Katerina Siniakova is a great doubles player on the WTA tour, but what is her racquet setup?
Katerina Siniakova’s tennis racquet
Katerina Siniakova’s racquet is a Wilson Pro Staff, but an older version with a 16/18 string pattern. This pattern is rare among Wilson’s racquets, but used to be a part of the Wilson Six One series (available in both 16/18 and 18/20). I guess her racquet is a Wilson Six One 95 16/18, but I am not quite sure. If you have information about Katerina Siniakova’s racquet, please comment below.
She strings her racquets with a hybrid setup of Luxilon 4G in the mains and natural gut crosses. This is a pretty popular setup among pros ont the ATP and WTA tour.
