CORVALLIS — Calvin Haynes hit a high-arcing shot with 6 seconds left in overtime to give Oregon State a 71-70 win over Vermont in Monday's quarterfinals of the College Basketball Invitational tournament.

Haynes led the Beavers (15-17) with 19 points and Roeland Schaftenaar added 14 points and 10 rebounds.

"That last possession we drew up is the same one that we always draw up," said Haynes, "a pick and roll to me an Roeland (Schaftenaar) up high and Rickey (Claitt) told me, he said, 'Don't settle for the jumper, go straight to the basket and either get fouled or make it.' I pretty much did that. I just threw it up and prayed to God that it would go in and it went in."

Marqus Blakely had 17 points, seven rebounds and four steals for the Catamounts, who finished 24-9. Senior guard Mike Trimboli added 15 to finish his career with 2,008 points.

Oregon State will host Stanford in the CBI semifinals on Wednesday. The schools have already met three times this season, with the Beavers sweeping the regular season meetings and the Cardinal getting revenge in the Pacific-10 Conference tournament.

The Beavers trailed 38-36 at the half and fell behind by as many as seven in the second half. But Claitt spurred a comeback by making three 3-pointers, the last giving Oregon State a 67-65 lead with about a minute left.

Vermont evened the score when Blakely made a lay-in off an alley-oop pass from Trimboli with 34 seconds to go.

The score stayed that way until an overtime in which both teams were ice cold.

"They banked in shots, we scored, and then they would go bank some more shots in, but I felt we never let them take a shot that wasn't contested," said Oregon State coach Craig Robinson. "They rose to the occasion. Rickey (Claitt) hit some important shots, we had a couple steals and we didn't give up. When we fell behind, our guys said, 'Let's do what we need to do,' and they did. We did what we needed to do, and that was to win a close game."

Trimboli hit a 3-point shot with 21 seconds left for Vermont's only score of the extra period.
