he Iga Swiatek winning streak just kept growing in Stuttgart on Friday, as she held off a stern challenge from reigning US Open champion Emma Raducanu in the quarterfinals of the WTA 500 clay-court event, 6-4, 6-4, for her 21st win in a row.
The 20-year-old Polish trailblazer’s winning streak began with three straight WTA 1000 title runs in Doha (5-0), Indian Wells (6-0) and Miami (6-0), and has continued over the last week at Billie Jean King Cup (2-0) and Stuttgart (2-0 so far).
She’s also won her last 28 sets in a row, a stretch that dates back to her 4-6, 6-2, 6-3 fourth-round victory over Angelique Kerber at Indian Wells. It’s the longest set winning streak since Serena Williams also won 28 sets in a row between the final of the 2012 US Open and the quarterfinals of the 2013 Australian Open.
Up next for Swiatek in the semifinals of Stuttgart will be Liudmila Samsonova.
