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. French world number 28 Monfils produced a vintage performance to down Medvedev 4-6, 6-3, 6-1 in just over two hours to advance to the fourth round. It was the first time the 35-year-old Monfils has beaten a player ranked world number one since 2009. The defeat means Novak Djokovic will return to the top of the world rankings, three weeks after Medvedev took top spot on February 28.
