Suddenly, the season seemed in jeopardy. That seems odd to consider during the second week of January, but in just a few weeks Arizona State basketball had shifted from national-media darling to the nation’s final unbeaten team to …

Uh oh.

Oregon State on Saturday opened a 13-point lead and the No. 11 Sun Devils were looking at a second consecutive home loss and a spot near the bottom of the Pac-12. But Shannon Evans wouldn’t let it happen.

Scoreless in the first half, the explosive senior guard scored 22 points in the second to lift ASU to a 77-75 win over the Beavers in front of a lively, and at times nervous, near-capacity crowd at Wells Fargo Arena.

Two days after losing to Oregon, ASU improved to 14-3 and 2-3 in the Pac-12. Oregon State dropped to 10-7 and 2-3.

In addition to his scoring, Evans produced six rebounds, seven assists and two steals. He shot 7 of 11 from the field, 3 of 4 from 3-point range and 5 of 6 from the foul line. His only miss at the stripe gave Oregon State one last chance to win, but Tres Tinkle missed a contested 3 at the buzzer.

Kodi Justice added 14 points for the Sun Devils. Junior De’Quon Lake had 11 points, six rebounds and three blocked shots. The Sun Devils shot 53.6 percent in the second half, rallying from 13 down in the final 11 minutes.
