Karin Khachanov v Juan Martin del Potro
A battle of the big-serving giants in this fourth-round encounter with the Argentine Juan Martin del Potro rightly rated as a strong favourite. The pair of them have been solid on serve all week, racking up the aces and more importantly, being rather frugal with break points offered.
In their previous three meetings, half of the eight sets have been tie-breaks, with no more than one clear break in any other set. I can't see either player wanting to make this a baseline grind, it'll be power all the way which is likely to mean a lot of quick service games. If Karin Khachanov can pinch a set along the way, then the games total could go nice and high.
Amanda Anisimova v Aliona Bolsova
Not quite the fourth round match people expected when first looking at the draw, but it's the world number 51 vs number 137 to finish the day on Court Suzanne-Lenglen, a show court these two will be very unfamiliar with.
17-year-old Amanda Anisimova won the Bogota title in April, possibly the weakest WTA event on the circuit, without facing any player ranked in the top 90. After reaching the fourth round in Melbourne on her preferred surface, her ambition here was merely hope rather than expectation. In three rounds so far, she has beaten a wildcard, a seed with minimal clay form and a former top 20 player at the tail-end of her career. Winning form is naturally good form, but don't get too excited by the depth of it.
Aliona Bolsova has come from nowhere to reach the fourth round and will see a big surge in her ranking when updated next week. She's not done with yet though, and in six matches so far including qualifying she's only dropped one set.
The former Florida Atlantic NCAA player is coached by former tour player Lourdes Dominguez Lino and recently appointed a psychologist whom she gives a lot of credit for her recent improvement. A gritty baseliner without a notable serve, she has been relentless on her break points, converting nine of 11 in her last two rounds.
The American teenager has the hype around her and rightly so, but on this surface I don't think she deserves to be such a clear favourite. Bolsova has been good for us so far and there might just be another win in her yet.
