South Carolina (44-17) needs to defeat the Sooners (42-24) once more to reach its third consecutive College World Series.
LB Dantzler's RBI double keyed a three-run second that was all Roth (7-1) needed. The senior worked 7 2-3 innings, giving up six hits. Roth ran off the mound in the eighth to a loud, standing ovation from the sellout crowd of 8,242 at Carolina Stadium.
After shaking hands with coach Ray Tanner, Roth came out of the dugout to acknowledge the cheers with a wave of his cap.
The Gamecocks will face the Sooners in game two Sunday night at 7 PM.
