Preamble
Hello. It’s been a terrific, wildly unpredictable US Open so far and today’s quarter-final line-up promises more of the same. The late session sees Iga Swiatek take on Jessica Pegula, and Carlos Alcaraz square up to Jannik Sinner – but first, another pair of match-ups that look impossible to call.
Frances Tiafoe, conqueror of Rafa Nadal, is bidding to maintain his new-found momentum against Andrey Rublev, who ended Cam Norrie’s hopes with ominous ease in the last round. Both players have the talent to go all the way to the final; neither has ever reached the semi-final at a grand slam.
Before that, it’s Karolina Pliskova v Aryna Sabalenka – two mainstays at the very top of the women’s game, somehow still without a grand slam title between them. Both players fought from a set down in the fourth round; their head-to-head record stands at 2-2. There’s no point trying to predict the outcome, but it should be fun finding out.
