KANSAS CITY, Mo. — First Iowa State cut into the Kansas State Wildcats' lead, then Marial Shayok cut their hearts out.
Shayok's back-to-back 3-pointers from the right corner got the Cyclones even with less than 2:53 left, then put them in front for good exactly a minute later Friday night as Iowa State rallied late for a 63-59 Big 12 Tournament semifinal victory over K-State at Sprint Center.
It was a heartbreaker for the Wildcats, who erased a 10-point halftime deficit to lead by five, 55-50, on a Barry Brown jumper with 2:45 to go, only to see Iowa State close the game on a 13-4 run.
Shayok had 21 points to lead the Cyclones, who improved to 22-11 heading to Saturday's 5 p.m. final. Iowa State also got 12 points from Nick Weiler-Babb, including two free throws to start the late run, plus eight points and 16 rebounds from Michael Jacobson.
All five starters scored in double figures for K-State (25-8), led by Cartier Diarra with 15 points, Brown 13, Xavier Sneed 11 and Makol Mawien and Kamau Stokes with 10 each.
In a back-and-forth game with a NCAA Tournament atmosphere, K-State came back to tie the game at 38 on a Diarra 3-pointer with 15:01 left. Talen Horton-Tucker's layup and a Lindell Wigginton 3-pointer put Iowa State back up by five, but then it was the Wildcats' turn.
Brown answered with a three, Diarra's free throw at the 12:16 mark cut it to 43-42, and a Xavier Sneed corner 3-pointer to beat the shot clock gave K-State the lead. Weiler-Babb tied it for Iowa State, but consecutive baskets by Mawien and Brown gave K-State a 49-45 advantage, prompting Iowa State to call time with 9:34 to go.
Back-to-back baskets from Mawien and Brown again put K-State up five, but that was the end for the Wildcats, who scored just four points over the last 2:45.
K-State hit its first three shots of the second period, including back-to-back 3-pointers from Stokes and Diarra, then cut Iowa State's 10-point halftime advantage to 38-35 on Stokes' two free throws with 17:32 to play.
Iowa State turned the ball over four times in first four minutes and K-State tied it at 38 on Diarra's second three of the half with 15:01 to play.
Iowa State held a 35-25 halftime advantage.
After a hot start that included a seven-point lead midway through the half, K-State suddenly went cold as Iowa State closed the half with a 13-2 run over the last 5:17.
The Wildcats made just 1 of their last 15 shots of the period, a pull-up jumper in the lane by Brown at the 1:21 mark that trimmed the lead to six, but Wigginton scored the last two baskets to give ISU its first double-digit lead.
K-State led 21-14 on Stokes' reverse layup with 10:05 left in the period, but managed just four points the rest of the way. Iowa State had eight turnovers in the first 12 minutes, but none the rest of the half.
Shayok led the Cyclones at the half with 11 points, while Jacobson had eight to go with six rebounds. Iowa State shot 50 percent to 30 for K-State in the period and outrebounded the Wildcats 23-14.
Diarra had eight points in the half and Stokes five for K-State.
