STILLWATER, Okla. – Iowa State (18-2, 5-2 Big 12) used a 51-point first half, its best in conference play in over a year, to power past Oklahoma State (14-6, 2-5 Big 12) by a score of 84-71 on a snowy Saturday at Gallagher-Iba Arena.

For the first time since Nov. 17 against Stonehill, Iowa State had a pair of players score 20-plus. Milan Momcilovic led the way with a game-high 29 points, while Joshua Jefferson chipped in 20 of his own. For Momcilovic, it was his eighth game of the year with at least five 3-point makes, and it was also his sixth contest scoring 25-plus points. Tamin Lipsey had 13 points to go with a team-high five assists and a pair of swipes. Blake Buchanan had nine points and led the team in rebounding with nine. Killyan Toure would finish with ten points.
