CHARLESTON, S.C. - The Citadel scored twice in the ninth and had runners on the corners before North Florida closer Corbin Olmstead was finally able to wrap up a 9-8 victory for the Ospreys on Wednesday night at Riley Park.

North Florida (32-13) completed a two-game season sweep but not before the Bulldogs scored twice in the ninth on an RBI single by Connor Walsh and an error. With runners at first and third and two outs, Olmstead secured his seventh save of the year with a strikeout of pinch hitter Austin Mapes.

Trailing 7-3 in the seventh, the Bulldogs (18-21) began their rally against Matthew Naylor on a pair of walks sandwiched around a single by Ryan Kilgallen. Mike Deese made it a two-run game when he dropped a double just inside the line in shallow right to chase Naylor in favor of Alex Smith.

Johnathan Stokes pulled The Citadel within one with a ground out, but the Ospreys tacked on single runs in the eighth on a safety squeeze executed by Ryan Roberson and the ninth on a solo homer by Olmstead.

Olmstead, who had not allowed an earned run in 27 1/3 innings entering the contest, hit Bret Hines with one out in the ninth but struck out Deese to bring North Florida within one out of victory. However, the Bulldogs would not go quietly, getting an infield single from Stokes followed by the Walsh base hit to right to make it 9-7.

Stephen Windham's ground ball to Kyle Brooks was misplayed for an error, allowing Stokes to score and moving the tying run to third before Olmstead closed it out.

Naylor went 4 2/3 innings in relief of starter Tyler Moore and earned his sixth win of the year without a loss, allowing three hits and three runs with four strikeouts. Austin Livingston started for The Citadel and was charged with the loss.

The Bulldogs jumped out to a 3-0 lead in the second on a two-run double by Bailey Rush and a sacrifice fly by Hines. The Ospreys bounced right back to plate six in the third including a two-run double by Donnie Dewees that extended the North Florida center fielder's hitting streak to 21.

Steven Hansen led the Bulldogs with a career-high three hits and scored two runs. Jason Smith struck out as a pinch hitter in the ninth to see his streak of reaching base via a hit, walk or hit by pitch snapped at 25 straight games.

The Citadel returns to Southern Conference action this weekend with a three-game series against VMI at Riley Park. The military rivals meet on Friday at 4 followed by contests on Saturday at 2 and Sunday at 1. All three games can be seen on the SoCon Digital Network.
