Trailing 3-0, USF got on the board when Jimmy Falla walked with the bases loaded to cut into the Seton Hall lead.
The Bulls exploded for five runs in the seventh, delivering the knockout blow to Seton Hall starter Joe Dirroco, who entered the game with a 1.54 earned run average.
The Bulls put the first three men on to load the bases and tied the game as Jonathan Koscso singled through the right side to score Andrew Longley. The Bulls took the lead with an RBI ground out by Junior Carlin to even the game.
Sam Mende extended the Bulls' lead with an RBI-triple to left center to drive in Koscso. Alex Mendez capped the Bulls scoring in the inning with a two-out RBI single through the left side.
The Bulls would get Bulls starter Kyle Eastham off the hook for the loss.
Eastham gave the Bulls a quality effort, making only one mistake on the afternoon however it would be the difference in him picking up win instead of a no-decision. Seton Hall would do all their damage against Eastham with one-swing of the bat as Ryan Sullivan sent a drive over the right field fence to for a three-run homer.
Following the homer, Eastham settled and kept the Pirates advantage at 3-0. He would go 5.2 allowing just three hits, walking three with four strikeouts. Two of Eastham's three runs allowed were earned.
With two outs in the sixth, Eastham would put two runners on and reliever Trey Dahl walked the only batter he faced but Jimmy Moran would come in and escape the jam for the Bulls.
Moran would pick up the pitching with 1.0 inning of relief to move to 3-0 on the season.
Senior closer Kevin Quackenbush entered the game with no-outs in the 8th and the bases loaded. He would rely on his defense as Mende and second baseman Luis Llerena combined for some fancy glove work to turn a big double-play despite giving up a run on the play.
Quackenbush would work a scoreless ninth to record his eighth save in nine chances and second in as many nights.
With the win, the Bulls move their record to .500 at 17-17 for the first time since following the Florida A&M series which concluded March 5.
Koscso kept his hot hand at the plate going with his five straight multi-hit game tallying two of the Bulls nine hits on the day scoring two runs.
The Bulls will look for their first series sweep of the season Sunday at Noon in the finale with LHP Matt Reed on the mound for the Bulls.
