CORVALLIS — Calvin Haynes says he wants to be the guy who takes the big shots for Oregon State.

On Saturday he was that guy, hitting a key 3-pointer and a layup down the stretch as the Beavers beat California 65-54.

The victory snapped a four-game winning streak for the Golden Bears (20-7, 9-5 Pacific-10 Conference), who are seeking their first NCAA tournament berth in three seasons.

Oregon State (13-13, 7-8) won its third straight conference game and swept the season series against Cal for the first time since the 1994-95 season.

The Golden Bears led by as many as 12 points early in the second half, but the Beavers went ahead midway through on Haynes' jumper. Oregon State held on to just slight edge the rest of the way until stretching the margin to 57-50 Haynes' 3-pointer and a layup.

It was the 3-pointer, which Haynes made with a defender in his face, that put the crowd at Gill Coliseum on its feet.

"I knew Calvin was going to make that shot," coach Craig Robinson said. "That's the kind of shot he loves."

Said Haynes: "I take the tough ones."

Theo Robertson had 14 points for California, while Jamal Boykin had 11 points and seven rebounds.

The Golden Bears, coming off a 78-60 victory at Oregon, did not have 7-foot center Jordan Wilkes, who suffered a concussion in the first half of the game Thursday. Sophomore Harper Kamp made his first start his Wilkes' place.

The Golden Bears had defeated the Beavers in seven straight meetings before Oregon State pulled off a 69-65 victory in Berkeley on Jan. 22.

In the rematch, Oregon State went on a 9-2 run in the first half, capped by Lathen Wallace's free throws, to go up 13-7. Jerome Randle answered with a 3-pointer for Cal.

That touched off a 19-2 run for the Golden Bears that made it 26-15 after D.J. Seeley's jumper.

Cal led 28-21 at the half. Patrick Christopher's 3-pointer and Robertson's layup extended the margin to 33-21 early in the second half.

Oregon State got within 40-38 on Haynes' jumper and tied it on Calvin Hampton's layup. But the Beavers were unable to pull ahead until another Haynes jumper made it 44-42 with 9:13 to go.

"He just jumps up and shoots it," Cal coach Mike Montgomery said about Haynes. "He can create his own shot. He makes those things, and that really hurt us."

Randle, who led Cal in scoring with an average of 18.4 points per game, was held to just three points.

Wallace finished with 12 points for the Beavers, who were coming off a 66-54 victory over Stanford. Oregon State has seven conference wins after going 0-18 in the Pac-10 last season.

Roeland Schaftenaar had a good all-around performance for the Beavers, with eight points, eight rebounds, five assists and three blocks.

"We're a good team, but all good teams have to have someone they look to when times are tough, and he's that guy," Robinson said about the 6-foot-11 center.

Oregon State's dramatic improvement is largely credited to Robinson, President Barack Obama's brother-in-law, who was hired in the offseason after two years at Brown.

Former Oregon State coach Jay John, let go in the midst of last season, is an assistant coach at Cal under Mike Montgomery.

The Beavers, coming off a 66-54 victory over Stanford, swept the San Francisco Bay Area teams for the first time since the 1989-90 season.

It was Oregon State's final home game of the season. The Beavers visit rival Oregon next Saturday, before wrapping up the season on the road against UCLA and USC.

Cal hosts the Los Angeles schools next week before visiting Arizona and Arizona State to conclude the regular season.
