The last time Andy Murray arrived at the US Open as a freshly anointed Olympic champion he walked away with his maiden Grand Slam title. Four years down the line, the super Scot looks in even finer shape to pull off this double again.
Safely into the last eight after pummelling 22nd-seed Gregor Dimitrov 6-1, 6-2, 6-2, the Rio Gold Medallist is now the 13/10 second favourite to lift the trophy at Flushing Meadows with bwin.com.
There have seldom been more encouraging omens for the world number two heading into the business end of a Slam either.
The reunion with coach Ivan Lendl back in June, shortly before Murray would claim his second Wimbledon crown, has noticeably bestowed Murray with a more ruthless edge, personified by his serving in the Big Apple.
Against a stunned Dimitrov, who has ended Murray’s Grand Slam interests before now at Wimbledon 2014, the Brit recorded his fastest ever competitive serve of 141 mph.
Nine aces flew past the Bulgarian’s outstretched racket and for someone whose strongest suit is recognised to be returning, this awesome display of power serving is an ominous sign for those still standing in the Dunblane native’s way across the pond.
After securing his quarter-final spot the Briton said: “I got a lot of free points with my serve tonight. The conditions do a lot for you to serve quick. The balls are fast. I wanted to use that to my advantage as the tournament goes on.”
Kei Nishikori is next in Murray’s sights and as the Japanese player’s 2014 US Open final appearance shows, he is a dangerous opponent.
However, a tot up of the their head-to-head record suggests it’s advantage Murray before the coin toss.
The British number one is 7-1 up in previous clashes. This includes a 6-1, 6-4 victory over Nishikori in the semi-finals of the Olympics in Brazil and a five-set Davis Cup epic back in March, when Murray let a two-set lead slip before powering through 6-3 in the decider.
There is of course the spectre of his nemesis Novak Djokovic lurking on the other side of the draw, looking far more focused than he was when suffering his shock Wimbledon exit off the back of finally securing the career Slam at the French Open.
Murray has defeated the Serb this season to claim the Rome Masters, but is winless in the past five Slam tussles.
Then again, since his last Djokovic defeat in the final of the French Open back in May, the Brit has only been defeated once in 27 matches on grass or hard courts, scooping three titles.
