Open Extended ReactionsFanDuel said it has banned a bettor who posted a video of himself heckling Olympic gold medalist Gabby Thomas at a recent track event and claimed "it made my parlay win." Thomas posted on X that the unnamed man "followed me around the track as I took pictures and signed autographs for fans (mostly children) shouting personal insults" last weekend at a Grand Slam Track event in Philadelphia. Grand Slam Track said in a statement that it is conducting a "full investigation into the reprehensible behavior captured on video." "We are working to identify the individual involved and will take appropriate action as necessary," Grand Slam Track said. Gabby Thomas said a man "followed me around the track" and insulted her at a recent event.
