HALLE WESTFALEN, Germany: Spanish world No. 1 Rafael Nadal suffered a shock second round defeat at the hands of German world No. 85 Dustin Brown on the grasscourts of Halle on Thursday.

The right-handed Mallorca native, fresh from his ninth French Open title last Sunday, crashed 6-4, 6-1 at the hands of the lanky Brown who is still looking for his first ATP singles’ title.

The 1.96m (6ft 5in) Brown, who has won two doubles titles, picked up the biggest win of his career on the back of 11 aces and a winning first service percentage of 83 percent.

Nadal, meanwhile, forced just one break point against his opponent, which he failed to convert, while Brown broke three times on his way to victory in just under an hour.

Awaiting Brown in the quarter-finals is compatriot and 2011 Halle champion Philipp Kohlschreiber.

Earlier, Roger Federer got his Wimbledon preparations fully underway, but he looked out of sorts before finally edging Portugal’s Joao Sousa 6-7 (8/10), 6-4, 6-2 in a second round tie.

Playing for the first time since losing to Ernests Gulbis in the last 16 of the French Open, the six-time former winner of the German tournament started brightly but was soon on the backfoot against the improving Sousa.

There were no breaks of serve in the first set and it was Sousa who dominated the tie-break clinching it on his fourth set point.

Federer looked frustrated at times, but the match turned on the seventh game of the second set when Sousa’s level suddenly dipped allowing the Swiss great to pounce and secure his first break.

From then on it was all Federer with a break of serve in the first game of the deciding set sending him safely on his way into the last eight.

“I struggled a bit on return during a set and half,” said Federer. “Afterwards, it was better, more variation on second serve.

“It was slightly frustrating, but important to stay calm. Maybe I got more confidence winning this way than 6-4, 6-4.

“When I came here (Saturday) to start practice it was so-so, but now it’s better. For me, it doesn’t take a lot of time to get used to the grass.”

Third seed Milos Raonic of Canada lost on Wednesday 6-4, 6-4 to German wildcard Peter Gojowczyk.

Federer’s opponent in the quarter-finals will be Lu Yen-Hsun of Taiwan, who defeated big-serving Ivo Karlovic of Croatia 7-6 (7/2), 7-6 (7/3).

Misfiring Murray slumps to early Queen’s defeat

In London, Andy Murray’s hopes of recreating the joyous British celebrations after winning Wimbledon last July did not look too promising on Thursday as he suffered a surprise third-round exit at the Aegon Championships.

The manner of his 7-6 (10) 6-2 defeat by Czech Radek Stepanek would have done nothing to boost the British number one’s confidence as he squandered eight set points in the opening set before tamely surrendering the second.

The defeat snapped the world No. 5’s 19-match winning streak on grass, a sequence that started in 2012 with his run to Olympic gold in London.

New coach Amelie Mauresmo, a former Wimbledon champion herself, kept a poker face as the match headed toward a disappointing conclusion but she would have noted the challenge that lies ahead over the next 10 days before Murray opens Center Court proceedings at the All England Club on June 23.
