Oklahoma State will face Texas (29-25) in the final on Sunday.
Williams was involved in four of the Cowboys' five runs. He hit a leadoff double in the second inning and scored on a wild pitch by Oklahoma starting pitcher Corey Copping (4-1).
The Cowboys' cleanup hitter had an RBI double in the sixth to give Oklahoma State (37-17) a 3-0 lead. He pushed in another run with a triple in a two-run sixth for the second-seeded Cowboys.
