Katerina Siniakova vs Peyton Stearns prediction

Peyton Stearns and Katerina Siniakova will lock horns for a third time when they do battle in Osaka.

The honours are currently even at 1-1 with the Czech winning their only previous meeting on hardcourt in their last showdown in Cleveland two years ago.

However, the American will be the favourite here and is almost 50 places better off in the rankings.

Indeed, Peyton recently finished as runner-up in Guadalajara while Siniakova has lost her last two and has not managed back-to-back wins since the grass swing.

That said, Katerina will feel she has the blueprint to cause problems and this may well be one with plenty of games to consider.
