Clemson took advantage of Oklahoma's fourth-inning pitching meltdown and a costly error in the fifth to beat the Sooners 6-4 at the College World Series on Wednesday.
Oklahoma scored each of the last three innings but couldn't come all the way back from the 6-1 deficit it faced when the game was suspended after the fifth inning Tuesday because of weather.
The Tigers (45-23) move to the Bracket 2 championship game on Friday against either Oklahoma (50-17) or South Carolina. Those teams play Thursday, and the winner would have to beat Clemson twice to make it to next week's best-of-three finals.
Clemson starter Scott Weismann (9-2) allowed a run and three hits over five innings before the weather halted play Tuesday night. The Sooners' Bobby Shore (10-5) took the loss.
