Kenin, meanwhile, has dropped a set in four of her six matches but her deciding sets in those battles read 6-3, 6-2, 6-1, 6-0. She is one tougher little nut to crack, having saved 69 per cent of break points (40/58) compared with Swiatek’s 63 per cent (15/24).
Kenin has spent 10 hours and 34 minutes on court in singles, plus a further six hours and 18 minutes just to reach the doubles quarter-finals with Bethanie Mattek-Sands. Swiatek, on the other hand, has spent seven hours doing battle in singles, and four hours, 33 minutes in doubles alongside Nicole Melichar, and counting. The pair are still alive in the women’s doubles semi-finals.
Both women are equally dangerous off both wings. Kenin has hit 194 winners, including 82 on the forehand and 99 on the backhand, while Swiatek has 150, including 60 each off both sides.
