EUGENE, Ore. -- Geri Ann Glasco hit three of a school-record eight home runs Sunday as No. 2 Oregon won a rubber match with No. 19 Washington 15-6 at Howe Field.

The Ducks (30-4, 8-1 Pac-12) led 3-0 on home runs by Jenna Lilley and Glasco before exploding for 10 runs in the third inning. Oregon clubbed five homers in the inning -- two-run shots by Hailey Decker and Glasco, a solo shot by Janelle Lindvall as she went back-to-back with Glasco, another two-run blast by Nikki Udria and finally a three-run homer by Decker.

Washington (31-9, 3-5) joined in on the power surge with two solo shots off UO starter Cheridan Hawkins in the top of the fourth, but the Ducks got both runs back in the bottom of the inning on Glasco's third homer and an RBI double by Danica Mercado. The Huskies rallied for four runs in the fifth off Hawkins and reliever Karissa Hovinga, before Hawkins struck out the final hitter after being reinserted.

The previous record for home runs in a single game was six back in 2013. The only other players in school history to hit three homers in a game are Kathy Stahl against Oregon State in 1995 and Missy Coe against Wichita State in 2000.
