CHAPEL HILL, N.C. — Garrett Boulware’s groundout scored Jay Baum in the 11th inning to lift Clemson to a 5-4 win over top-ranked North Carolina in front of 3,205 fans at Boshamer Stadium on Monday night.

The Tigers, who next host Gardner-Webb on Wednesday at 6:30 p.m., improved to 17-11 and 6-6 in the ACC, while the Tar Heels fell to 25-2 and 9-2.

Earlier in the day, Clemson lost a 6-2 game that had been suspended the night before by inclement weather.

In the second game, the Tar Heels jumped out to leads of 2-0 and 3-1 before Clemson clawed back with three runs in the sixth to take a 4-3 lead.

UNC tied the score in the seventh on a run-scoring groundout. Then both teams were unable to score a go-ahead run in the eighth, ninth, and 10th innings. Clemson loaded the bases with no outs in the 11th and plated the go-ahead run with one out on Boulware’s groundout.

Scott Firth (3-4) pitched 42/3 scoreless innings in relief to earn the win. He battled through adversity in three different innings as North Carolina stranded runners at second and third in the eighth, 10th, and 11th without scoring. Firth allowed three hits and two walks with one strikeout.

Chris O’Brien (0-1), the seventh of eight Tar Heel pitchers, suffered the loss, giving up two hits, one run, and one walk in one innings pitched.

In the first game, UNC righthanders Benton Moss and Trent Thornton combined to allow just six hits, two unearned runs, and one walk with 13 strikeouts to lead UNC over Clemson.

Thornton (6-0) pitched the final 61/3 innings to earn the win, giving up six hits, two unearned runs, and no walks with seven strikeouts.

Clemson starter Clate Schmidt (2-1) suffered the loss, as he yielded five hits, two runs, and one walk in two innings pitched. Zack Erwin pitched the final six innings and surrendered six hits, four runs (three earned) and two walks with one strikeout.
