CHESTNUT HILL, Mass. - All-America Alex White worked seven strong innings, but No. 4 North Carolina stranded 12 runners and committed three errors in a 3-1 loss to Boston College Thursday at Shea Field. The Eagles (31-21, 13-13 ACC) locked up a berth in next week's ACC Tournament with their first win over the Tar Heels (39-14, 17-10 ACC) in 10 meetings.

White (7-3) held the Eagles to just six hits and two earned runs over seven innings. He fanned six and issued only one walk before Jacob Stallings set down all three batters faced in the eighth in his second career outing.

Starter John Leonard worked 5 1/3 innings for the Eagles and allowed one run on five hits and three walks, while striking out five. Matt Brazis (1-0) picked up the win for Boston College, and Mike Belfiore struck out four over three innings to earn his eighth save.

Ben Bunting, Garrett Gore and Levi Michael had two hits each for the Tar Heels, while Barry Butera had a game-high three hits for the Eagles.

Neither team managed much in the way of offense over the first four innings, but the Tar Heels loaded the bases on a Ryan Graepel double and walks to Brett Thomas and Bunting with just one away in the fifth. However, Leonard buckled down to force fly outs by Michael and Dustin Ackley to preserve the scoreless tie.

The Eagles took a 1-0 lead in the bottom of the inning thanks to a pair of Tar Heel errors. Mike Sudol reached on a miscue by Michael to lead off the inning. He was sacrificed to second, took third on a fly ball to deep right and scored when Ackley misplayed a grounder off the bat of Andrew Lawrence for his first error of the season and the first run of the afternoon.

Carolina came right back to tie the score in the sixth on an RBI single by Cavasinni. Gore singled for the second time to end the day for Leonard, and reliever Nate Bayuk balked him to second before Cavasinni singled through the right side to knot things up at one apiece.

The Eagles went back in front on the bottom of the inning when Belfiore singled and scored on a Matt Hamlet sacrifice fly. Butera singled to move Belfiore to second, and a wild pitch put both runners in scoring position before Hamlet's fly ball to center gave BC a 2-1 lead.

The Tar Heels put runners on the corners with just one out in the seventh but were unable to push the tying run across. After Ackley singled to extend his hitting streak to seven games, Belfiore struck out Kyle Seager and BC shortstop Brad Zapenas robbed Gore of a potential game-tying base hit to end the threat.

Tony Sanchez extended the Eagle lead to 3-1 with a sac fly in the seventh. Robbie Anston started the rally with a single to left and moved around to third on a groundout and a wild pitch. Sanchez then lofted a fly ball to left and Anston beat the throw to the plate to give Boston College a run for the third straight inning.

The series continues at 1:30 p.m. Friday and 1 p.m. Saturday.
