Karolina Pliskova retires after three points at US Open with ankle injury
Jasmine Paolini, the No. 5 seed, didn't even have time to break a sweat inside Louis Armstrong Stadium.
This is the first tour-level matchup between Pliskova and Tomova.
For the first time since Dubai in February, the Czech has won back-to-back matches.
The Czech increased her win streak to nine matches following her 7-6 (6), 7-6 (5) victory on Thursday.
