QUEENS, N.Y. - St. John's Matt Wessinger hit a liner to left field that drove in the game-winning run as the University of South Florida baseball team (22-26, 13-8 BIG EAST) suffered a 6-5 walk-off loss to St. John's (32-14, 14-7 BIG EAST) Sunday afternoon at Jack Kaiser Stadium.

USF failed to deliver a knockout blow to the Red Storm by not holding leads of 2-0 and 5-2.

After working 1.2 innings of perfect relief, reliever Joe Cole gave way to closer Ray Delphey with two down and a 5-4 USF lead. St. John's tied the game after Jimmy Brennan was hit by a pitch and came across the plate on a double by Jimmy Parque.

With the game all square, the Bulls went down in order on strikes outs by Kevin Kilpatrick in the top of the ninth. Kilpatrick allowed just one hit in 3.2 scoreless innings to pick up the win in relief.

Delphey (1-3) stayed in to work the ninth.  A leadoff walk to Jermeny Baltz proved to be costly as pinch-runner Ferrara came around to score the game winning run.

Offensively, Jonathan Koscso led the way with three hits for the Bulls, who were out hit 10-9 on the afternoon. Ryan Lockwood finished up the three-game series with a two-hit outing. Lockwood went 5-for-11 at the plate with three extra base hits vs. the Red Storm this weekend.

After going down in order in the first inning, the Bulls strung together some offense in the second.

After a Todd Brazeal walk, a single from Junior Carlin and a wild pitch, the Bulls had runners on  second and third with nobody out.  Jonathan Koscso delivered by sending a shot back up the middle to score Brazeal. Carlin eventually scored two batters later on a sacrifice fly to give the Bulls a 2-0 lead.

St. John's responded by plating two in the third off Bulls starter Jimmy Moran, but USF answered quickly.

With runners on second and third and one out, Carlin scored on a wild pitch to make it 3-2 in favor of the Bulls in the fourth inning.

USF extended its lead the following inning, as Eric Sim came around to score on a throwing error by third baseman Greg Hopkins. With the bases loaded, Kosocso continued his big day as he sent a single off the Johnnies third baseman to plate Lockwood.

Lockwood's run was all the Bulls could muster as the Red Storm pushed across single runs in the bottom of the  fifth, sixth, eighth and ninth innings.

The Bulls will travel to Jacksonville, Fla., to take on North Florida in their final non-conference game of the season on Wednesday, May 12.

USF will then return home to take on first-place Connecticut next weekend in the final home series of the season and the final games at Red McEwen Field, the Bulls home since the 1960s.
