South Bend (17-13) added another couple of runs in its second at bat and then stretched the advantage with eight runs in the fourth inning and another in the eighth inning.
The TinCaps (12-17) scored their only runs in the bottom of the third, as Mallex Smith brought home Ronnie Richardson with an RBI-single. Dustin Peterson followed that by driving in Smith on a sacrifice fly after Smith stole both second and third base.
Fort Wayne threw a half-dozen pitchers, including Richardson, who despite being an outfielder worked a scoreless ninth inning.
The Silver Hawks banged out 16 hits in the victory.
TinCap starter Bryan Verbitsky (0-1) allowed seven runs (six earned) in two innings pitched.
South Bend third baseman Joe Munoz doubled in each of his first four at-bats, which tied a Midwest League record for an individual player. As a team, the Silver Hawks had nine doubles, which was just one shy of a league record.
