NC State 8, North Carolina 1 • North Carolina State's Carlos Rodon pitched eight shutout innings to continue his mastery of North Carolina, and the Wolfpack knocked out ACC pitcher of the year Kent Emanuel early in an 8-1 victory at the College World Series on Sunday.
Rodon held the No. 1 national seed Tar Heels hitless into the fifth inning. He allowed five hits and struck out eight.
It was the sophomore left-hander's second straight dominating performance against the Tar Heels. The result was more satisfying this time. Three weeks ago he allowed one hit and struck out 14 in 10 innings but got no decision in a 2-1, 18-inning loss in the Atlantic Coast Conference tournament.
