Iowa City West found its long-range shooting touch just in time to turn back its biggest rival.

The second-ranked Women of Troy hit six 3-pointers during a key five-minute stretch in the second half and held on to beat No. 7 Iowa City High 55-52 in a first-round Class 4A game.

West had defeated City High by margins of eight and 15 points during the regular season, but this one wasn't decided until West's Ally Disterhoft blocked City High's final 3-point shot just before the buzzer.

Tatum Klein led West with 18 points, including three huge 3-pointers to help her team get the lead for good. Mckenzie Piper added 12 points for West, Brianna Sturtz scored 10 and Disterhoft finished with seven points, six rebounds and five blocks.

City High got 12 points from Kiera Washpun and 11 each from Mickey Hansche and Haley Lorenzen. Sierra Chambers contributed eight points, nine rebounds and four blocks for the Little Hawks, while Washpun made four steals.

West struggled from the perimeter against City High's zone defense until Klein started connecting late in the third quarter. She buried a 3 from the left corner to erase City High's 34-33 lead, knocked down a 3 from the right corner to break a 36-36 tie, then hit another 3 at the start of the fourth quarter to make it 44-36, which turned out to be enough of a cushion for the Women of Troy to move on.

Disterhoft, Sturtz and Piper later hit 3-pointers to keep the Women of Troy ahead. Six of their last seven field goals came from behind the arc.

Lorenzen hit a turnaround shot to pull City High to 53-51, and her free throw with 17.6 seconds left cut the lead to 53-52. But Sturtz sank both ends of a 1-and-1 after rebounding Klein's missed free throw, meaning City High had to try a 3-pointer. Disterhoft leaped to knock it away and the Women of Troy had their victory.

West, the state runner-up last year, will take a 23-1 record into a semifinal game at noon on Friday. City High finished 17-7.
