Former US Open champion Andy Roddick was wished "good luck" for the tournament this morning, despite being retired.
The 33-year-old, who won the Grand Slam at Flushing Meadows in 2003, walked away from the sport three years ago.
However, while taking a stroll in New York, the American was given backing from a passer-by who was unaware that the sportsman was no longer playing.
On Twitter, Roddick wrote: "That awkward moment when you're walking down the street in NYC and someone says 'good luck in the tournament'."
The final Grand Slam of the year got underway on Monday.
