TOURNAMENT BRACKETS

WEST REGIONAL

Chandler AZ 77, Niwot CO 63

The Wolves advanced to the round of eight for the fifth straight time, but Arizona Division 1 champion Chandler needed to rely on a 42-11 edge in the field events in order to overcome being swept by the Cougars in the 800, 1,600 and 3,200 meters behind the combined efforts of Taylor James, Madison Shults, Mia Prok, Tessa Everett and Princeton commit Lucca Fulkerson. Niwot, the Colorado 4A champion, also received a win from the Stanford-bound James in the 400 meters, along with Kimora Northrup in the 300-meter hurdles, and prevailed in both the 4x400 and 4x800 relays, tough matchups for Chandler after Niwot secured both titles at The Outdoor Nationals, presented by Nike, at Hayward Field in Eugene, Ore. But the Wolves, who had never won a first- or second-round matchup by fewer than 20 points in tournament history, had junior Trinity Henderson secure victories in the 100 and 200, along with contributing to a win in the 4x100 relay. Sheena Cumberbatch swept the long jump and triple jump, Indiana signee Makayla Hunter doubled up in the discus throw and shot put, with Erykah Garrett capturing the 100 hurdles and placing runner-up in the 300 hurdles for Chandler.

Boise ID 70, Long Beach Poly CA 66

For the first time in either gender in tournament history, a team from Idaho advanced to the regional semifinals, with 5A champion Boise rallying for the overall victory by winning the 4x400-meter relay, an event Long Beach Poly has dominated for the past two decades, including the 2004 national high school record 3:35.49 at the California state championship meet in Sacramento. Boise prevailed by a 3:56.47 to 3:58.13 margin in this matchup to produce the come-from-behind win after the Jackrabbits held a 38-16 margin in the field events, including a sweep of the long jump. Iowa signee Jade McDonald was exceptional again for Long Beach Poly, winning both the 100 hurdles and 300 hurdles, along with the triple jump, and placing second behind teammate Lauren Reed in the long jump. The Jackrabbits, who captured their 21st Southern Section title this season in the absence of a California state final, also had Destiny Okoh double up in the discus throw and shot put, with Zharia Taylor winning the high jump. But despite a 100 win from Anayah Wyche and 200 triumph by freshman Taylor Johnson, Long Beach Poly managed to score a combined one point in the 400, 800, 1,600 and 3,200. Boise had junior Logan Smith win the 400 and 800, with freshman Samantha Smith taking the 1,600 and 3,200, supported by fellow ninth-grader Allie Bruce and Gonzaga commit Rosina Machu. Junior Ani Smith also led a pole vault sweep for Boise.

Buchanan CA 89, Valor Christian CO 47

The Bears became the first California girls team to advance to the round of eight multiple times in tournament history, relying heavily on a 45-9 margin in the field events against a Valor Christian group that fell in the second round after making it to the regional semifinals in 2018 and 2019, before being knocked off on both occasions by DeSoto High from Texas. Buchanan, which captured its 11th Central Section title without the presence of the California state final for the second year in a row, received victories in the discus throw and shot put from junior Chinyere Egbuziem, a pole vault triumph from Jordan Leveque and wins in the long jump and triple jump from Lauren Fowler and Helen Chu, respectively. Fowler, a New Mexico signee, prevailed in an exciting 100-meter showdown against Stanford commit Camille Peisner, who contributed heavily for the Colorado 5A champions by winning the 200, 400 and being a catalyst on the victorious 4x400 relay. Reese Dragovich, a Hillsdale College commit, earned the 800 win and freshman Farrah Eike triumphed in the high jump for Valor Christian, but Buchanan showcased superior depth in the 1,600 and 3,200, led by sophomore Sydney Sundgren. It was a split decision in the hurdling events, with junior Kylie Bahr securing victory in the 300 hurdles for Valor Christian and Fresno State signee Alexa Dandridge taking the 100 hurdles for the Bears, in addition to anchoring the winning 4x100 relay.

DeSoto TX 71, Waukee IA 56

DeSoto joined Chandler High of Arizona in reaching the regional semifinals five times, earning a second victory against Iowa 4A winner Waukee, including a 76-42 triumph in the opening round of the 2017 tournament. The Warriors made history by becoming the first program in either gender from Iowa to secure a first-round victory, but the absence of the triple jump from their lineup, combined with Texas 6A champion DeSoto sweeping the 4x100 and 4x400 relays were too much for Waukee to overcome. DeSoto was dynamic, as always, in the sprints and hurdles, with Ja’Era Griffin winning the 100 and 200, Amelliah Birdow capturing the 400 and USC commit Jalaysi’ya Smith sweeping the 100 hurdles and 300 hurdles. Their performances neutralized the usual strengths of Waukee, including juniors Mackenzie Carney and Natalie Harris, in addition to senior Sehansa Karunatilaka. The Warriors did receive wins in the 1,600 and 3,200 from Margaux Basart, in addition to a victory in the 800 by Molly Bannister. But it was a Mia Abraham victory in the long jump for the Fighting Eagles, combined with the uncontested sweep of the triple jump, that helped offset Waukee winning the high jump with Layanna Green, the discus throw with Avelyn Burger and the shot put with Ava Smith. Neither team competed in the pole vault.

