A day after edging No. 6 Oregon in a pitcher's duel, 2-0, third-ranked Arizona plated 10 runs on 12 hits and fought off a late Oregon surge to win 10-7 and clinch the series over the Ducks.
Katiyana Mauga broke the Arizona record with her 88th career home run, her second of the series and fifth in UA's last four games.
Oregon scored all seven of its runs on three home runs, two from Gwen Svekis, who brought in five runs with two swings of the bat. Danica Mercado added a two-run homer in the sixth.
Arizona, the nation's leader in home runs, plated just one of its 10 runs via the long ball, but a special long ball at that.
Leading off the bottom of the fourth, Mauga drilled her 88th career home run, an opposite-field shot that meant much more than the 7-5 lead it gave the Wildcats at the time. Mauga passed Stacie Chambers for first place in Arizona history in career homers and moved alone into third place in NCAA history.
Mauga is now two back of the Pac-12 record and seven shy of the NCAA mark. No. 88 was No. 21 on the year for Mauga, who is second in the country in 2017.
The homer was one of three hits on the day for the senior, who is now 22-for-her-last-43 (.512) with 11 home runs over Arizona's last 14 games. The three hits marked a season-high for Mauga, who picked up her eighth career three-hit outing.
Reyna Carranco also notched three hits for UA as her late-season surge continues. Carranco went 3-for-4 with an RBI and two runs scored and now leads the conference hitting .455 in league play.
Taylor McQuillin earned the victory for Arizona. McQuillin allowed six runs on seven hits with five strikeouts and three walks. She improved to 15-1 on the season. O'Toole got the final five outs of the game to earn her first save of 2017.
Arizona will go for the series sweep over the sixth-ranked Ducks on Saturday at 2 p.m. MST. The game will be televised on ESPN2.
