Rory McIlroy has criticised the European Tour for setting up tournament courses too easy.
The four-time major winner finished tied 26th at the Dunhill Links Championship after a closing 67 at the Old Course.
Earlier in the week, McIlroy claimed the sting had been taken out of Carnoustie after gorse bushes were removed to improve access for spectators.
And the world number two aired his frustrations again after his final round at the Old Course.
He said: “I’m sort of honestly sick of coming back over to the European Tour and shooting 15-under par and finishing 30th.
“I don’t think the courses are set up hard enough.
“There are no penalties for bad shots. It’s tough when you come back when it’s like that.
“I don’t feel like good golf is regarded as well as it could be.”
The Northern Irishman, who finished 34th on 13-under at the Scottish Open at The Renaissance Club in July, hopes the European Tour listens to his concerns.
He said: “It happened at the Scottish Open as well. I finished 13-under and 30th again.
“It’s not a good test. If The European Tour want to put forth a really good product, the golf courses and set-ups need to be tougher.”
McIlroy went close to completing his aim of winning the pro-am event with his father Gerry. The McIlroys finished level at the summit on 39-under with Tommy Fleetwood and Ogden Phipps but were pipped by virtue of Fleetwood shooting a 64.
McIlroy added: “We didn’t know it was the lowest pro’s score, which I think is a bit unfair. It should be the lowest team score and we would have won but it’s been a great week.”
