The Wildcats scored five runs before Lehigh could record an out and they rolled to a five-inning mercy rule win.
Arizona got started in the first. Lead-off hitter Caitlin Lowe started with a single Autumn Champion and Kristie Fox walked, before Jackie Coburn lined a two-run single to score Lowe and Champion. Shelly Schultz finished the first inning scoring with a three-run homer.
Coburn drove in two more runs when Adrienne Acton and Lowe scored on her second inning single.
A bases loaded walk in the third gave Coburn her fifth RBI. Calista Balko and Lowe each hit a two-run home run in the bottom of the fourth to cap the scoring.
Alicia Hollowell, Leslie Wolfe and Taryn Mowatt teamed for a no-hitter. Hollowell and Wolfe pitched two inning each, while Mowatt closed out the game in the fifth. The three combined for 10 strikeouts, five from Hollowell.
Arizona will meet Oklahoma State at 1:30 p.m. (MST/PDT) Saturday in the winner's bracket
