Andy Murray's already tough year has managed to get that bit worse with the news that he has lost his place in the top 10 of the world rankings.
The British no.1 has reached the quarter-finals or better of every Grand Slam in 2014 but the shock US Open final contested between the unlikely pair of Marin Cilic and Kei Nishikori - won by the former - means that both men will leapfrog him.
Murray's fall to 11th represents his lowest position in six-years on the ladder. Since 2008 the 27-year-old has become a two-time major champion and an Olympic Gold medallist and this slide was unexpected.
The former world no.3 is paying the price for trophy-less year to date which started slowly following his back surgery at the end of 2013.
Much of his ranking points were lost in conjunction with his failed Wimbledon defence across June and July.
Murray had become the first British male in over 70 years to triumph in the singles at SW19 in 2013 but his next campaign was ended comprehensively by young-up-and-comer Grigor Dimitrov in the quarter-finals.
The rankings take into account the performances year-on-year at tournaments, and having won Wimbledon in 2013 the only way he could have kept those points was if he repeated the feat.
With that in mind, when Novak Djokovic ended his hopes for a second US Open title this time at the quarter-finals, Murray was unable to improve his own position as Stanislas Wawrinka inflicted defeat at the same stage in the previous New York event.
Now you might think that the rankings are just a statistic and shouldn't affect the Brit too untowardly, however a place at the World Tour Finals in London is hanging in the balance.
Only the top eight will head to the O2 Arena in November for the season-ending show and Murray is well adrift of Tomas Berdych who currently occupies the remaining slot.
The dream hasn't completely gone for the Scottish-born star but he will need to show something special in the remaining tournaments he has signed up for.
Masters 1000 events at Shanghai and Paris provide his last decent hope of booking his place at the London finals but the new world no.11 will need to change a poor run of form against his fellow top stars.
Murray has only beaten one player in the top 10 of the rankings this year, and that was at Flushing Meadows against the enigmatic Jo-Wilfried Tsonga in a round four staright-sets win.
