ALSO MONDAY

FRESNO STATE 12, ARIZONA STATE 9: Steve Susdorf's two-run homer capped Fresno State's six-run seventh inning as the Bulldogs stunned Arizona State on Monday night to advance to the College World Series for the first time since 1991.

Fresno State (42-29) became the first No. 4 seed to reach Omaha since the NCAA expanded the tournament field to 64 teams in 1999. The Bulldogs will open against Rice (47-13) on Sunday.

The Sun Devils (49-13), the No. 3 national seed, had been unbeaten in four postseason games before consecutive losses to the Bulldogs.

Matt Newman's second homer of the game gave Arizona State a 5-4 lead in the fifth, but Susdorf tied it in the top of the sixth with an RBI single.

Fresno State loaded the bases with two outs against reliever Mike Leake (11-3) in the seventh. Leake hit Gavin Hedstrom with a pitch to give the Bulldogs a 6-5 lead, and Erik Wetzel followed with a bases-clearing double to make it 9-5. Susdorf then homered over the right-field fence, and Tommy Mendonca added an RBI single in the ninth.

Arizona State scored four runs in the bottom of the ninth, but the rally fell short. The Sun Devils stranded 15 baserunners after leaving 12 on base in their loss Sunday.

Kris Tomlinson (2-1), the third of five Fresno State pitchers, threw a hitless sixth for the win.

The lead was short-lived as Danny Grubb had an RBI single, and Hedstrom drove a pitch from reliever Stephen Sauer deep to left for a 7-5 lead in the bottom of the fourth.
