Negreanu called Sexton a competitor, a friend and a remarkable human being.
Poker player Linda Johnson said that Sexton was battling prostate cancer that had recently spread to other organs. He had been in hospice care for about a month, she said.
Sexton spoke to the Dayton Daily News in 2004 about learning poker while growing up in the Dayton area. He said he often lost his paper route money to schoolmate Danny Robinson playing cards. Robinson would later become one of the best seven-card stud players in the country.
“For my route with The (Dayton) Journal Herald, I would collect every Friday,” said Sexton. “When I got home, Danny — who was two years ahead of me in school — would be shuffling cards on my stoop waiting for me. He kept me broke.”
As a player, he won nearly $7 million since his debut in the 1980s, according to CNN.
