TUCSON, Ariz. - Anthony Seratelli hit a tiebreaking homer to lead off the sixth inning, and four Omaha relievers combined to throw four no-hit innings as the Storm Chasers held on for a 4-3 win against Tucson on Friday.

Seratelli's homer, his 17th of the season, made a winner of Nate Adcock (7-4), who gave up 11 hits and three earned runs.

After Adcock left, Brandon Sisk, Tommy Hottovy, Juan Gutierrez and Donnie Joseph made the lead stand for Omaha. Tucson had runners on first and second with one out in the ninth, but Joseph induced a game-ending double play to get his first save.

Seratelli and Wil Myers each finished with two hits for the Chasers (70-50), who maintained their 15-game lead over Nashville in the PCL's American Conference North.

The teams continue their series at 9:05 p.m. Saturday.
