SEATTLE (AP) — David Crisp scored 16 of his 21 points in the second half, Matisse Thybulle added 15 points and Washington pulled away in the second half for a 77-61 win over Cal Poly on Tuesday night.

Washington (6-5) rolled in the second half thanks to a defensive effort that made up for a sluggish first 30 minutes offensively. The Huskies entered the night averaging nearly 87 points per game but Cal Poly lengthened possessions and forced Washington to work at the offensive end.

But Washington’s defense over the final 20 minutes was possibly the best it’s been all season. The Huskies went on a 12-2 run midway through the second half capped by Crisp’s third 3-pointer of the half to take a 58-48 lead with 7:36 left.

Ridge Shipley led Cal Poly (5-7) with 14 points, but the Mustangs went more than eight minutes of the second half with just one field goal.

Markelle Fultz scored 14 points, just the third time in 11 games he’s scored under 20 points. Noah Dickerson added 12 points — including a two-handed dunk off a nifty spinning wraparound pass by Fultz — and grabbed 10 rebounds. But it was Dickerson’s work defensively in the second half against shorter perimeter players that was critical.

Cal Poly was seeking its seventh win all-time against a Pac-12 opponent and first since beating UCLA in November 2012. The Mustangs put a scare into Washington in the first half, leading by as many as 10 before a 14-5 run over the final four minutes of the half pulled the Huskies within 37-36 at the break.

The Mustangs were 9 of 18 on 3-pointers in the first half but went silent over the final 20 minutes hitting just 1 of 10 on 3s. Luke Meikle’s 3-pointer with 2:44 left was Cal Poly’s first of the second half.
