Andy Murray is Britain's only true Grand Slam champion hope.
But at Flushing Meadows, Murray had to dig deep and find the will to win in his second round match against Adrian Mannarino, being taken to five sets.
Andy lost the first two sets against Mannarino 7-5 and 6-4 and looked certain to be heading for an early exit. But this was when the true champion finally decided to turn up.

Murray, being the two-time Grand Slam winner that he is, just shrugged it off. Knowing that he would have to go the distance to turn his second round match around.
The Scot started the 3 set with true conviction and execution that we have come so used to seeing with Andy, that he found his rhythm and touch, to dictate most rallies throughout the third set, finally crushing the Frenchman 6-1 in that set.

Murray has always had the touch, the skill and the engine for the very top of tennis. But what showed throughout today's performance that we haven't seen for a while since the back injury that hampered most of his 2014 season, was a temperament.
It appears that he has found a way to accept that things in sport just happen, and that its not about focusing on them its about how you react to those moments, that's what makes the great players great. This point was reiterated in the 4 and 5 sets by winning them 6-3 and 6-1 respectively.
Murray had just overcome a hurdle that perhaps he hadn't been expecting, and had just got on with the job in hand, showing his maturity and class.
The Scotsman appears to have been dealt a difficult passage to the final at Flushing Meadows this year by starting off with the unpredictable yet brilliant Nick Kyrigos and now the flamboyant 'lefty' Adrian Mannarino, however this just shows how hard and gruelling men's tennis is these days.
The top 100 are all good players and even if they aren't the best technically, then they all are in terrific shape. Making it harder and harder for these big names to pick them off during the earlier rounds of championships.
And in years to come tennis fans will see more and more of these early-round upsets, but if Murray can show the qualities and character that he did in the final 3 sets of this match, then it won't be Andy Murray having any of these shocks.
