The game will pick up in the top of the sixth inning.
Clemson starter Scott Weismann worked out of a bases loaded jam in the second after designated hitter Ricky Eisenberg lined out to right.
Oklahoma put the game's first run on the board when shortstop Caleb Bushyhead dropped a single in shallow centerfield during the fourth, scoring rightfielder Cody Reine, who stole second after reaching on a swinging bunt single.
Clemson took a 4-1 lead in a bizarre bottom of the fourth.
Oklahoma starter Bobby Shore threw 14-straight balls to start inning to load the bases for John Hinson, who singled in Clemson's first run. Catcher's interference was called on the hit, but was declined by the Tigers.
Sooner head coach Sunny Galloway called right Jack Mayfield out of the bullpen to face Richie Shaffer, who knocked in another run with sacrifice fly to right. Mayfield then walked Boyd and gave up an two-run scoring single to Spencer Kieboom, giving the Tigers a 4-1 lead.
After Mayfield fell behind Chris Epps with a 2-0 count, Galloway called in lefty J.R. Robinson, who went on to strike out Epps.
The inning ended on a double-steal attempt with Kieboom at first and Wilson Boyd at third. Boyd was thrown out after the throw down to second was returned to home.
In the fifth, Kyle Parker hit his first career triple off the top of the centerfield wall. He scored when Brad Miller's routine fly ball was dropped by Oklahoma leftfielder Max White. With Miller at second, Hinson singled in Miller to give Clemson a 6-1 lead.
Through five innings, Weismann has given up three hits, struck out four and walked two.
