Pella's Ciara Buchheit never has to worry about getting enough arch on her shots. She gets plenty.

The 5-foot-9 senior hit two rainbow 3-pointers during a second-half run that turned the game around and enabled fourth-ranked Pella to beat No. 5 Lewis Central 47-43 to complete the quarterfinal round in Class 4A.

Pella outscored Lewis Central 12-1 during the burst, erasing a 26-24 deficit and building a 36-27 lead late in the third quarter. The Lady Dutch had to battle the Titans throughout the fourth quarter, but they had the cushion they needed to stay ahead.

Buchheit finished with nine points and eight rebounds for Pella, the state runner-up a year ago. Kiara Bradley led the Lady Dutch with 18 points and Katie Vander Molen added nine.

Lewis Central, in the tournament for the third time in five years, got 17 points and eight rebounds from freshman Megan Witte. Maegan Holt scored 11 for the Titans and Alissa Pomrenke had seven.

Down 10 early in the fourth quarter, Lewis Central ran off six straight points to cut the lead to 39-35 but could not get any closer. Vander Molen sank two free throws and Chloe Van Vliet got loose for two fastbreak layups, stretching the lead to 45-36 with 1:30 left.

Lewis Central again got within four with just under a minute to play before Bradley came up with a key steal in the closing seconds to help thwart the Titans, who had won 18 straight.

Pella improves to 20-4 heading into a semifinal game at 11:45 a.m. Friday against top-ranked Marion. Lewis Central finishes 22-2.
