OMAHA, NEB., JUNE 4 -- Adam Smith's two-run single started a six-run sixth inning and Pat Hope allowed seven hits tonight as Oklahoma State beat Stanford, 6-2, to remain unbeaten in the NCAA College World Series.

Oklahoma State's Robin Ventura had his 58-game hitting streak ended. The all-America was hitless in five at-bats.

The victory in the winners' bracket final gave third-ranked Oklahoma State (59-11) an automatic berth in the title game either Saturday or Sunday.

Stanford (50-17), ranked second, will meet No. 7 Louisiana State (49-18) in an elimination game Friday afternoon, followed by Oklahoma State against No. 1 Texas (60-10).

A Texas win in Friday's nightcap would force a Sunday championship game, with the winner of Friday's games meeting Saturday for the right to play Oklahoma State Sunday. If Oklahoma State beats Texas Friday, it would play in the title game Saturday.

With Stanford ahead by 2-0, Jim Ifland and Jimmy Barragan started the one-out rally in Oklahoma State's sixth inning with singles off all-America Jack McDowell (12-5). Monty Fariss walked to load the bases for Smith, who singled to center for two runs.

Benny Castillo then singled in the go-ahead run and Smith scored on a wild pitch. Brad Beanblossom tripled in Castillo and scored the sixth run of the inning on Anthony Blackmon's sacrifice fly.

Hope (13-2) pitched his second complete game of the tournament. He had a season-high 11 strikeouts and walked none.
