Sportsbook platform FanDuel banned a bettor on Wednesday who filmed himself heckling Gabby Thomas during a race at Grand Slam Track’s Philadelphia meet over the weekend.
Thomas competed in the 100m in the women’s short sprints race group on Sunday and finished fourth behind the winner, Melissa Jefferson-Wooden.
In a social media post, the bettor wrote that he “made Gabby lose by heckling her. And it made my parlay win.”
A screenshot of a two parlays showed the he wagered on Jefferson-Wooden to take the 100m and he won $2,000 on the bets. Both transactions showed Jefferson-Wooden as a favorite over Thomas in the women’s 100m.
According to Thomas’ own posts on social media, she described the man’s actions in the moments following the race while she interacted with fans as the meet was nearing the end of it second day.
“This grown man followed me around the track as I took pictures and signed autographs for fans (mostly children) shouting personal insults — anybody who enables him online is gross,” her post read.
The man, who is known as “mr100kaday” on social media platform X, made several posts about Thomas and Grand Slam Track during both days of the meet on Saturday and Sunday and his profile description notes that he is a “track and field bully.”
In another video, the man is heard yelling at Thomas as her race group settled into the starting blocks.
Following the race, in a separate video, the man speaks to Thomas again as she asks, “What are you doing here?”
“FanDuel condemns in the strongest terms abusive behavior directed towards athletes,” a FanDuel spokesperson said in a statement. “Threatening or harassing athletes is unacceptable and has no place in sports. This customer is no longer able to wager with FanDuel.”
As word of the incident made the rounds in track and field circles late Sunday, Grand Slam Track officials launched their own inquiry into what occurred during the race.
“We are working to identify the individual involved and will take appropriate action as necessary,” league founder Michael Johnson said in a statement. “We will implement additional safeguards to help prevent incidents like this in the future. Let us be clear, despicable behavior like this will not be tolerated.”
In a post on the “mr100kaday” account on Wednesday, the man claimed that he did not have a FanDuel account and was assists other bettors to place wagers.
“I read in the media that Fanduel banned me. This is false,” the post read. “I dont have a personal Fanduel account. Others pay me consulting fees for thier bets and i get percentage of profits. I had almost 100 clients who placed that same bet and won. So did they ban?”
In another post, from Tuesday, he calls Thomas a “compulsive liar,” while also singling out sprinters Tia Jones and Alaysha Johnson — both who have participated in the league’s meets.
