Who is Rory McIlroy's new caddie Harry Diamond?
Former Irish amateur international Harry Diamond will be on Rory McIlroy's bag, it's believed, for the fourth major of the year.
It has now been confirmed that Rory's life-long pal will take over caddying duties for this weekend's BWGC Bridgestone Invitational and the following USPGA Championship. But just what do we know about him?
1. Diamond could have been a professional star in his own right
The Belvoir Park golfer won the 2012 West of Ireland Championship to earn himself a spot in that year's Irish Open, even if he did miss the cut after shooting rounds of 77 and 74 at Royal Portrush's Dunluce Course.
Diamond also reached the final of the 2011 North of Ireland Championship on the same track and took Patrick McCrudden to a tie-hole round his own course. That's just in case you thought his West win was a one-off. His north coast performance earned him a senior debut for Ireland, who he had also represented at Boys and Youth levels.
In 2014, his handicap was +2.5. In short, he's fairly handy.
2. It's not the first time he has caddied for McIlroy
Diamond was on bag duty during a practice round at the 2005 Irish Open, when the then 16 year-old McIlroy was invited to play in the tournament for the first time. He was again called up for the Par Three tournament at the 2011 Masters and also for the 2014 Alfred Dunhill Links Championship.
3. Diamond and McIlroy are childhood friends
The pair both grew up in Holywood and have long been close friends. Diamond was even on best man duty for Rory's wedding to Erica Stoll earlier this year. Certainly, there are few men McIlroy would feel more comfortable having around the course this weekend than his long-time friend.
4. He's not just a talented golfer
Harry Diamond owns a string of bars and it was his business activities that played a part in his decision not to follow McIlroy into the world of professional golf. His performances at the North and West of Ireland certainly proved his credentials on the course.
5. A two-week trial could yield a permanent post
Diamond is tipped amongst the favourites to land the role on a permanent basis - although much could depend on his, and his boss', performance during the next two tournaments. Behind Danny Willett's former caddie Jonathan Smart, the 8/11 favourite, Diamond is at 5/2 with Paddy Power to take over bag duties full-time. All we know for now, is that we'll see plenty of him on our TV screens over the next two weekends.
