Luis Domoromo generated the only offense that Fort Wayne would need, as he cranked out an opposite-field double to score Corey Adamson.
Ross (4-4) allowed just three hits and two walks on 86 pitches, as he blanked Beloit (16-7 second half, 59-34) for his first victory since April 25.
The right-hander was backed by Gott, who yielded just one hit in two innings - his longest appearance as a professional since he was selected in the sixth round out of the University of Kentucky in June.
Nunn pitched a perfect ninth with two strikeouts to earn his sixth save this season.
Fort Wayne (8-15, 51-41) scored its run with one out in the fifth against right-hander Dylan Covey (0-1).
Corey Adamson drew a walk and then came around on Domoromo’s 13th RBI and second double of the season. Otherwise, Covey, who was pitching in his first Midwest League game after Oakland selected him in the fourth round this year, contained the TinCaps to three hits and two walks.
Beloit reliever Derek DeYoung twirled three scoreless frames.
The Snappers best opportunity to score was in the second inning when Ross walked Matt Olson and John Wooten doubled with one out. But with runners at second and third base, Ross managed to induce a groundout back to the mound against Sam Roberts and struck out Nick Rickles to end the threat.
The victory was Fort Wayne’s seventh shutout win of the season and first in 14 games.
