Tennis scoring system

Petra Kvitova compared the atmosphere created by Greek Maria Sakkari's supporters on Rod Laver Arena to "a soccer match" but cut through the noise and battled back from a set down to reach the Australian Open quarter-finals on Sunday.

In an extremely dramatic match in which he almost got the victory, Grigor Dimitrov lost to the American John Isner and thus dropped out of the Masters 1000 series tournament in Paris again in the third round, as in all his previous appearances.
