GREENVILLE, S.C. -- South Carolina coach Frank Martin wasn't going to feel bad about this victory, no matter how close the Gamecocks came to blowing a 20-point lead over rival Clemson.
Michael Carrera scored 14 points and freshman PJ Dozier had 13 as South Carolina gave up most of its large lead before holding on to defeat rival Clemson 65-59 and open 10-0 for the first time in 82 years.
"When you go on the road and win, you do cartwheels on the highway all the way home," said Martin, South Carolina's fourth year coach who's got his team off to its best start since 1933-34.
That group, led by coach A.W. Norman, won its first 17 games before losing. Martin's not worried about any of that, just about prepping for the next one.
"We've got to stay in the moment," Martin said.
It was an almost a moment to forget for the Gamecocks, who led 38-18 in the first half before seeing the margin shrink to 57-53 with six minutes left. Still, South Carolina held on with defense and timely foul shooting to remain undefeated.
"It feels good, not just that we beat Clemson, but that we continued our winning streak," South Carolina guard Sindarius Thornwell said.
Clemson (7-4) rallied back in the second period to cut the lead to 57-53 on Donte Grantham's put-back basket with 6:10 to go. The Tigers made only one of their next six baskets in falling to the Gamecocks for a second straight season.
