Arizona State had outscored Utah 11-2 through the first six innings, before the Utes put up six in the seventh and eighth combined.
Up 13-8 in the ninth inning, senior right-hander Ryan Hingst loaded bases when ASU manager Tracy Smith pulled him to insert junior righty Sam Romero.
Romero threw 46 pitches in a 2 2⁄3 innings start Saturday. It look him one pitch to get a 4-5-6 double play Sunday, ending the game with a 13-8 win.
It was without perfection, but the Sun Devils (17-22, 9-9 Pac-12) handled business, sweeping the Utah Utes (9-28, 4-11) on Sunday afternoon at Phoenix Municipal Stadium.
