LAS VEGAS - The Storm Chasers' celebration will have to wait at least one more day.
Former Omaha pitcher Sean O'Sullivan allowed four hits and one run over seven innings Friday, helping Las Vegas to a 5-1 win and denying the Storm Chasers a chance to clinch the PCL's American Conference North.
Nashville's 7-2 win over Tacoma earlier Friday had already assured that Omaha wouldn't clinch the division. The Chasers and Sounds open a four-game series at 7:05 p.m. Saturday, and Omaha would clinch the division with one win.
The Chasers' only run against Las Vegas came on Mitch Maier's leadoff home run in the fourth inning. Anthony Seratelli followed with a double, but Wil Myers struck out and Seratelli was caught trying to steal third. Clint Robinson struck out to end the inning.
The Chasers had another chance in the seventh inning after loading the bases with no outs. But O'Sullivan (14-5) struck out David Lough, Adam Moore and Kurt Mertins to escape the jam.
