BOULDER, Colo. (AP) -- Nate Tomlinson was fouled with one second remaining by E.J. Singler and sank the first free throw before deliberately missing the second to give Colorado a 72-71 win over Oregon Saturday night.

Oregon's Olu Ashaolu tied it at 71 with 7.6 seconds left and was fouled by Askia Booker, but he missed the free throw, and Andre Roberson corralled the rebound for Colorado.

Behind Booker's 17 points and 16 from Spencer Dinwiddie, the Buffaloes (16-7, 8-3) remained perfect at home in their first season in the Pac-12, improving to 7-0 in league play in Boulder. The last time they won eight of their first 11 league games was in 1997 in the Big 12.

Devoe Joseph led the Ducks (16-7, 7-4), who fell to 4-2 on the road in the Pac-12, with 18 points, Ashaolu scored 17 and Singler added 13 points and 12 rebounds.
