Two-time major winner John Daly has claimed he is retiring from golf, according to the Golf Channel.
The US cable television channel has been following the 1995 Open and 1991 US PGA champion for a reality show that begins in March called Being John Daly.
And after missing the cut at the Farmers Insurance Open in San Diego he told a camera crew from the show: "I'm done."
Daly, playing on a sponsor's exemption, carded rounds of 79 and 71 at Torrey Pines, the scene of the last of his five PGA Tour victories at the 2004 Buick Invitational. Asked to explain what he meant by "done", he said: "With golf.
"I can't compete. I can't play like I use to. I can't keep taking spots from guys out here playing this bad. It's not worth it. I'm tired of embarrassing myself in front of (my fans). I can't do it any more."
Daly (43) had also missed the cut at his first event of the year, the Sony Open in Hawaii, two weeks ago as he bid to rebuild his career, having served a suspension from the PGA Tour for the first half of 2009.
He instead played on the European Tour, competing in 10 events, tying for second at the Italian Open and 27th at the Open at Turnberry. On returning to the USA, he played six events, missing two cuts and withdrawing from another.
Meanwhile, world number two Phil Mickelson has defended his use of a 20-year-old wedge in the wake of accusations by fellow professional Scott McCarron he is cheating by using it.
Mickelson has opened his PGA Tour campaign for 2010 with a Ping i2 wedge in his bag at the Farmers Insurance Open, where he was seven under par, four shots off the second round lead of fellow American DA Points and Japan's Ryuji Imada, exploiting a loophole in equipment regulations introduced on January 1.
While the club features the grooves banned by the US, a lawsuit in the early 1990s led to Ping wedges manufactured before 1990 being allowed to be put in play and several tour players have opted to use them, Mickelson the most high-profile.
"It's cheating, and I'm appalled Phil has put it in play," said McCarron.
McCarron is a member of the PGA Tour Players' Committee and Mickelson agreed in principle that he was exploiting a loophole. Asked to respond directly to McCarron's accusations of cheating, Mickelson replied: "I think rather than answer that directly, I think what he's saying is the rule is a terrible rule, and I agree.
"I don't agree with the way he (McCarron) carried on about it, but that's his choice. All my clubs are approved for play."
