Federer and Wawrinka in early exits

World number two Roger Federer and defending champion Stan Wawrinka both suffered third-round defeats at the Monte Carlo Masters.

World number nine Wawrinka, the 2014 Australian Open champion, beat fellow Swiss Federer last year to win his first and only Masters 1000 title.
But he lost 6-1 6-2 to Bulgaria's world number 11 Dimitrov in 54 minutes.
Second seed Federer was beaten 6-4 7-6 (7-5) by Frenchman Gael Monfils, the world number 18 and 14th seed.
