Under the lights Elina Svitolina waits, clad in a purple dress and yellow shoes and wearing concentration. The match is 21 points and 12 minutes old and the first break point versus Kiki Bertens has come.
This is not just about a serve. This is about breaking everything, a rival's spirit, their heart, their game, their rhythm. Politely, of course. But it's only the fourth game and that's never make or break.
