered in the sixth and the Sky Sox added an insurance run in the ninth Tuesday.
The Sky Sox only had four hits but Matzek only walked two and struck out three before Chris Martin finished up for his fourth save.
Ryan Wheeler had two of Colorado Springs' four hits. Kyle Parker scored the other run and Jackson Williams drove him in.
