Melvin Ejim hit 20 of 24 shots in scoring a Big 12-record 48 points and grabbed a career-high 18 rebounds to lead No. 16 Iowa State to an 84-69 victory over TCU on Saturday.

Ejim had two 3-pointers and six dunks during his big game, one on a spectacular fast-break lob from DeAndre Kane that gave the Cyclones (18-4, 6-4 Big 12) a 67-52 lead and effectively put the game out of reach.

A 6-foot-6 senior, Ejim scored 20 straight Iowa State points during one stretch in the second half. It was his 30th career double-double.

Georges Niang added 11 points and Kane finished with 10 assists for the Cyclones, who avoided a letdown after their thrilling three-overtime victory at Oklahoma State on Monday, their first win in Stillwater since 1988.
