CORVALLIS, Ore. — This time, Oregon State stuck to its game plan the entire second half.

Roberto Nelson scored 13 of his 22 points in the second half and anchored a stellar defensive effort that carried the Beavers to an 80-72 Pac-12 victory over Oregon Sunday night.

Eric Moreland added 15 points, 11 coming from the free throw line and had 13 rebounds for Oregon State (10-7, 2-3 Pac-12). The Beavers beat their in-state rivals at Gill Coliseum for the first time since 2010 and sent the slumping Ducks to their fourth consecutive loss.

Jason Calliste finished with 17 points and Richard Amardi had 13 points and six rebounds for the Ducks (13-4, 1-4), who trailed 37-30 at halftime and never got closer than five in the second half.

“We’re still in the process of getting to be a good team,” Beavers coach Craig Robinson said. “To watch us put it all together, albeit with some quirks here and there, it was really a fun game to watch from a coaching standpoint.”

Robinson said his team drew inspiration from last week’s 88-83 loss at home to California in a game the Beavers led 45-35 at halftime.

“I was able to point to that at halftime of this game,” Robinson said. “You can’t blow these opportunities.”

Defense was a key throughout for the Beavers, who did a particularly nice job of keeping Oregon’s Mike Moser and Joseph Young from taking over the game.

Young, who came into the game averaging a team-high 18.8 points, matched his season low with five points on 2-of-9 shooting from the field. Moser, who entered averaging 14.6, finished with eight points on 3-of-15 shooting.

For the game, the Ducks made 25 of 66 shots, including 4 of 19 from three-point range.

“Offensively, the first half we had a bunch of guys just trying to do it on their own,” Oregon coach Dana Altman said.

Sunday’s top 25

IOWA CITY, Iowa — With Devyn Marble struggling and Aaron White in foul trouble, the once-forgotten Josh Oglesby kept Iowa afloat.

Once Marble and White got it going, the 14th-ranked Hawkeyes overwhelmed Minnesota.

White scored all of his 18 points in the second half and Oglesby came off the bench to add a season-high 17 points as Iowa blew past Minnesota 94-73 on Sunday.

Oglesby led yet another brilliant effort by Iowa’s reserves, who scored 43 points.

“It’s just a further example of the talent we have across the board,” Iowa coach Fran McCaffery said. “When you’re having 40 points off the bench, it presents all kinds of problems for them.”

Marble had 15 of his 16 points after halftime for the surging Hawkeyes, who moved into third place in the Big Ten behind Michigan State and Michigan.

Iowa (15-3, 4-1 Big Ten) overcame a 10-point deficit with a 29-10 run and finished the game by outscoring the Gophers 61-30.

Andre Hollins had a game-high 20 points for Minnesota (14-5, 3-3). But Iowa held Hollins without a field goal in the second half in handing the Gophers their most lopsided loss of the season.

Saturday’s late Pac-12

PALO ALTO, Calif. — Chasson Randle shot 11 of 15 from the field en route to a career-high tying 33 points as Stanford beat Washington 79-67 Saturday night.

Stanford (12-5, 3-2 Pac-12) took a 41-36 lead into the break before Randle took over the game in the second half. After Perris Blackwell pulled the Huskies within three with 19:27 to play, Randle scored 11 of the game’s next 19 points, pushing the Cardinal lead to 54-43.

Andrew Andrews’ layup with 4:51 remaining pulled UW within 65-58, but Randle scored the first five points in a 10-2 Stanford run to put the game out of reach.
