A letdown may have been inevitable.

Fortunately for Iowa State, Melvin Ejim provided a record-setting lift Saturday, propelling the Cyclones to an 84-69 men’s basketball victory over Texas Christian — and placing himself atop the Big 12’s single-game scoring list.

The 6-foot-6 senior finished with 48 points — eclipsing a conference mark of 44 shared by former Kansas State stars Denis Clemente and Michael Beasley — and grabbed a career-best 18 rebounds.

“I was a little bit shocked,” Ejim said after hitting 20-of-24 shots. “We were just playing. I wasn’t really looking up and seeing how much I had.

“These guys just kept telling me to be aggressive, keep playing.”

Ejim’s performance helped No. 16 Iowa State improve to 18-4 overall and 6-4 in the Big 12.

It was a nice follow-up to Monday’s dramatic triple-overtime win at Oklahoma State.

“Actually, I wanted to get the ball and score myself,” Iowa State forward Georges Niang deadpanned, “but Melvin just kept shooting.”

The Cyclones were able to laugh after a few tense moments against TCU (9-13, 0-10).

Kyan Anderson led the Horned Frogs with 27 points, and kept the Big 12’s last-place team within striking distance until the final minutes.

“It’s not every day somebody comes out and scores that many points,” Anderson said of Ejim. “It’s hard to say what could have happened if he didn’t, because he did.”

Ejim accounted for 20 straight Iowa State points, starting with two free throws at the 9-minute mark and ending with a jumper and another free throw at 2:36.

“I think one play that stands out to me is, Georges has a layup, turns around and pitches out to me,” Ejim recalled. “These guys saw I was having a good night and they really looked out for me.”

Ejim finished with the second-best scoring effort in Cyclone history, behind Lafester Rhodes’ 54 against Iowa in 1987.

“What can you say?” Iowa State coach Fred Hoiberg asked. “Just the efficiency of his game. He got behind the zone on several occasions. A lot of lob passes up to him. He’s a great finisher.”

The Cyclones made 32 baskets on 27 assists, while shooting 53.3 percent.

But it was Ejim who had a Hilton Coliseum crowd of 14,384 chanting his name.

“This will get a lot of national attention,” said Hoiberg, who once scored 41 points as a Cyclones player. “There have been some pretty special players who have gone through this league.”
