To the surprise of probably no one, Caitlin Clark and her Iowa Hawkeyes got a win in their last scheduled home game so The Buckeyes "only" won the league by a single game, 16-2 to 15-3 for the Hawkeyes (and Hoosiers if they win later).
In the interest of full disclosure all three teams did basically the same thing. They each won the home games and lost the road games amongst each other and each of them won the rest of their games with the exception of one random road loss each. The difference in the final standings being that tOSU did not visit Bloomington.
