LAS VEGAS ā€” "Jeopardy!" champion and professional sports gambler James Holzhauer finished out of money in his World Series of Poker debut on Monday, a tournament official said.

Holzhauer finished in 454th place among more than 1,800 entrants in a No-Limit Holdā€™em event, spokesman Seth Palansky said. Buy-in was $1,500 and Holzhauer didnā€™t reach the top 281 finishers who will win shares of some $2.5 million in prize money.

Holzhauer moved to his second poker event of the day, to play with Poker Hall of Famer Mike Sexton in a $1,000 buy-in Tag-Team No-Limit Holdā€™em tournament. Sexton began play for both of them.

Holzhauer told tournament officials he plans to donate half of any winnings to a Las Vegas nonprofit for homeless, displaced and disadvantaged high school students called Project 150.

Holzhauer played online poker semi-professionally in the early 2000s, but makes a living now with sports betting.

He became a celebrity winning 32 consecutive ā€œJeopardy!ā€ games and raking in more than $2.4 million before he lost in early June. He ended his run a little more than $58,000 shy of the overall earnings record set by Ken Jennings, who won 74 games in 2004.

Holzhauer left with the 16 highest one-day scores in the showā€™s history.

He has taken part in several events in Las Vegas in recent weeks, and donated $10,000 in May to Project 150. He and his wife Melissa also contributed $10,000 to a different nonprofit school dropout prevention program called Communities In Schools of Nevada.

Holzhauer made a recent donation of about $1,100 in ā€œJeopardy!ā€ host Alex Trebekā€™s name to a pancreatic cancer walk in Holzhauerā€™s hometown, Naperville, Illinois.

Trebek, 78, announced earlier this year that he was being treated for advanced pancreatic cancer. He said last month that doctors told him heā€™s in ā€œnear remission.ā€
