He resurfaced in 2015, when he qualified to play in the Frys.com Open. He played in about 20 tournaments in 2015 and 2016.
His third leukemia diagnosis came last summer. His wife had documented his treatment in recent months, writing about his pride at taking his first steps in a hospital hallway after weeks without walking, the smile on his face after a visit from his daughter, and a carefully arranged visit outside. She also noted the complications that arose as his health declined.
“He has given everything that he’s got to give,” she wrote on July 31, announcing Lyle’s decision to end active treatment, “and his poor body cannot take any more.”
The golf community had been monitoring his condition and offering support. Last week, at the World Golf Championships in Akron, Ohio, players wore yellow ribbons on their caps and visors in Lyle’s honor.
“I could tell from the start that this third cancer battle was going to be tough,” Allenby wrote in a tribute published last week on PlayersVoice, an Australian sports website. “There was a confidence in him the first two times, an ‘I’m going to beat this’ attitude. It was different this time. We were at the Australian Open in November and he said to me, ‘I’m really scared. I don’t think this is going to be a great outcome.’ ”
Besides his wife, Lyle’s survivors include his two daughters, Lusi, 6, and Jemma, 2. In her statement, Ms. Lyle said her husband had spent his final days in Torquay, the seaside town near Melbourne where he had lived.
She added that Lyle had asked her to pass along this message: “My time was short, but if I’ve helped people think and act on behalf of those families who suffer through cancer, hopefully it wasn’t wasted.”
