Hard to imagine a 6-foot-10, 245-pounder could get lost on a basketball court.

“That’s true,” Oregon State freshman guard Calvin Haynes acknowledged.

But the Beavers have yet to find California’s Ryan Anderson in four tries. The sweet-shooting sophomore averages 18.8 points and 11.3 rebounds vs. OSU, so holding him to mere mortal numbers tonight is paramount for OSU (6-15, 0-9) to end a school-record 11-game tailspin.

Tipoff is set for 7:30 p.m. at Hass Pavilion.

“Everybody is like, how did you lose him?” Haynes said after Tuesday’s practice. “Good players make good plays. We have to keep our hands on him, and that’s what we’re gonna do.

“We aren’t losing him this game, we’ll stay with him. We have to keep our head on a swivel, stay with our man and do our defensive assignment.”

Anderson averaged 30 points and 13 rebounds in victories at Washington State and Washington and earned Pac-10 Player of the Week honors. He was likewise the ESPN.com, Sporting News and FoxSports.com national Player of the Week.

He hit 20 of 32 shots overall, was 9 of 14 on 3-pointers and 11 of 11 at the line. He had 33 points and 17 rebounds against Washington and 27 points and nine rebounds against WSU.

“Monster,” Haynes said. “He’s a good player, I respect his game a lot. But it’s what we do, and not what he does.”

The Beavers conclude the trip at 5 p.m. Saturday at Stanford. They are 0-14 at Maples Pavilion since a 77-66 victory there on Jan. 7, 1993.

OSU is 0-9 in Pac-10 play for the first time ever, and is trying desperately to avoid the dubious distinction of being the first Pac-10 team to get skunked completely. Oregon (1972) and USC (1976) were 0-14 in the Pac-8, but since the 1978-79 expansion only WSU — which was 1-17 in 1983, 1990, 2002 and 2002, has seriously flirted with an 0-18 bagel.

“I think we’re gonna get a win. Not a win, but a couple wins going into the Pac-10 tournament,” Haynes said. “We’re just trying to get over that slump, the last five minutes, not making mistakes and executing.

“(The Oregon game) put us over the hump, it taught us a valuable lesson of taking care of the ball and playing defense on every possession. I think we can go to Cal and get a win, go to Stanford and get a win.”
