WILLIAMSBURG, Virginia - Michael Bass singled in Jake Koenig with the go-ahead run with two out in the top of the ninth as UNCW clinched the regular season Colonial Athletic Association title with a 5-4 win over William & Mary on Friday at Plumeri Park.

The Seahawks won their first regular season title since 2008 with the win as their record improved to 31-19 overall and 21-5 in the league. The Tribe, meanwhile, dropped their fourth straight outing, all in conference play, and dropped to 28-22 and 11-15 in the CAA.

With two outs in the ninth, Koenig doubled to left center and would score two batters later as Bass ripped a single into center off losing pitcher John Farrell (2-2). Farrell had pitched well in relief, allowing just that one run on two hits and six strikeouts in four innings of relief.

Kelly Secrest (3-2) topped Farrell with three innings of two-hit shutout relief.

Koenig finished with two hits on the evening as the Seahawks held a 9-5 advantage in the hit column. Hunter Ridge also added two hits while Tyler Molinaro belted his league-leading 13 homer of the season to give UNCW a 1-0 lead in the top of the first.

Trailing 2-1 in the fifth, W&M's Michael Katz slammed a three-run homer off UNCW starter Mat Batts to give the Tribe a 4-2 lead. All three runs were unearned following a Seahawk error.

That lead would be short lived as UNCW drew even with a pair of runs off W&M starter Cole Shain in the top of the sixth.

Katz was the only hitter in the lineup with two hits for the Tribe.

Batts pitched in and out of trouble for most of the night, going six innings and allowing four runs, just one earned. He walked two and struck out five.

Shain last five innings, surrendering four runs, two earned, on seven hits and two walks.

Drew Farber knocked in two runs for the Seahawks, who improved to 6-4 in one-run games.

The series concludes on Saturday with a 2 p.m. start at Plumeri Park.
