Men's 800 final in 92 Olympic Trials New Orleans. Johnny Gray went coast to coast on a US soil record but the kick was from Mark Everett & Jose Parilla running in 7th & 8th with 120 meters to go to gain the final team berths. Poor George Kersh ran 1:44.00 to finish 4th the second time in a row.
Fermin Cacho ran a pretty fast last 400 in a slow 1500 in Barcelona Olympics.
