Wimbeldon is currently in the heat.
Polish world setter Iga Swiatek won on Tuesday over Croatian Jana Fett, who is ranked 252nd in the world, with 2-0 in sets.
The victory meant that the world setter extended his winning streak to 36 straight victories.
It is the longest on the WTA Tour since 1997. Of the 36-match winning streak, however, this was the first on grass.
In the next round, Swiatek will face Lesley Pattinama Kerkhove from the Netherlands, ranked 138th in the world.
