Indian Wells (United States): Andy Murray suffered a shock exit at the hands of Federico Delbonis in the third round of the BNP Paribas Open.

World No 2 Murray, who helped Great Britain to a Davis Cup win over Japan last week, lost a third-set tie-break to bow out, with Argentina's Delbonis claiming a surprise 6-4, 4-6, 7-6 (7/3) win.
It prolongs Murray's poor record at Indian Wells and the Scot admits it is not his favourite venue.
"I think it's just the conditions here I have just struggled with throughout my career. I have never really felt that I played my best tennis here," Murray told the official BNP Paribas Open website.
"I have tried and had many different preparations where I've got here early and spent a lot of time on the courts, and sometimes I arrive later, like this time from the Davis Cup.

"Obviously it takes time to get used to new conditions regardless of where it is, but I have just never really found a way to get comfortable here throughout my career. It's a shame."
There were no such problems for third seed Stan Wawrinka, who made safe passage past Andrey Kuznetsov.
Raonic in fourth round
The Swiss broke in the 10th game to take the first set 6-4 and then battled back after Kuznetsov was serving for the second set to take it in a tie-break.
Sixth seed Tomas Berdych disposed of Borna Coric in straight sets, winning 6-1, 7-6 (7/3), while Australian Open semi-finalist Milos Raonic booked his place in the fourth round when Australian Bernard Tomic called time on the game due to a wrist injury with his opponent 6-2, 3-0 to the good.
There were straight-sets wins for Marin Cilic and Gael Monfils, who beat Leonardo Mayer (6-4, 6-3) and Albert Ramos-Vinolas (6-1, 6-3) respectively.
