Medvedev upset by Monfils at Indian Wells, loses world No 1 ranking to Djokovic

Daniil Medvedev was sent crashing out of the ATP/WTA Indian Wells Masters in a stunning defeat to Gael Monfils on Monday that ended the Russian's three-week reign as world number one.

On a day of upsets in the California desert, Medvedev was the highest profile casualty to be sent packing, outfoxed 4-6, 6-3, 6-1 by veteran Frenchman Monfils.

Monfils sealed victory in 2hr 6min after converting his sixth match point.

"I'm in my zone and I'm a tough opponent for anyone," Monfils said. "It's been a long time since I've beaten a world number one, so I'm pretty happy."

Reigning US Open champion Medvedev had looked to be in control after taking the first set immediately after breaking Monfils for a 5-4 lead.

Medvedev said he would aim to reclaim his number one ranking at the Miami Open next week.

"Now I know I'm going to lose it (the ranking), so I have Miami to try to get it back," Medvedev said.
