Andy Murray wilts as Federico Delbonis fights back at BNP Paribas Open at Indian Wells
Andy Murray suffered a shock defeat at the BNP Paribas Open at Indian Wells when he blew a third set lead to go down 6-4 4-6 7-6 to Federico Delbonis.
Delbonis, who progressed to the third round, raced into the ascendency with an early break before holding his nerve to win the first set.
The world number two stormed back to break his opponent in the final game of the second set to win it 6-4 and then seemed to be in cruise control.
But despite being 4-1 up in the third, Murray wilted, allowing Delbonis to come back and take the match on a final set tie-break 7-3.
Novak Djokovic made a slow start as he launched his bid for a third title with a 2-6 6-1 6-2 victory over American qualifier Bjorn Fratangelo.
Johanna Konta eased into the last 16 with a straight-sets victory over Denisa Allertova.
Konta, seeded 25th, secured a 6-4 6-1 win over the Czech, who had seen off Australian Open champion Angelique Kerber in the previous round.
Rafael Nadal is planning to take legal action against the former French sports minister who accused him of doping and warned he will do likewise against anyone who makes similar claims in the future.
Roselyne Bachelot, the ex-Minister for Health and Sport, last week alleged that when Nadal was sidelined by a knee injury for seven months in 2012 it was actually because he had tested positive for a banned substance.
It is not the first time the 14-time grand slam winner has had to face such rumours.
Nadal said: "There is a couple of times that I've heard comments like this and this is going to be the last one, because I'm going to sue her. I've let it go a few times in the past but not any more."
