Rory McIlroy believes he has what it takes to win at least one major every two years.
Rory McIlroy: Confident.
The Northern Irishman is coming off a poor two days at the Irish Open, where he struggled to control the ball in the blustery conditions and missed the cut.
Nevertheless, the world number one is backing himself to be more than competitive at the upcoming Majors.
"One every two years? I'd like to think so," quipped the 26-year-old on herald.ie.
"My game is in good shape. I'm motivated. There's no reason why I can't compete and give myself chances in a lot more Majors.
"I've got three more majors this year. I think two of those, I have good chances on. I know the courses well. I've played well on them before."
However, McIlroy will have a tough task as the remaining three Majors of 2015 are on links courses, where the elements are often a factor.
Chambers Bay, 2015's US Open host, was recently billed as a challenging course by Tiger Woods, while the wind at St Andrews has played its part before.
At the 2010 Open Championship, the howling gales at the home of golf saw McIlroy slump to a nine over par 80.
The final Major of the year tees off at Whistling Straights on the shores of Lake Michigan, which derives its name from the consistent wind.
