Junior guard Caitlin Clark led the Hawkeyes with 28 points, 15 assists and 10 rebounds for the eighth triple-double of her college career. Clark, who celebrated her 21st birthday on Sunday, has the third-most triple-doubles in Division I history, trailing Oregon's Sabrina Ionescu (26 from 2017 to 2020) and Lamar's Chastadie Barrs (nine from 2016 to 2019).
Clark's four triple-doubles with 25 points or more are the most in Division I history, according to ESPN Stats & Information data. She is also the only Division I player in the past 20 seasons to have four consecutive games of at least 20 points and 10 assists.
"I think it's meaningful, and when I'm able to do that, it puts my team in a really good position to win," Clark said of getting a triple-double. "That's just kind of what I pride myself in, being able to do a lot of different things on the basketball court for my team. I think it makes me really versatile, hard to guard."
Ohio State is the highest-ranked team Iowa has defeated in coach Lisa Bluder's tenure, which started in the 2000-01 season. The last time Iowa beat a top-two team was under then-coach C. Vivian Stringer on March 4, 1994, versus then-No. 2 Penn State.
The Hawkeyes (16-4) were without starting forward McKenna Warnock, who is day-to-day with a rib cage injury. But with Clark, Monika Czinano (22 points on 11-of-13 shooting), Kate Martin (13 points, 11 rebounds) and Hannah Stuelke (eight points, 13 rebounds), they still had enough to stop the Buckeyes (19-1), leaving just No. 1 South Carolina and No. 4 LSU as the lone Division I women's unbeatens.
Ohio State was just 4-of-25 from 3-point range on Monday.
"We had some really great performances," Bluder said. "Gabbie Marshall did a great job on Taylor [Mikesell]. Great assists by our team -- 24 on 31 baskets. That's really fun basketball. Caitlin has a triple-double; what can that girl not do? They all did a great job. This is a big win."
Iowa, Ohio State and Indiana, which defeated Michigan 92-83 on Monday night, are tied atop the Big Ten at 8-1. Indiana, which at 18-1 is off to the best start in program history, will host Ohio State on Thursday.
"This is my 23rd year in the league, and it's the toughest I've seen it," Bluder said of the Big Ten competition.
