EUGENE, Ore. (AP) Elgin Cook scored 18 points to lead No. 17 Oregon to a 100-82 victory over San Francisco on Sunday.
Jason Calliste had 16 points for the Ducks (4-0), who had six players score in double figures. Mike Moser added 13 points and seven rebounds.
Kruize Pinkins led the Dons (3-3) with 20 points and 11 rebounds.
San Francisco challenged Oregon on a couple different occasions in the second half, but the Ducks responded each time.
The Dons closed to 61-55 on a free throw by Tim Derksen with 10:54 left, but Oregon hit 3-pointers on consecutive possessions to push the lead back to 12.
The Ducks led by as many as 19 in the second half and shot 32 for 60 from the field.
Oregon's first three baskets were 3-pointers, but the Dons - despite missing 10 straight shots - took the lead on a layup from Cole Dickerson with 14 minutes left in the first half.
The teams traded baskets before Oregon started to take control. Moser sparked a 10-3 run after taking a charge with 5:56 to go in the half. He scored on the other end on a 5-foot floater, and then Damyean Dotson slashed to the hoop to give Oregon a 32-24 lead.
