It was the 105th edition of the annual Monte Carlo Masters tournament, which was sponsored by Rolex for the third time. It took place at the Monte Carlo Country Club in Roquebrune-Cap-Martin, France, near Monte Carlo, Monaco.
On 11 April, an exhibition featuring two players from the Women's Tennis Association, current world number one Caroline Wozniacki and reigning French Open champion Francesca Schiavone, took place during the traditional women's day at the tournament.[1] Schiavone won the one-set exhibition match 6–4.[2]
Because the Monte Carlo Masters was the non-mandatory Masters 1000 event special rules around the point distribution happens. Monte Carlo Masters counted as one of a player's 500 level tournaments, while distributing Masters 1000 points.[3]
