Kelsey Bolte bounced back from her worst shooting game of the season with 20 points and No. 22 Iowa State rolled to its third straight victory Wednesday night, 79-59 over Oklahoma State.

Hallie Christofferson added 15 points for Iowa State (16-5, 4-3 Big 12) and Anna Prins scored 14, all but two in the second half. After struggling offensively in their first four conference games, the Cyclones have topped 70 points in their last three, the first time they've put a string like that together in league play since 2005.

Oklahoma State (13-7, 1-6) got a career-high 24 points from 6-foot-6 freshman Vicky McIntyre. McIntyre made 10 of 17 shots with a variety of post moves, but her teammates shot just 11-for-45.

Bolte made only 5 of 20 shots and was 0-for-7 from 3-point range a 71-56 victory over Missouri last Saturday. But she made all four of her 3-point shots in this one and finished 6-for-9 overall. She also grabbed nine rebounds.

Iowa State led 40-30 after a first half constantly interrupted by whistles. The officials called 27 fouls in the half, 16 on Oklahoma State.

The 6-7 Prins, who had been counted on to counter McIntyre, picked up two quick fouls and played only four minutes in the half. She returned for the start of the second half and helped the Cyclones take control.

Iowa State made six of its first nine 3-point shots in the half in building a 65-41 lead. Prins scored 10 points in the surge, including a 3-pointer. Bolte and Christofferson each knocked down a pair of 3s and reserve Kelsey Harris added one.

Christofferson cut across the lane and took a pass from Amanda Zimmerman for layup that gave Iowa State its biggest lead, 69-43 with 9:40 left. That enabled coach Bill Fennelly to rest his starters down the stretch.

Tiffany Bias 13 points for Oklahoma State, which starts two freshmen and two sophomores. The Cowgirls stood 12-1 on Jan. 4, but they've won only once since then.
