Grand Slam Track Investigates Man Heckling Gabby Thomas During Race to Win Bet

Grand Slam Track is investigating a fan who said he heckled sprinter Gabby Thomas during an event in Philadelphia this past weekend so that he could win his bet, per Margaret Fleming of Front Office Sports.

The user reportedly goes by "Mr. 100k A Day" on multiple social media platforms and responded to Thomas' recap post from the meet by writing: "I made Gabby lose by heckling her. And it made my parlay win."

The social media post included a video where the user said "You’re going down, Gabby" three times and called her a "choke artist" while standing directly above the runners as they lined up for the race. He also posted screenshots of his winnings from two-leg and four-leg parlays on FanDuel, indicating that he wagered a total of $1,200 and won more than $2,500 after Melissa Jefferson-Wooden was victorious in the race.

Thomas, a three-time gold medalist in the Paris Olympics last summer, posted a direct response to the user's post, saying he followed her around and heckled her with personal insults:

"Grand Slam Track is conducting a full investigation into the reprehensible behavior captured on video," the league said in a statement, per Fleming. "We are working to identify the individual involved and will take appropriate action as necessary. 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."

The Philadelphia Slam at Franklin Field marked Grand Slam Track's third meet of its inaugural season. League founder Michael Johnson previously said that the thought process in picking the smaller stadium was to create "a much better, intimate experience for fans."

This incident could push Grand Slam Track to follow the lead of other leagues like the WNBA and the NCAA, which made commitments to policing harmful fan behavior toward athletes.
