Tyler Gaffalione rode Stormin Charlotte to victory in Gulfstream's ninth race on Tuesday, giving him seven wins on the day.
The Gulfstream card has eleven races.
That ties him with Hall of Fame rider Jerry Bailey for most wins in one day at Gulfstream. Bailey rode seven winners on a 12-race card on March 11, 1995.
Eddie Castro holds the North American record of nine wins on one day at one track. He did that at Calder on a 13-race card on June 4, 2005.
