… Michelsen, unfazed, has just broken Tsitsipas in the opening game of the fourth set. The Greek is rattled, mouthing off at his box and thumping his racket against his kitbag. The American is playing smart tennis, keeping the ball in play, executing high percentage points and allowing his opponent to combust.

Stefanos Tsitsipas (11) is on the comeback trail! The Greek, with John Cain Arena well behind him, has won the third set to reduce the deficit on Alex Michelsen. The American won only two of ten points behind his second serve in the third set, allowing Tsitsipas the chance to dictate terms.

After grinding through the opening set, Coco Gauff is now a break up in the second and in control 3-1 against Sofia Kenin. Kenin has won just 46% of points behind her first serve and has 20 unforced errors to just nine winners. This undermines how much of the match has been played on Kenin’s terms, but so often a crucial forcing shot has landed fractionally long or wide, especially crosscourt forehands.
