Qatar Open: Nadal comeback ends in loss to German journeyman

Rafael Nadal's season got off to a miserable start as his comeback from injury and illness stalled in the Qatar Open first round with a 1-6, 6-3, 6-4 defeat by German journeyman Michael Berrer on Tuesday.

The Spaniard, who endured a stop-start season during the latter half of 2014 after suffering from a wrist injury and appendicitis, looked on track for a promising win when he took the first set at the warm-up event for this month's Australian Open.

However, 127th-ranked Berrer came out firing winners to all corners of the court to pull off his first victory over a top five player.

"These things happen after a long time without being on the road... being in competition. I was playing with more nerves because after a long time away I wanted to win," world number three Nadal told reporters.

"My motivation and my hunger to keep doing things well is still the same."

Although the 34-year-old German achieved the remarkable feat in his final season on tour, he did not get too carried away by the result.

"It's really unbelievable," said Berrer, who until Tuesday had won just four games against the former world number one.

"Losing 1-6 felt like the other matches against him so I had to do something. It's my last season, I'm going for it, I have nothing to lose, I'm enjoying it here so why not.

"It's one of the matches that will stay in my memory but, let's be honest, it was the first match for Rafa after many months of injuries, so we have to be realistic. But for me great."

Nadal had three break points to level the third set at 5-5 but despite jitters from Berrer, who served two double faults trying to close out the win, the German hung on to watch his opponent whip a service return wide on match point.

While 14-time Grand Slam champion Nadal must turn to plan B to get ready for the season's first major, having produced 32 unforced errors, there were no such problems for Novak Djokovic who polished off fellow Serb Dusan Lajovic 6-2, 6-1.
