This one was WAYYY closer than you'd think! Zac Rice hit the most HRs in GP, but his longest was only tracked at 358. Daniels? 392. Heath (8/7 v ALP) and O'Neal (7/17 v ATL) each hit 403. O'Neal: 403.35 feet Heath: 403.16 feet By about 2 inches, the right answer is Conner O'Neal! Fun fact, it's also the only Grand Slam hit in Hoots history too! #HootyHoo #GoHoots #Homeruns #columbusGA #phenixcityAL #GoldenPark
