I found the following...
Sean Carney - Darby, 6th in the 2 mile at 9:08.11
Dylan Christian - Granville, 7th in the 800M at 1:52.97
Conner McClure - Green, 4th in the PV at 4.88 (~16'0")
Jack DeFrancisco - Davidson, 10th in the PV 4.63(~15-2.5)
Jimmy Rhoades - Liberty Union, 12th in the PV 4.48(~14' 8.5")
Malachi Collier - Maple Hts?, 3rd in the LJ at 7.26(~23'9.75")
Alex Smith - Darby, 13th in the LJ at 6.89(~22' 7.5")
Owen Karas - St. Charles, 22nd in the Mile at 4:17.22
Gabe Hickman - Turpin, 11th in the SP at 17.67 (~58')
Kenna Stimmel - Margaretta?, 3rd in the PV at 4;17 (~13' 8.25)
Brynn Rychlik - Marysville, 19th in the PV at 3.70 (12'1.5")
Annika Kinley - Lakota West, 3rd in HJ at 1.74 (5' 8.5")
Certainly not an exhaustive list...
In any event, much less Ohio representation than for previous "outdoor nationals". I suppose it's just too far... too far out in time, too far away.
