FORT WORTH, Texas -- Freshman Tyler Alexander threw a six-hitter and TCU advanced to its fourth NCAA Super Regional in six years, beating Sam Houston State 6-1 on Sunday night.

TCU (45-15), the No. 7 national seed, needed only nine innings against Sam Houston this time. The Horned Frogs will host a super regional for the first time.

The Bearkats (43-19) beat Siena 9-2 earlier Sunday. That game started only about 12 hours after their 3-2 loss to TCU in 22 innings until about 2:30 a.m. CT Sunday.

Alexander (10-3) also had a complete game in the Big 12 tournament. Alexander, a lefty, has given up only six runs his past seven starts.

Garrett Crain's RBI single in the third broke a 1-all tie. Boomer White, who had the game-winning hits in TCU's first two Regional wins, added an RBI single.

Bearkats starter Andrew Godail (3-1) allowed two runs and five hits in three innings.
