Rory McIlroy had been waiting seven years, 11 months, eight days for this opportunity, ever since he won his fourth major at Valhalla in 2014. And in the end all that time turned on one moment, at 6.30pm on the 17th green of the Old Course at St Andrews.
Way ahead of him, up the 18th fairway, Cameron Smith was standing over a two-foot putt that would take him to 20 under for the championship. McIlroy, two shots back from that, knew he needed to finish with back-to-back birdies to match him, and take the 150th Open into a playoff.
