(AP) - Mariemont High School senior-to-be Will Grimmer has moved a step closer to possibly becoming the second-youngest winner in the 108 years of the Ohio Amateur. He shot a 2-under 69 in Thursday's third round to build a three-stroke lead heading into the final 18 holes.
The 17-year-old, who's committed to play at Ohio State, followed rounds of 72 and 66 to stand at 6-under 207.
Defending champion Andrew Dorn shot a second 69 in a row and shares second place with Tim Crouch, who has put up three 70s, at 3-under 210.
Ohio State's Boo Timko had the day's best round, a 68, and was fifth at even-par through 54 holes at Coldstream Country Club.
Two-time Ohio Am winner Robert Gerwin shot a 76 and is now eight shots back.
