The Ducks’ five homers were their most in a game since clubbing a school record six against Michigan in 2013.

SALT LAKE CITY -- Oregon hitters smashed five home runs and the Ducks defeated Utah 15-9 on Sunday in the second of a three-game series against the Utes.

The second-ranked Ducks improved to 25-3 (5-0 Pac-12) with the victory while the Utes slipped to 20-11 (0-5).

Oregon has beaten Utah 15 consecutive times and the Ducks will go the sweep on Monday.

Utah jumped out to the early lead when Kate Dickman hit a solo homer in the first inning off Oregon starting pitcher Geri Ann Glasco.

The Ducks tied it up in the second when Hailey Decker scored from third on a RBI groundout. Oregon took a 3-1 lead in the third when, after a pair of two-out walks, Janelle Lindvall ripped a triple off the wall in left to drive in a pair.

Koral Costa added to the lead when she hit her team-leading eighth homer of the season, a two-run bomb to center field, in the fourth inning.

The Ducks had a 5-1 lead entering the fifth when they exploded for five more runs. Jenna Lilley scored the first run of the inning after an error by the first baseman on a grounder. Decker followed with a three-run blast to left field to make it a 9-1 game before Danica Mercado crushed a line drive solo shot to right for a 10-1 advantage.

Just three outs from a run-rule, Utah would not go down without swinging. The Utes tallied six runs in the bottom of the fifth, including a three-run blast by Dickman, her second homer of the game.

Oregon responded and made it an 11-7 lead in the top of the sixth as Jenna Lilley hit a solo homer to right, the Ducks’ fourth home run of the game. Lilley homered again in the Ducks’ four-run seventh inning, the freshman’s first career multi-homer game.

With 15 more on Sunday, the Ducks have scored 61 runs through its first five Pac-12 games. Lilley went 3-for-3 with four runs and three RBIs to pace the Ducks. Oregon’s 3-4-5 hitters combined to go 7-for-12 against the Utes.
