The Horizon girls basketball team has had a lot of great wins this season, but Thursday’s was undoubtedly the sweetest thus far.

Horizon (16-5, 10-1 Big Sky) upset Arlington (15-5, 10-1), then a nine-seed in 1A girls basketball, in a game Thursday in Arlington that was moved up from Friday due to inclement weather. The Hawks edged the Honkers 47-46 in a back-and-forth thriller, becoming the first team in the Big Sky to take down Arlington. The win, combined with other results from Big Sky competitions this weekend, gave Horizon a guaranteed berth for the second year in a row in the Big Sky district tournament Feb. 17-18 in Madras.
