Bryce Mulder had 13 points and nine rebounds, and Tanner Sixberry scored 14 poiints as the Beavers moved into sole possession of second place in the 2A GSHL.
The Beavers can clinch the No. 2 seed to district with a win over Hockinson on Tuesday.
The Beavers built a 10-point lead in the second quarter before Mulder and Sixberry got into foul trouble and went to the bench.
R.A. Long rallied to take a 37-35 lead into the fourth quarter.
“Then it was time to get in the trenches and go to war,” Woodland coach Jason Buffum said. “We felt like the last time we played (R.A. Long), we let it get away from us. So we didn’t want to do that again.”
