Shelton

In it, Maron shares his recollection of Sharon Stone encouraging him to connect to his loving memories of his late partner, Lynn Shelton.

Having said he "didn't enjoy" his battling win over Damir Dzumhur in the third round, Alcaraz was far closer to his best on Sunday and had to be against the big-hitting Shelton.

The first set headed to a tie-break after only one unconverted break point for the favourite, but it was Shelton who initially gained the upper hand.

Shelton earned six break points in the opening game but was denied each time by Alcaraz, who turned it on late in the set to claim the crucial break.

But Shelton was far from done and after the duo exchanged breaks early in the third set, the 22-year-old from Atlanta saved a break point for a big hold at 4-4.
