CORVALLIS, Ore. (AP) Oregon State Coach Wayne Tinkle said his team ''drew a line in the sand'' during a timeout with about three minutes left against UCLA, with the Beavers having blown nearly all of a 17-point lead.

Malcolm Duvivier added 19 points for the Beavers, (13-5, 4-2 Pac-12), who are undefeated at home this season in 11 games.
''We stuck together through thick and thin,'' Duvivier said. ''They had their runs and we didn't let that overcome us. We just all knew we were going to win this game. We all just bought in and stuck to the game plan.''
Bryce Alford scored 18 and Norman Powell added 13 and 10 rebounds for the Bruins (11-8, 3-3).

In the first half, ''He dominated the game every way you could do it,'' Alford said.
The Beavers led 29-19 halftime and a 3-pointer by Langston Morris-Walker made it 47-30 with 9:28 remaining.
But UCLA roared back with an 18-4 run, fueled in part by timely 3-pointers and Beaver turnovers.
''We lost some shooters a few times, we turned it over a few times, got a little tentative,'' Tinkle said.
The Bruins cut the lead to two, 52-50, on a lay-in by Gyorgy Goloman with 2:35 left.
Olaf Schaftenaar responded with a 3-pointer on the next possession to give Oregon State a much-needed cushion and the Beavers held on to win.
