Serena Williams, the number one seed at the Top Seed Open will give fans a first glimpse of her form when she takes on Bernarda Pera first on Center Court today.

From a current great to a potential future great in Coco Gauff who follows that taking on compatriot, Caroline Dolehide. Like Williams, it is hard to say what shape the former will be in.

Dolehide has played qualifying in Lexington and so may hold a slim advantage in the early running having played herself into action.

Another top American in action is Amanda Anisimova who begins Court 2 proceedings today. Again hard to say with Cici Bellis looking good to begin the year and she could produce the shock here.

Two more big ties will take place on Center Court today with Venus Williams against Victoria Azarenka. The latter could be picked to win with Williams being on a downward trajectory but she has played more ranking tennis this year and so could be favoured albeit in a close tie.

Then it is Sloane Stephens who will take on a tough test in 17-year-old Canadian, Leylah Fernandez. The former lost to her at Monterrey after Fernandez had reached the final at Acapulco.

Straight forward wins over Zarazua and Rodionova saw her win through to the main draw and barring any brilliance from Stephens, it could yet again be Fernandez's day.

Yulia Putintseva against Ajla Tomljanovic and Shelby Rogers v Misaki Doi are also among the ties on the second day in Kentucky.
