A season of historic parity in women’s basketball continued on a thrilling Sunday, as three top-15 teams fell in thrilling fashion, including Caitlin Clark and the third-ranked Iowa Hawkeyes. Meanwhile, Stanford coach Tara VanDerveer became the winningest coach in college basketball as the No. 8 Cardinal bested Oregon State 65-56.

Here’s a look back at the biggest storylines from a Sunday slate of women’s basketball.

Ohio State over Iowa despite Caitlin Clark’s 45 points
Stepping onto the floor to begin the fourth quarter, No. 3 Iowa’s Caitlin Clark set out to squash Ohio State’s spirited upset bid, nailing a three before dropping a dime to Molly Davis. Iowa’s lead grew to 70-58 and it appeared the Buckeyes, like nearly everyone who squares up against Iowa, couldn’t keep up with their high powered attack. But No. 18 Ohio State’s handsy defensive identity — the Buckeyes force nearly 21 turnovers a game — resurfaced in crunch time, as three crucial takeaways powered Ohio State to a 25-13 run to end regulation, and the Buckeyes ultimately cruised in overtime to a massive 100-92 win over Iowa.

Despite the loss, Iowa star Caitlin Clark finished with one of her best career performances with 45 points, just one off matching an all-time high, and seven rebounds. A pair of first-quarter triples from Clark helped the Hawkeyes build an early four-point cushion. But it was Cotie McMahon who owned the first quarter, totaling 11 points, including the afternoon’s very first basket, and helping the Buckeyes stay within just two against the sharp-shooting visitors.The Buckeyes managed retake their lead on moments into the second period on a Taylor Thierry triple, and after a brief Iowa run ahead of the intermission, OSU’s Jacy Sheldon continued an excellent afternoon with another crucial triple before the halftime horn to pull the Buckeyes back within a possession — Sheldon had a splendid 24 points and seven boards.

A pair of unlikely contributors stepped up for Iowa to build much-needed separation from a relentless Buckeye team as Addison O’Grady and Sydney Affolter — the two entered Sunday with just over 10 points per game combined — were the only scorers in a quarter-ending 12-6 run, with the Hawkeyes leading 65-58. Clark’s aforementioned magic to begin the fourth quarter dug a near impossible hole for the Buckeyes — trailing by 12, ESPN Analytics gave OSU just a 3.5 percent chance of victory — but McMahon regathered the reins on a dominant 33-point, 12-rebound performance, converting a gritty and-one to spark Ohio State’s late rally and scoring 13 points in the final quarter of regulation.

McMahon’s layup and a jumper from Celeste Taylor inside the final minute brought Ohio State all the way back, leading 82-81, but it all appeared for naught as Hannah Stuelke was fouled with nine seconds remaining and a chance to win the game. The Iowa forward split the pair, however, and the heavyweight showdown barreled on toward overtime. A hot shooting night for the Buckeyes — OSU shot a scintillating 11-22 on the afternoon from three — peaked in overtime, as the home squad made 83 percent of their field goals in the extra period and dominated OT by a margin of 17-9.

Chaos in ACC as top-15 powers unseated
Entering Tallahassee without an ACC victory on the season and without an AP top-25 road victory in well over a decade, Virginia and its star point guard Kymora Johnson, who led all scorers with 33 points, moved mountains of historical precedent Sunday in a stunning 91-87 victory over No. 15 Florida State.

Johnson teamed up with Paris Clark to spark a hot Cavalier start, with the pair scoring or assisting at UVA’s first six points as the visitors surged to an early 11-1 lead. UVA managed to maintain a five-point lead after the opening quarter of play, but an uncharacteristic struggle with giveaways — the Hoos are among the 25 best teams nationally in turnover rate — saw Virginia lose possessions eight times in the second quarter as Florida State trotted into the locker room leading by four. FSU’s Alexis Tucker nailed a jumper to give the ‘Noles a game-high eight-point lead, but Johnson rallied back with a near single-handed 12-4 run and the teams entered the final quarter deadlocked at 65. Florida State fell behind as much as nine in the fourth quarter, and while a Ta’Niya Latson layup trimmed the deficit to two in the final seconds, Johnson was a perfect 4-4 at the line late to maintain UVA’s two-possession advantage.

Meanwhile, No. 23 North Carolina scored a massive victory to break into the ACC title race, as Deja Kelly’s 23-point, six assist evening dealt No. 13 Louisville its first conference blemish 79-68 from Carmichael Arena. Lexi Donarski started the afternoon on fire for the Heels, scoring the first 10 points of the afternoon for UNC, and the home team’s defense allowed just two points in the final 4:45 of the first quarter to take a 22-13 lead. Louisville imposed the inverse on the hosts to start the second quarter, yielding just one field goal in the first five minutes, and the teams battled closely through halftime and deep into the third quarter.

Tied at 47 and struggling with her shot, Kelly opted to push the issue against Louisville’s defense and earned her way to the foul line time-and-time again. Seven points at the charity stripe for Kelly — the UNC star converted 14 free throws on the afternoon — fueled a quarter-ending 13-2 run to give the Heels their largest lead of the game. A mini 4-0 run for Louisville’s Nyla Harris narrowed the deficit to five, but North Carolina would enjoy a relatively comfortable victory.

Colorado outlasts USC in top-6 PAC-12 clash
No. 6 USC’s standout freshman and Naismith-candidate JuJu Watkins continued her dominant rookie season Sunday against No. 3 Colorado, scoring 12 points in the first quarter alone and looking to make another spectacular play down by three with a drive to the hoop. Instead, her point-guard counterpart Jaylyn Sherrod raced in front of an oncoming Watkins, planting her feet and forcing the Trojan star into her fifth foul on the afternoon. USC could no longer keep up with the stampeding Buffaloes with their star fouled out, falling to Colorado 63-59.

A slow start tempered a raucous home crowd in Boulder — Quay Miller was the only Buffalo to score through the first seven minutes of action — and Watkins brilliance helped USC maintain a two-possession lead over a crescendoing Colorado offense. A Charlotte Whittaker layup finally gave Colorado an advantage late in the second quarter, and the home team led by a basked entering the halftime break. A 8-0 punch out of the locker room, bookended by a pair of McKenzie Forbes triples, thrust the Trojans back in front, and neither team would lead by more than two possessions the entire second half.

Razor thin margins continued into the final minute, as Kayla Padilla nailed her first three of the game and Sherrod split a subsequent pair of free throws, giving USC a chance with the ball down two. But another key Colorado defensive stand forced Forbes into a missed layup, and the Buffs held on late for a massive victory.
