David Nalbandian admits his disqualification from the Queen's Club final for kicking an advertising board that left a line judge nursing a bloody gash in his leg was the worst moment of his career.
Former Wimbledon finalist Nalbandian booted the board into Andrew McDougall in frustration after losing his serve in the second set of yesterday's final against Marin Cilic.
The Argentine paid the penalty for his petulant actions as he was kicked out of the final moments later.
The fiery 30-year-old immediatley apologised for his behaviour during
an on-court interview after the match.
Nalbandian was leading 7-6 (7/3), 3-4 at the time of the incident and was clearly genuinely upset that he had hurt McDougall.
And, Germany's Tommy Haas defeated second seed Roger Federer 7-6 (7/5), 6-4 to win the ATP grasscourt tournament in Halle.
Playing in front of his home fans, the 34-year-old added to his triumph in this event three years ago to take his 13th ATP title.
