Rory Mcllroy has finally sacked his caddy JP Fitzgerald after six years of employment.

As a result of his lack of form and coming up short once again at this year's British Open, the Irishman has decided that enough is enough and something has to change. 

He has therefore turned to his long-term friend Harry Diamond, according to the Sun, who used to caddy for Mcllroy when he was a junior golfer.

It is understood that Diamond will be Mcllroy's caddy for the next two events to see how the pair work together. 

Many have called for Mcllroy to part company with Fitzgerald since he remained utterly mute following the former world number one's outburst of rage after a poor tee shot on the 10th at Augusta in 2011. 

However, Mcllroy remained loyal to Fitzgerald and responded to his critic Jay Townsend by tweeting: "Shut up, you're just a failed golfer." 

It has been a similar story ever since, with McIlroy refusing to listen to calls for him to hire a more pro-active caddie, until now that is. 

Diamond last carried his friend’s bag when he played in the 2005 Irish Open as a 16-year-old amateur prodigy.

He will be pressed into duty for this week’s World Golf Championship event, the Bridgestone Invitational in Akron, and could also be on the bag for next week’s USPGA Championship.

Although, despite being a great friend of Mcllroy, it is understood that Diamond is not a permanent replacement but rather a stop filler until a more suitable and professional caddie is found. 

According to the Mirror, McIlroy is eyeing caddies from his Ryder Cup teammates.

On the shortlist is Lee Westwood's Billy Foster, and Martin Kaymer's Craig Connelly.

The next two tournaments, however, will see whether it was in fact the caddie that was responsible for Mcllory's dip in form, or whether other facts have had an affect on the Irishman's performances. 

Although one thing is for sure - Mcllroy will want this issue resolved fairly quickly before the final Major of the year in America.
