TUCSON, Ariz. -- Fourth-ranked Arizona hit four more home runs, including two by Katiyana Mauga, and run-ruled Stanford for the third consecutive game at Hillenbrand Stadium. The Wildcats defeated Stanford 9-1 in five innings to improve to 40-1 on the year.
The sweep was Arizona's fourth conference sweep in as many tries. Arizona had not swept four conference series in any season since the Pac-12 went to three-game series in 2011. The Wildcats are 12-0 in league play for the first time since 1994.
Arizona's four homers brought its weekend total to 15 and brought its season total to an NCAA-most 71. Sixteen of those belong to Mauga, who took over the Pac-12-lead on Sunday and moved into a tie for seventh in NCAA history with 83 career homers. Mauga, the reigning Pac-12 Player of the Week, hit four homers in nine at-bats vs. Stanford.
Mo Mercado and Jessie Harper also homered in the game. The duo hit back-to-back home runs in the bottom of the fifth to end the game via the run-rule. Both Mercado and Harper hit three home runs in the series.
Danielle O'Toole and Taylor McQuillin teamed up for the two-hitter in the circle. O'Toole retired the first nine batters she faced before allowing a run on two hits in the fourth inning. McQuillin put a zero on the scoreboard in the fifth. O'Toole (21-1) picked up the victory, striking out six batters without a walk in the four innings.
Arizona outscored Stanford 41-2 in the three mercy victories and the Wildcats hit more home runs in the three games (15) than their pitchers allowed total hits (10).
Arizona wasted little time in the bottom of the first grabbing another lead, and it did it on yet another home run. Katiyana Mauga hit her third homer of the weekend, Arizona's 12th, a three-run bomb to put the Cats up 3-0 in the early going.
Mauga was at it again in the third, hitting her second homer of the game and fourth of the weekend, a two-run shot to put the Cats up 5-0.
The teams traded runs in the fourth.
