CHAPEL HILL, N.C. -- No. 13 North Carolina capped off a three-game series sweep of top-ranked Virginia (44-12, 22-8 ACC) as the Tar Heels (44-12, 20-10 ACC) used a three-run fifth inning en route to a 3-2 win against the Cavaliers Saturday afternoon on senior day at Boshamer Stadium.

Carolina tallied its first sweep of Virginia since 2005 and held the ninth-highest scoring team in the country to just three runs during the weekend series. The Tar Heels delivered a loss to Virginia starter Will Roberts for the first time in his career, as Roberts came into Saturday with a flawless 17-0 mark.

The Tar Heels tallied four hits, including a pair of doubles, in the three-run fifth as Seth Baldwin and Colin Moran came up with the run-producing knocks.

Brian Holberton started things off with a one-out double in the right center field gap and after moving to third on a wild pitch scored when Baldwin rocketed a ball past the second baseman as the infield was drawn in.

A single by Chaz Frank put runners on the corners and Frank moved to second with his ninth steal of the year putting two runners in scoring position for Moran. The Cavaliers went to the bullpen and brought in left-hander Kyle Crockett to face Moran.

The freshman was facing a 2-2 count when he went with a pitch and sliced it down the left field line, just inside the line and into the corner for a two-run double giving the Tar Heels a 3-1 lead.

After allowing one run over his first five innings of work, Chris Munnelly came out with a lead in the sixth and picked up a foul out and a ground out for two quick outs in the frame. A hit by pitch put Kenny Swab on base and a pitch in the dirt allowed Swab the opportunity to move up but Jacob Stallings pounced on the ball and fired to second to get Swab and pick up his 27th caught stealing of the year.

A lead off walk to open the seventh would end Munnelly's day as Greg Holt would be summoned from the bullpen.

Holt would allow a walk and a bunt single to Keith Werman to load the bases for the top of the order. Holt was able to get a punch out of John Barr and a ground out by Chris Taylor but the Wahoos were able to push across a run on the second out of the inning, cutting Carolina's lead to 3-2.

John Hicks turned on the next Holt offering and ripped it down the third base line but Colin Moran was there to corral it and fire to first for the third and final out of the seventh.

The Tar Heels used their traditional mix-and-match pattern in the eighth as Holt picked up a fly ball to center field before left-hander Tate Parrish did the same for out number two.

Freshman Shane Taylor came on and struck out Swab for the final out of the eighth keeping Carolina in front.

Carolina had a chance to add to its lead in the bottom half of the eighth when Tommy Coyle doubled off the right field wall and moved to third on a sacrifice bunt off the bat of Stallings.

With Ben Bunting at the plate Carolina attempted a safety squeeze but the Justin Thompson offering was in the dirt and the Cavaliers were able cut down the charging Coyle to stop the rally.

Closer Michael Morin was called upon for the ninth inning looking for his eighth save of the year and second of the weekend.

Morin allowed a single to right field to open the inning before buckling down and getting a fly out to right field for the first out and then struck out pinch hitter Shane Halley.

Pinch runner Mitchell Shifflet would steal second to put the tying run in scoring position but Morin struck out his second consecutive batter to end the game and cap off the series sweep.

Colin Moran equaled a season high with a perfect 4-for-4 performance at the plate and added to his league-leading total of 67 RBI.

Seth Baldwin brought production from the nine-hole for the Tar Heels as he was 2-for-3 with a run scored and a run driven in.

Morin becomes the first closer since Andrew Carignan in 2007 to register at least eight saves as Carignan closed out 18 games for the Tar Heels in the College World Series season.

Next up for the Tar Heels is a trip to Durham for the 2011 Atlantic Coast Conference tournament set to run May 25-29 at the Durham Bulls Athletic Park.

Carolina will be the No. 4 seed in the tournament and will be paired with No. 1 Virginia, No. 5 Miami and No. 8 Wake Forest in a pool-play format. Game times and dates will be announced at 3 p.m. on Sunday.
