The Aegon championship has been full of surprises thus far with in form Spaniard Rafael Nadal being knocked out in the very first round by Ukraine’s Dolgopolov. The second rounds were no different as defending champion, Grigor Dimitrov, suffered a heavy defeat by the hands of Giles Muller of Luxembourg in straight sets on Thursday.

Muller, aged 32, hit 19 aces as he convincingly beat his opponent 6-4, 7-6 (7-5) to reach the quarter finals at Queen’s. The world number 48 will face Andy Murray, who himself, is high on confidence. The Brit overcame a resilient Fernando Verdasco in straight sets beating the Spaniard 7-5, 6-4. The top seed remains on course for a fourth Queen’s Club title after a hard fought win in round two.

Dimitrov, who crashed out of the first round of the French Open just weeks earlier, was devastated by his loss. “It hurts. It always does. It’s a tough loss for me, but I give credit to Giles. He really played well,” said the defending champion.

Meanwhile, Andy Murray is hoping to win his 4th Aegon Championship. The much anticipated quarter final will take place today.
