Oklahoma second baseman Danny Black, rear, collides with right fielder Cody Reine (11) in the sixth inning of an NCAA College World Series game Sunday in Omaha, Neb. OU beat South Carolina, 4-3.

Omaha, Neb. ? Caleb Bushyhead homered and drove in the winning run, and Jeremy Erben and Ryan Duke worked out of bases-loaded situations in the eighth inning to lead Oklahoma to a 4-3 victory over South Carolina in the rain-plagued College World Series on Sunday night.

The start of the game was delayed 4 hours, 15 minutes, and play was halted for an additional 2:01 by rain and lightning in the middle of the sixth inning.

The Clemson-Arizona State game was postponed until this morning.

Bushyhead homered to break a 1-1 tie in the second, and he singled into the right-field corner to make it 3-2 in the fourth.

South Carolina was within a run after Duke walked Jackie Bradley with the bases loaded in the ninth, but Duke got Adrian Morales to fly out to end the game for his 12th save.

Oklahoma plays the Clemson-Arizona State winner Tuesday night, with South Carolina meeting the loser of that game Tuesday afternoon.
