Lamont Jones, the MAAC player of the year, came into the game averaging 23 points. He was held to nine on 3-of-14 shooting.
The Gaels held a brief 6-5 edge following a layup from Jones, but the Buckeyes scored the ensuing 15 points and were in front the rest of the night. Thompson capped the burst with an alley-oop jam off a feed from Shannon Scott with 12:38 left in the half.
"An alley-oop is a great team play," Thompson said. "It shows two guys on the same page offensively. Shannon did such a great job getting into the teeth of the defense, having the defense collapse, and just letting me do the easy part and finishing it. It really gives our team a boost offensively and defensively and definitely gives the other team something to think about."
Ohio State increased its lead to as many as 19 in the half, but the Gaels trimmed it to 37-33 following Tre Bowman's layup with 1:36 left. Ohio State countered with a dunk from Thompson, and the Buckeyes headed to the half up 43-33 following a pair of Thompson free throws in the closing seconds.
"It's like the first game of the season all over again," Armand said. "Everybody's a little excited, trying to do a little bit too much. We just had to get our heads together. We just kept telling each other to chip away at the lead. Fouls didn't go our way, and we are back down 10 at halftime."
The Buckeyes made half of their 32 shots in the opening 20 minutes, while the Gales struggled at 36.4 percent.
Thompson had another jam two minutes into the second half to cap a period- opening 9-0 burst. The double-digit margin remained the rest of the game and Ohio State led by as many as 30 down the stretch.
