Perhaps Lisa Pitt just wanted to show UCLA what might have been.

The Arizona freshman pitcher, who was recruited by the Bruins, shut down the third-ranked Bruins' offense Saturday and led No. 1 UA to a 5-1 win and a season sweep of UCLA for just the second time, ever.

The Wildcats won the first game of the doubleheader at Easton Stadium in Los Angeles 5-3.

The win upped the Wildcats' record to 38-4 overall and a conference leading 11-1 record in Pacific 10 Conference play. Their lone loss is to Washington - the team they will face this Saturday in Seattle.

UCLA fell to 28-8 and is all but eliminated from the conference race with a 9-7 record.

For Pitt, the game was her 10th win of the year as she stayed unbeaten for the season.

Pitt got all the run support she needed in the fourth inning, when the Wildcats broke the game open with four runs.

In the first game of the doubleheader, the Wildcats were led by freshman shortstop Michelle Churnock and senior third baseman Krista Gomez, who each had two RBI for the game.

With a slim 4-3 lead in the top of the seventh inning, Brandi Shriver gave the Wildcats an insurance run with a first-pitch single to right field.

Aleah Poulsen singled to open the bottom of the seventh for UCLA, but Arizona senior pitcher Carrie Dolan (24-4) settled in and finished the game.
