He was interviewed when he beat Jerome Haehnel yesterday.
Mathieu: "After the doubles yesterday with Gael, it was tough on the legs. I also sat all weekend throughout the Davis Cup, so it's not ideal preparation for the tournament. My legs were pretty heavy. I got off to a slow start, and he's a tough player. The important thing is to get the win and have another chance to play again tomorrow."
About his career high ranking: "I was told yesterday. It's a great feeling, especially as I haven't really had any really strong results or won any tournaments, unlike in 2002. It means that I've got the potential to go a lot higher still. I feel like I deserve this ranking."
