Sania Mirza has set up a second round clash with tennis giant and second seed Venus Williams at the WTA Family Circle Cup.

Mirza edged past Sesil Karatantcheva 6-4 6-4 in the first round.

The Indian ace, fresh after her doubles title win at a Florida WTA event last week, took one hour and 16 minutes to dispatch her opponent from Kazakhstan.

The encounter saw plenty of breaks being traded and Sania converted more chances to advance to the next level.

The Indian broke her rival three times in the first set and saved four breakpoints apart from dropping her serve twice.

In the second set, Sania raised her game and converted both the breakpoints that came her way en route to the victory.

The road becomes extremely tough for Sania hereafter as she is now up against world number five Venus, against who she has lost both of her previous encounters.
