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.

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.

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 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.
