EUGENE, Ore. (Interstat) — The Oregon Ducks used a dominant first half and a 21-point performance from Mia Jacobs to cruise past the Portland Pilots 85-59 in a nonconference women’s basketball game Thursday afternoon at Matthew Knight Arena.

A crowd of 6,279 saw the Ducks improve to 12-1 on the season, while Portland fell to 5-6.

Oregon established control early, holding Portland to just seven points in the opening quarter while building a 19-7 lead. The Ducks’ defensive pressure was the catalyst, forcing eight Portland turnovers in the first period and converting them into easy scoring opportunities. The Pilots struggled to find any offensive rhythm, shooting just 3-of-14 from the floor in the quarter.

The second quarter offered more of the same, as Oregon extended its lead. A 10-2 run midway through the period, capped by a Katie Fiso-assisted three-pointer from Avary Cain, pushed the advantage to 31-13. The Ducks led 44-19 at halftime, having forced 14 Portland turnovers and scored 23 points off those miscues. The Pilots managed only 12 points in the second quarter.

Portland showed signs of life after the break, erupting for 24 points in the third quarter. Lainey Spear, who led the Pilots with 15 points, was active in the paint, and Dyani Ananiev hit a pair of three-pointers during the period. However, Oregon’s offense, led by Jacobs, never cooled off. The sophomore from Perth, Australia, scored 13 of her game-high 21 points in the third quarter, including three three-pointers, to keep the Pilots at a distance. The Ducks led 72-43 heading into the final period.

The most important part of the game was Oregon’s overwhelming first-half performance, which rendered the final 20 minutes academic. Their defensive intensity from the opening tip created a steep hill for Portland to climb. The Ducks scored 23 points off 21 Portland turnovers for the game, while the Pilots managed only seven points off Oregon’s 14 giveaways.

Fiso orchestrated the Oregon offense with precision, finishing with a double-double of 10 points and 11 assists. Amina Muhammad added 12 points and Avary Cain scored 11 for the Ducks, who shot 50% from the field.

For Portland, Spear’s 15 points, three assists and a block paced the effort. Rhyan Mogel distributed eight assists, and Florence Dallow came off the bench to contribute nine points. The Pilots did hold a 34-26 advantage in points in the paint but were undone by their ball security and Oregon’s efficient transition game.

Oregon next travels to face Stanford on Sunday in San Francisco. Portland will visit crosstown rival Portland State on Sunday.
