It was raining 3s for Helena Pueyo and the No. 12 Arizona Wildcats on Friday night at McKale Center.

Pueyo was hitting from the right, from the left — it just didn’t matter where she caught the ball from beyond the arc. It was going down.

When she’s in the zone there’s no stopping her — as Washington found out.

Pueyo scored 14 points and hit 4 of 6 from 3-point range as the Wildcats defeated the Huskies 64-53 in front of 6,381 fans.

Arizona improves to 20-4 overall and 9-4 in Pac-12 play while Washing drops to 20-4, 9-4.

UA has now won 20 games in the regular season for the first time since 2003-04, and it has swept the Huskies for first time since 2011.

Pueyo hit all of her 3s in the first half, with the first miss not coming until 4:13 left before halftime.

She made a 3 against USC in early January — before she went down with her ankle injury — and had only hit three since then.

She wasn’t the only one lighting it up as UA hit 50% (9 of 18) in the win.

Aari McDonald scored 19 points, grabbed three rebounds and dished three assists. Her streak is now at 61 consecutive games scoring in double figures — the longest active run in the nation.

Amari Carter scored 10 points (2 of 3 from beyond the 3-point line) and had two steals. Cate Reese scored 13 points and had seven rebounds.

Sam Thomas had six blocks — four in the first half — and four steals as the UA defense shut down Washington.

Dominique McBryde seemed to always have a hand on the ball on the defensive end. She ended up with three steals and numerous deflections.

Arizona took a 32-26 lead into halftime. In the first three minutes of the third quarter they extended it to an 11-point lead with a run that included a corner 3 from Carter, a put-back from Reese and a steal and a layup from McDonald.

That forced Washington to call a timeout. However, the Huskies had no answer for the Wildcats the rest of the way.

By holding UW to 53 points, UA extended its streak of holding all Pac-12 opponents under their scoring average. The Huskies’ average coming in was 67 points per game.
