The former world #1 and current US Open champion lost a dramatic match to Ekaterina Makarova, making yet another early round exit. After losing the first set to the Washington champion, Kerber rallied back to force a decider that climaxed in a third-set tie break.
Played in very hot & humid conditions, the tie-break saw Makarova struggle with cramps, at one point going down on court in pain.
