Italy’s Francesco Molinari leads the BMW PGA Championship by two shots after a seven-under-par 65 in the first round at Wentworth.

Defending champion Rory McIlroy, who said he is suffering from mental tiredness, is six shots behind.

“Physically I am all right but mentally I could feel myself getting a little angry out there,” said the 26-year-old.

Sweden’s Robert Karlsson is two shots off the lead with Britons Chris Wood and Marc Warren a further shot back.

World number one McIlroy, who won his 11th PGA Tour title in the United States at the Wells Fargo Championship last week, hit three bogeys in a round of 71 despite perfect conditions.

McIlroy admitted to feeling angry in his opening round and his challenge going forward will be to re-harness the inner calm that has been the hallmark of his recent success. The world number one is still firmly in the mix but leader Molinari is capable of capitalising on his fine start. The inconsistent greens were disappointing for an event of this stature. Luke Donald, though, can feel very pleased with his bounce back after recovering from two over par to post a two under 70. The two-time former champion is desperate for a high finish. After slipping to 60th in the world rankings he is in danger of missing the next two majors, the US Open and Open at St Andrews.

“Acceptance of bad shots is the thing I have been doing so well and I feel like my patience was wearing a bit thin today,” said the Northern Irishman.

“I just need to stay in control of my emotions because I feel like that’s one of the things – if I’m a little tired or a little fatigued mentally, I’ll start to be hard on myself and start to get down on myself.”

Molinari, whose brother Edoardo retired with a wrist injury during the first round, hit seven birdies including two on the final two holes.

“I think I missed one green on the third and chipped up to two feet, so it was as stress-free as it could be round here,” said the 32-year-old.

“I love this place and it’s good to be back. It rewards accuracy, which suits my game.”

Wood, who dropped just one shot – on the par-five 17th, has played just six events this season after five months out with a broken bone in his wrist.

“It was a nightmare because I fell out of the top 60 on the Race to Dubai and plummeted down the world rankings,” said the 28-year-old.

Ireland’s Padraig Harrington pulled out with a shoulder injury after playing just two holes.