EAST REGIONAL

Miami Northwestern FL 75.5, Mentor OH 65.5

Like DeSoto High from Texas and Chandler High of Arizona, Miami Northwestern also moved on to the elite eight for the fifth time, but the Bulls were challenged significantly by Ohio Division 1 winner Mentor. Miami Northwestern, a 17-time Florida 3A champion, had prevailed against Bullis School from Maryland by a 69-58 margin in the second round in 2018, but this was the toughest test in order to advance to the regional semifinals in tournament history for the Bulls. Mentor followed a trend of Ohio representatives being eliminated by Florida powers, with Lincoln losing to St. Thomas Aquinas in 2018 and Withrow falling to Miami Northwestern in the second round in 2017. A big key to Miami Northwestern’s success was neutralizing the scoring potential of North Carolina signee Paige Floriea, as junior Aaliyah Butler beat the versatile Mentor standout in the 100, 200 and 400 in three exciting showdowns. Floriea did win the long jump for the Cardinals, but the Bulls also added sweeps in the 100 and 300 hurdles, highlighted by victories from Jaylah Milfort and Breanna Moss, along with securing victories in the 4x100 and 4x400 relays. Sophomore Savannah Dennison doubled up in the 1,600 and 3,200, with senior Rylee Yocum capturing the 800 and the two athletes also contributing to a 4x800 victory for Mentor, which had Youngstown State signee Victoria Lanese prevail in the high jump to support an uncontested pole vault sweep. Junior Me’Kayla Rothmiller came through with a pair of strong performances in the discus throw and shot put for the Bulls.

Hoover AL 84, Brentwood TN 57

For all the success Alabama boys teams have achieved in tournament history, including Hoover winning the championship in 2018 after Auburn High secured the title in the inaugural event in 2016, this victory marks the first time any girls program from the state has advanced past the second round. Hoover had lost to Western Branch High from Virginia by an 89-47 margin in its previous appearance in the round of 16 in 2018, but thanks to South Florida commit Chakiya Plummer and sophomore Jebreiya Chapman in the hurdles and sprints, the Buccaneers remained in control throughout against Division 1 large school champion Brentwood, which became the first Tennessee girls team to earn an opening-round victory in event history. Kaitlyn Vanderkolk, a Belmont University signee, won the 1,600 and 3,200 and Sofia Rutherford secured the 800 in addition to both athletes contributing to a 4x800 relay victory for Brentwood. But the versatile junior Hollan Powers managed the only other wins for the Bruins in the long jump and shot put, as Kayla Jemison countered those victories for Hoover by capturing the high jump and triple jump. Taniyah Thomas took the discus throw and Kirsten Leonard prevailed in the pole vault for the Buccaneers, who also earned wins in the 4x100 and 4x400 relays.

Union Catholic NJ 72.5, Rosemount MN 68.5

The Vikings, who dominated Non-Public A competition at their group meet in New Jersey before excelling again at the Meet of Champions, needed to rely on a sweep of the 4x100, 4x400 and 4x800 relays to advance to the regional semifinals for the fourth time. Union Catholic, whose only second-round loss came in a 71-65 setback in 2018 to Marietta High of Georgia, was pushed to its limit by a balanced Rosemount lineup that won five events each on the track and in the field. The Minnesota Class AA champions, who joined Minnetonka in 2018 in advancing to the second round, benefited from University of Wisconsin soccer commit Mackenzie Jacobson winning the 100 and 200. Jenna Johnson supported Jacobson with a victory in the 400 and Taylor Heimerl took the 800 for Rosemount, which also had junior Ava Cinnamo triumph in the triple jump and the intermediate hurdles. Sophomore Jordan Hecht doubled up in the discus throw and shot put for the Irish, with seniors Ashley Cridlebaugh and Olivia Passeri earning wins in the high jump and pole vault, respectively. It was a group of sophomores who accounted for many of Union Catholic’s victories, with Alexandra Bonn prevailing against Jacobson in the long jump, as well as Ajanae Thompson in the 100 hurdles and Kaleigh Gunsiorowski in the 1,600. Junior Abby Granrath contributed valuable points for the Vikings by taking the 3,200 and placing second in the 1,600. Despite Rosemount winning more individual events, Union Catholic still managed to prevail overall by scoring in every competition and producing a significant momentum shift with its relay sweep.

St. Thomas Aquinas FL 113, Indianapolis Cathedral IN 19

The Raiders already held the record for the most lopsided second-round victory in tournament history with their 70-point triumph in 2019 over Homewood-Flossmoor High from Illinois, but Florida 4A champion St. Thomas Aquinas looked nearly flawless against Indianapolis Cathedral, which could only earn one win overall from sophomore Kailee Swart in the pole vault. In addition to losing three relays, the Irish were also swept in the 100, 200, 1,600 and 3,200, with 15 of their points coming from the field events. Reese Sanders managed to score in the 400, 800 and shot put for Indianapolis Cathedral, with Alexis Parchman finishing second in the long jump and Katie Bremer placing runner-up in the high jump, as the Irish joined Warren Central in 2016 and 2017 in representing Indiana in the second round. Sophomore Cha’iel Johnson doubled up in the 400 and 800, with freshman Lindsey Duffner sweeping the 1,600 and 3,200 for St. Thomas Aquinas, which also received victories from Coastal Carolina signee Alexis Glasco in the 300 hurdles and 100-meter dash, as well as North Carolina-bound Eddiyah Frye in the 100 hurdles and long jump. Freshman Lauren Thomas triumphed in the discus throw and shot put, with junior Endeyah Lane capturing the 200 and sophomore Leya Armenteros-Castillo earning the high jump win for the Raiders, who advanced to the round of eight for the third time overall.
