DES MOINES -- Pella Christian continued a recent surge with its biggest victory yet.

The 15th-ranked Eagles made one key play after another and upset No. 2 Britt West Hancock 66-63 in a first-round Class 2A game Tuesday at Wells Fargo Arena.

Guard Jasmin Schelhaas scored 17 points to lead Pella Christian, including six straight free throws in the fourth quarter to help her team finally gain control in the back-and-forth game. Schelhaas finished 10 of 13 at the line and also grabbed six rebounds. (Boxscore)

Cali Vink hit three 3-pointers and added 14 points for Pella Christian, while Christina Nolte had nine points and three steals for the Eagles, who have won 14 of their last 15. They'll take a 22-3 record into a semifinal game against IKM-Manning at 1:45 p.m. Thursday.

West Hancock lost for the first time in 26 games. Anna Mallen led with 24 points and five steals, while Kellie Schmit had 18 points and eight rebounds. Sarah Mallen and Kaylee Weiland each had seven assists for West Hancock, which trailed most of the game before tying the score at 61 when Anna Mallen converted a three-point play with 1:43 left.

Schelhaas then was fouled on a drive to the basket and sank both free throws to break the tie. Nolte picked off a pass into the post to set up Vink's free throw, which made it 64-61, and Schelhaas drew another foul after rebounding a West Hancock miss. She again sank both shots, making it 66-61 with 21.2 seconds remaining.

Schelhaas made two free throws early in the fourth quarter after Anna Mallen's 3-pointer cut the lead to 59-58 with under three minutes to play.

West Hancock did a good job getting the ball inside early, yet never led by more than two points because Pella Christian was able to answer. West Hancock pulled to a 55-54 lead on two straight layups by Schmit midway through the fourth quarter, but Pella Christian came back with five straight points and never trailed again.

IKM-MANNING 71, BELLEVUE 55 -- IKM-Manning's Tember Schechinger filled the stat sheet in leading her team to the Class 2A semifinals.

Schechinger just missed a triple-double, scoring 23 points, grabbing 15 rebounds and handing out nine assists as the third-ranked Wolverines beat No. 14 Bellevue. IKM-Manning trailed 31-29 at halftime, but the Wolverines began the second half with an 11-2 run, then turned things over to Schechinger and let her take charge the rest of the way.

A Northwest Missouri State recruit, Schechinger scored 14 of her team's 18 points as IKM-Manning built an insurmountable lead. She also finished with five steals and two blocks and committed just one turnover. (Boxscore)

Kaylee Blake added 12 points and freshman Morgan Muhlbauer scored 10 for IKM-Manning, which will take a 24-2 record against No. 15 Pella Christian in a semifinal game at 1:45 p.m. Thursday.

Schechinger was simply too much for Bellevue in the second half and the Comets lost for the first time in 26 games. Kelsey Ernst led Bellevue with 19 points and 10 rebounds and Ali Reeg scored 14 points to go with seven assists. Carly Rubel led Bellevue with 12 rebounds and scored four points.

IKM-Manning had a lot of success with the 5-foot-10 Schechinger posting up on the block. All six field goals she scored during her key second-half stretch came on layups, turnaround shots or putbacks.

Her follow-up basket gave the Wolverines a 61-47 lead with 5:33 left, but she went to the bench 10 seconds later after picking up her fourth foul. She was out for a little more than a minute, during which time Bellevue cut the lead to 61-53.

When Schechinger returned, she immediately pulled down a rebound, then came up with a steal. Moments later, she sank two free throws to restore the lead to 10 points and start a 7-0 run that put it out of reach.
