Keys closes it out in the second

The 15th seed then held easily to love, before Vekic got herself on the board for 3-1. The world number 17 then kept up her fine form on serve, using her big first delivery to set up a nice and easy volley for 4-1.
The unseeded Croatian's struggles on serve continued, with Keys breaking again off a Vekic backhand error. With Keys serving for the match, the world number 96 upped her game to stop the rot, breaking the 15th seed courtesy of a double fault from the American. With the pressure on the young Croatian to serve to stay in the match, Keys played a brilliant return game to force the nerves of Vekic to show, with the match ending off another double fault from the 19-year-old, with Keys emerging victorious 6-3, 6-2 to move into the second round at Roland Garros.
