The most obvious heir to the world number one spot and surely a future Grand Slam champion, Simona Halep's rise to glory has often seemed inevitable.
She has come agonisingly close to both, falling a win short of securing top spot at the French Open (where she lost in the final for the second time), Wimbledon and, most recently, in Cincinnati.
Arriving just five points behind current number one Karolina Pliskova, Halep has never been closer to glory, but such pressure rarely extracts her best, as fully apparent in a 6-1 6-0 battering by Garbine Muguruza in Ohio.
The Romanian may lack the natural power game to be considered a force on hardcourts, but her win percentage is actually higher at Flushing Meadows than at any other Grand Slam.
Semi-final and quarter-final runs in the last two seasons have been key in pushing that figure up, but the 2015 final-four 6-1 6-3 defeat to Flavia Pennetta must be considered one of her most disappointing performances.
