Tiger Woods is subject to discipline by the US PGA Tour for kicking his golf club after a poor shot at the Masters.

Whether he is fined is not likely to be known. The tour doesn’t comment on discipline.

Woods, after a bad miss with a 4-iron into the par-5 15th hole on Friday, hit a poor tee shot with a 9-iron on the par-3 16th. He let the club fall from his hands, then turned in anger and kicked it some 15 yards (metres).

The tantrum received plenty of attention at Augusta National, and it prompted TV analyst Nick Faldo to say that Woods had “lost his game … and lost his mind.”

According to tour policy, players can be disciplined for conduct unbecoming a professional even at tournaments that are co-sponsored or approved by the tour, such as the major championships.

A person close to club operations said no one from the tournament had talked to Woods about his behaviour in the second round. He spoke on condition of anonymity because club matters are private.

Woods was in the second-to-last group on Friday, went straight to the practice range and had a morning tee time on Saturday.

The PGA Tour has been criticised over the years for not disclosing fines.

John Daly told The Associated Press in December 2008 that he had been suspended for sixth months. Even then, the tour would not confirm it. Last year, the tour would not discuss whether Rory Sabbatini was suspended for his treatment of a teenage volunteer at Riviera and for getting into an argument on the golf course with Sean O’Hair.

A person close to Sabbatini later told the AP he had been suspended.

The tour has three categories of penalties – minor (fines not more than $10,000); intermediate (fines between $10,001 and $20,000); major (in excess of $20,000).
