OMAHA, Neb. (AP) Michael Roth pitched 7 2-3 innings on three days’ rest, and South Carolina won its second straight national championship with a 5-2 victory Tuesday night that completed a two-game sweep over Florida in the College World Series finals. South Carolina (55-14) became the first team to ever go 10-0 in an NCAA tournament and the first since Oregon State in 2007 to go unbeaten in a CWS. The Gamecocks’ streaks of 16 NCAA tournament wins and 11 straight in the CWS are both the longest all-time. Peter Mooney doubled to start a three-run third inning and hit the Gamecocks’ first home run of the CWS in the sixth. After giving up four runs in the first inning of their opener against Texas A&M, the Gamecocks allowed just six in their other 50 innings here.
