Two Daily Racing Form clockers, however, had timed Secretariat's Preakness in 1: 53 ​ ⁄, which would be a new stakes record . A hearing was held over the time discrepancy, where a video replay showed Secretariat reached the wire faster than Canonero II, the then - current record holder, but instead of giving Secretariat the record, the Maryland Jockey Club decided to split the difference and make its official time that of Pimlico's clocker, who had timed the race in 1: 54 ​ ⁄ . The matter was finally resolved in June 2012, when a meeting of the Maryland Racing Commission unanimously ruled to change Secretariat's final time to 1: 53 based on testimony and analysis of the race replays . Consequently, Secretariat holds the current official record for all three Triple Crown races . </P> <P> Margin of Victory: </P>
