Madison Keys’ coach names the WTA player he thinks has the potential to be world number one if she stays fit

The American WTA Tour star grabbed all the headlines in January as she put on a tennis masterclass at Melbourne Park.

Keys beat Aryna Sabalenka in a spectacular final, 6-3, 2-6, 7-5, in front of a packed-out Rod Laver Arena.

There was more to her Australian Open story than the final, however, as the 29-year-old took down several top stars during her stint down under.

Iga Swiatek, Elina Svitolina, and Danielle Collins were all seeded in Melbourne but were no match for Keys who powered her way into the final
