Seniors Katiyana Mauga and Danielle O'Toole led the Wildcats to a 5-0 win over South Carolina, advancing to the winners bracket of the Tucson Regional.
Mauga's third inning home run was the 91st of her career, breaking the record by a Pac-12 player. She is four home runs shy of the NCAA record.
"When Kati's hot and she's htting the ball where she's pitched, she's a weapon," said head coach Mike Candrea. "And obviously any swing she takes the ball can leave the ballpark. The thing I like right now, is we're scoring a ton of runs with not just the home run. If you look at the bottom of the order, they've been very productive, and to me I think that's huge."
Pitcher Danielle O'Toole took a no-hitter into the seventh inning until it was broken up by a one-out double from Victoria Williams. She finished with a one-hit shutout to improve her record to 29-4 on the season.
