World number one Rory McIlroy suggested he was "probably in need of a rest" after missing the cut by ballooning to a six-over-par 78 in the second round of the BMW PGA Championship at Wentworth.

The defending champion frittered away stroke after stroke at the European Tour's flagship event and his five over total of 149 meant he missed the cut by a considerable margin.

McIlroy is in the middle of an untypically busy schedule of five tournaments in a row that will end with the Irish Open event he hosts at Royal County Down next week.

The 26-year-old Northern Irishman cruised to a seven-shot win at the Wells Fargo Championship in North Carolina on Sunday but he told reporters on Friday that his trans-Atlantic exertions had finally caught up with him.

"I'm a little disapppointed I'm not going to be here for the weekend," said McIlroy, who also won the WGC-Cadillac Match Play in California at the start of the month. "I'd still rather be here but it's not all bad getting to go home for the weekend.

"If there was any weekend to miss, coming off the back of three good weeks in the United States, I'm probably in need of a little bit of a rest."
