Monfils makes winning start

The flamboyant Frenchman hit 18 aces in the 7-6 (7-6) 7-6 (7-5) second-round success, which took 87 minutes.

Monfils was playing his first grass-court match of the season after reaching the fourth round of the French Open where he was beaten in four sets by Roger Federer.

He will face sixth seed Philipp Kohlschreiber in the quarter-finals, following the German’s 6-4 6-4 success over Jerzy Janowicz.

Eighth seed Viktor Troicki saw off Alexander Zverev 6-3 6-7 (6-7) 6-3 to book a quarter-final clash against Sam Groth, who edged out third seed Feliciano Lopez 3-6 7-6 (7-5) 7-6 (7-6).
