It marks just the second time in program history that the Buckeyes started Big Ten play with a 3-0 record.
"We always try to take things one game at a time," head coach Lori Walker said. "We're just trying to stay focused and play 90 minutes at a time and the results will follow."
The Buckeyes controlled much of the first half, outshooting the Hawkeyes 7-0, putting five of those shots on frame. Ohio State also held a 3-0 advantage in corner kicks as the teams headed into halftime scoreless.
However, it would not take long for the Buckeyes to get on the board in the second half. Less than three minutes into the half, Maxwell scored her team-leading fifth goal of the season from six yards out off assists from Lauren Steuer and Danica Wu. The goal also marked Maxwell's team-leading third game-winner of the season and third in as many games.
Just over 10 minutes later, Maxwell scored her sixth of the 2010 campaign, extending the Ohio State lead to 2-0 on her fifth goal in her last four games when she beat Iowa goalkeeper Emily Moran far post off a pass from Steuer. The goal marked Maxwell's team-leading third game-winner of the season and third game-winner in as many games. The two-goal game came after Maxwell scored her first career hat trick in her first match against Iowa as a freshman two years ago.
"Paige has been putting in a lot of time working on her finishing," Walker added. "We have a great element of competition with our forward line and it's all performance-based. Paige has really been stepping up and contributing each game and finding the back of the net."
The Hawkeyes cut the Ohio State lead in half in the 73rd minute when Morgan Showalter scored her third goal of the season off a free kick from Mandy Heimann, but the Buckeyes continued to put the pressure on, recording three shots in the ensuing five minutes. In the 81st minute, Tiffany Cameron gave the Buckeyes some insurance when she beat Moran for a 3-1 Ohio State lead off an assist from Karin Sendel.
Less than two minutes later, Wu almost pushed the lead to 4-1 but her shot deflected harmlessly off the post.
For the game, Ohio State held an 18-7 advantage in shots including 10-2 on goal. The Buckeyes also held an 8-1 advantage in corner kicks. It is the 11th-consecutive game Ohio State held its opponent to a goal or less.
The Buckeyes (9-2-1, 3-0-0 Big Ten) travel to Evanston, Ill., to take on Northwestern at 3:30 p.m. Sunday.
