There’s an invisible line that a good team must cross to become a national or even conference contender.
Iowa climbed over that mental barrier on Sunday in Columbus, Ohio.
Roy Devin Marble scored 22 points, Aaron White added 19, and the 20th-ranked Hawkeyes ended the game on a 22-9 run to hand No. 3 Ohio State its second loss of the week, 84-74.
It was Iowa’s first win over a top 5 team since an 83-65 victory at No. 2 Missouri on Dec. 15, 2001.
Melsahn Besabe had 11 points and 10 rebounds, Mike Gesell added 11 points, and Jarrod Uthoff had 10 off the bench for the Hawkeyes (14-3, 3-1 Big Ten), who ended a string of eight straight losses to the Buckeyes. Full story for BostonGlobe.com subscribers.
