Roddick: "Swiatek will win a host of Grand Slams on surfaces other than clay".

Iga Swiatek has won five Grand Slam tournaments, including four at Roland Garros.

Much more at ease on clay, the Pole has only won one Grand Slam on hard court, at the US Open.

Andy Roddick, on his 'Served' podcast, commented: "Iga is going to win a lot of Grand Slams on surfaces other than clay.

She will, she's only 23. Don't worry, everyone's better on one surface. That's not to say that Grand Slams are any less important.

And don't say that just because she's not as good on hard court as she is on clay doesn't mean she's not good on hard court.

Otherwise, she wouldn't be where she is today. But don't worry. Some people are better on different surfaces."
