Mayer, Monaco saunter through

Fifth seed Mayer lost just one game as he crushed France’s Stephane Robert 6-0 6-1, while Monaco, once ranked in the world’s top 10 but now sitting 60th, was also relatively untested in a 6-2 6-2 victory over compatriot Maximo Gonzalez.

The pair will meet later this week with a place in the quarter-finals at stake.

Italy’s Paolo Lorenzi also booked his spot in the last-16 after defeating Thomaz Bellucci of Brazil 6-4 6-7 (5/7) 6-1.
