Serena Williams' demise turned the ripples into shockwaves at a French Open full of surprises as Maria Sharapova assumed the mantle of title favourite.
Williams' 6-2 6-2 defeat by Spain's Garbine Muguruza was the biggest shock of a tournament ridden with upsets in both the men's and women's draws.
The world number one went into the tournament as a huge favourite to retain the title she won for the second time 12 months ago.
But, within an hour of her sister Venus losing to Anna Schmiedlova, Serena trudged off the court a beaten woman. The pair had been expected to meet in the third round.
The result was surprising enough but the manner of it added to the shock. The 32-year-old had never previously won fewer than five games in any grand slam match.
