David Ferrer was on the receiving end of a giant killing in Barcelona yesterday as the Spaniard crashed out of the ATP 500 event to 30-year-old Dimitar Tursunov in three sets.

Tursunov was playing his first clay court game of the season, but he showed no mercy when battling David Ferrer early on Tuesday. Tursunov was ruthless during the first set firing forehands all over the court putting constant pressure on the Spaniard who really struggled with his game.

The second set started off just like the first, with an early break for the world number 66 and Ferrer almost looked to be a beaten man. 

However, as so many times before, he came back and turned a 3-1 lead for the Russian into a 6-3 set win for himself. All of a sudden it surely looked like Ferrer had gotten the better of Tursunov.

The third set was shocking in every aspect for the number one seed as the Russian once again got the early break. This time he kept the advantage all the way until the very end of the match as he sealed an amazing victory 7-5 3-6 6-1. 

Speaking to ATPtour.com after Tursunov said: “It wasn’t Ferrer’s best match. He didn’t play his best tennis.

"He had the advantage over me because he's been playing on clay. But I played very quickly and I didn't make it easy for him. 

“Ferrer was the favourite based on surface and ranking. It was a match where there were a lot of opportunities for both players."  

Tommy Robredo, who got the better of youngster and rising star, Grigor Dimitrov, caused another upset. 

Robredo was down 5-2 in the first set, but from that point of the game, he won 11 of the remaining 12 games to secure a spot in the next round through a 7-5 6-1 victory. 

In addition big serving Milos Raonic easily won his match versus Eduardo Roger Vasselin in straight sets victory. The 22-year-old Canadian breezed through with a 6-4, 6-2 win.

Clay court specialist Juan Monaco who has had major problems finding his game during the first months of 2013 now looks to improve from week to week as he advanced into next round in style. 

He had an easy tie against the youngster Bernard Tomic and made no mistake of it, defeating him 6-0 6-2.

In the second tournament of this week, an ATP 250 event taking place in Bucharest, the most surprising result was seeing Lukas Rosol beating third seed Andrea Seppi in three sets. 

Rosol played close to his best during the first set and easily won it 6-1. Seppi then came back in the second to force a third. It was to little avail though as he eventually lost when Rosol served out the match with a rocket ace. 6-1 3-6 6-3

Gilles Simon from France also began his title defence in Bucharest with a very hard fought win over Jarko Nieminen in 2 hours and 40 minutes. It was a high quality game with the Frenchman coming through in the end, 4-6 6-4 6-4. 

He told ATPtour.com: "I won so many matches on this centre court, so whenever I step on it I have a lot of confidence. Even if I feel tired before coming here, I don't want to miss this event because I always feel great here. I’m happy with the way I played the last game today.”

Simon will now face German Daniel Brands, who knocked out Simon's fellow countryman Gael Monfils in the previous round.
