FORT WORTH, Texas -- Jason Coats hit a game-winning RBI single to give TCU a 5-4 win over Oregon State on Sunday night and clinch a berth in the super regionals.

Facing a full count with one out in the bottom of the ninth, Coats slapped an opposite-field single to right field to score Bryan Holaday from second.

"It's the best feeling ever," Coats said. "I saw everybody charging at me and I was like, gosh, what just happened?"

Oregon State (37-19) took a 4-0 lead in the third after Stefen Romero drove in three runs on a double with the bases loaded.

TCU (39-18) answered with a run in the third, then tied it at 4-4 with three runs in fifth. Oregon State had runners at first and second in the eighth, but Jared Norris grounded into an inning-ending double play.

Reliever Eric Marshall (2-2) got the win with one shutout inning, while Kevin Rhoderick (3-3) took the loss.

"This is obviously a historic night for our program," TCU coach Jim Schlossnagle said. "I couldn't be more proud of our team."

The Horned Frogs advance to the super regional for the first time.

Oregon State was playing its second game of the day in 90-degree heat after beating Texas A&M, 13-5, in an elimination game earlier Sunday.
