And before Wozniacki, Rory had a live-in girlfriend with whom he watched Wozniacki playing tennis on the telly and decided he “fancied” the woman on the screen more than the one sitting next to him. What you can say? He’s a cad. But that does seem to be par for the course among many of his colleagues at the elite level of pro golf.
I'm sure there is a percentage that fit that profile, as in any career group. But many are good family men too. And yes, they work hard. It takes a helluva commitment - and talent - to make the pro tour, and just as much to stay there.
