There could be a horse racing Triple Crown winner this year. Officials announced on Saturday that Kentucky Derby winner Mystik Dan will run in The Preakness Stakes at Pimlico Race Course and is on his way to Baltimore. There have been only two Triple Crown winners since Seattle Slew and Affirmed won back-to-back in 1977 and 1978. American Pharoah broke a 37-year drought by winning the Triple Crown in 2015 and Justify won it in 2018. The 149th running of The Preakness is set for this Saturday the 18th.
