Cedar Rapids Xavier emerged from a wild fourth quarter against Grinnell to claim a berth in the Class 4A semifinals.

Sixth-ranked Xavier let most of a 12-point lead slip away before holding behind some clutch shooting to turn back third-ranked Grinnell 60-55.

Grinnell twice pulled within two points and then cut the lead to one, but could never get the lead because the Saints kept answering with a big score of their own. 

Senior guard Kiana Stanek, who came into the game averaging 7.6 points, led Xavier with 22 points. Lexi Noonan added 12 points for the Saints and Kyle Brown scored 10.

Junior forward Sienna Durr was outstanding for Grinnell, scoring 26 points on 9-for-14 shooting, making all eight of her free throws and pulling down 11 rebounds. Kyra Hungerford added eight points for the Tigers and Kameron Moore scored seven.

Xavier led 43-31 going into the fourth quarter and appeared to be in control. But Grinnell scored the first seven points of the final period and Xavier found itself in a battle until the end.

A key moment occurred with Xavier clinging to a 49-47 lead with under a minute to play. Stanek got the ball on the right wing and, with her body twisted at an odd angle, hit an off-balance 3-pointer with 1:40 left for a 52-47 lead.

Then, after Grinnell cut the lead to 54-53 on Hungerford's 3 with 25 seconds remaining, Stanek sank two free throws, Noonan followed with another pair and the Saints had the margin they needed to move on.

Xavier takes an 18-6 record into a semifinal at 10 a.m. Friday against eighth-ranked North Scott. Grinnell winds up 19-5.
