BUTTE — MSU-Northern and Montana Western pulled a pair of upsets Saturday at the Butte Civic Center to wrap up the quarterfinal round of the Frontier Conference women’s basketball postseason tournament.

The fifth-seeded Skylights started the day with a red-hot shooting performance to down No. 4 Rocky Mountain College 82-74. Western, the sixth seed, used a third-quarter surge to defeat No. 3 Carroll College 65-56.

MSU-Northern 82, Rocky Mountain College 74

MSU-Northern sizzled in the first quarter, making seven 3-pointers to take a double-digit lead, and put together a crucial third-quarter run to get past Rocky and advance to the semifinal round.

Becky Melcher splashed four 3s in the first 10 minutes, and Taya Trottier, Canzas HisBadHorse and Shania Moananu added one apiece as the Skylights built a 29-13 lead. Melcher scored 14 first-quarter points and finished with a game-high 30 on 10-of-19 shooting (7 of 15 from 3-point range). She added 11 rebounds, a blocked shot and three steals to her stat line.

Rocky battled back to tie the game at 36-36 in the second quarter on a Brenna Linse basket, but MSUN responded with consecutive triples from Trottier and Melcher and took a 44-38 lead into halftime. The Bears eventually stole the lead back in the third quarter following a 9-0 run capped be an Isabelle Heggem bucket.

But the Skylights again answered — this time with a 13-2 run to take a 60-51 lead. MSUN led 66-59 going to the fourth and wouldn’t trail the rest of the way. The Skylights trailed for less than two total minutes of the game.
