Having fought back from two sets to one down to defeat Frances Tiafoe in the previous round, Alcaraz seemed to be enjoying a much easier time of it as he stormed the opening two sets, only for Humbert to produce some sublime tennis thereafter.

The Frenchman too would have felt aggrieved to lose the second set, in fact, as he squandered four break points on Alcaraz’s serve in the fifth game. And then, having only coughed up four points all set on his own serve, Humbert was suddenly broken out of nowhere to lose the set 6-4.

He was not to be deterred, though, as he proceeded to break the Alcaraz serve on four straight occasions over the course of a dominant third set and early into the fourth.

The defending champion appeared to have no answer for Humbert’s immaculate return game, the 16th seed hitting thumping winners with regularity and mixing in the odd heavy ball to the back of the baseline to do for the flat-footed Span

That said, Alcaraz himself twice broke Humbert to start the fourth set, but things were back on serve by the end of the sixth game as the determined Humbert continued to dig his heels into the Centre Court grass.
