Left-hander Connor Curlis (5-1) helped the Buckeyes (20-9, 3-2 Big Ten) get off to a strong start, scattering six hits with a season-high eight strikeouts and two walks in 6 2/3 innings on a gusty, 34-degree afternoon.
Seth Kinker pitched out of a couple of jams to earn his seventh save. He struck out four and gave up two hits and hit a batter in 2 1/3 innings.
Tyler Cowles and Jacob Barnwell had RBI singles in the fifth to wipe out the Hawkeyes' one-run lead.
A seven-run first inning by Iowa (18-11, 4-3) was aided by two Ohio State errors in the second game.
Right-hander Ryan Feltner (3-2) lasted four innings and gave up seven runs (two earned), six hits with five strikeouts and three walks
