Stanislas Wawrinka, who looked sharp in a no-nonsense 7-5 6-4 win
over Frenchman Edouard Roger-Vasselin.
Nadal, who has reached the final three times but never lifted the
Miami title, blew past Lleyton Hewitt in the second round before

Next up for the Spaniard is a fourth round meeting on Tuesday with
Italian 14th seed Fabio Fognini, who advanced with a 4-6 6-3 6-3
comeback win over Spain's Roberto Bautista Agut.
