"He's going to be a Buckeye," said Larimore's father, Jeff. "He is pretty fired up. He just made the decision last night. He's been making a barrage of phone calls to coaches."
Larimore (6-3, 265, 4.8) also had scholarship offers from Illinois, Michigan State, Purdue and Ball State. He is rated as Indiana's No. 6 overall prospect by Scout.com and as the nation's No. 58 defensive tackle prospect overall.
Larimore is also a standout wrestler with a 12-0 record this season. He won three matches at the Rocket Invitational in Park Forest, Ill., pinning all three of his opponents in a combined time of 4:11.
He is ranked No. 3 nationally among high school heavyweights by Amateur Wrestling News.
"He was the most outstanding wrestler in the tournament, which had 16 schools," Jeff Larimore said. "He is 12-0 all season and they are all pins. Only one kid has even taken him to the second period, and he was the No. 2-ranked kid in Indiana. Nobody has scored a point on him yet this year."
Larimore posted a combined 90-5 record as a wrestler the last two years, finishing as the state runner-up each time.
Larimore helped Merrillville post a 22-5 mark the last two years, including 11-3 this year.
"He has exceptional quickness, and explodes off the ball real well," said head coach Jeff Yelton. "He has good brute physical strength having made the finals in the heavyweight division as a sophomore."
OSU coach Jim Tressel made an in-home visit with Larimore earlier this week. His brother, running backs coach Dick Tressel, had been recruiting Larimore.
Larimore holds a 3.4 GPA and scored a 1060 on the "old" SAT.
