Organizers probably think Gasquet has a better chance on the much slower court of Suzanne Lenglen. They had Monfils play Roddick there last year as well. (and I wouldn't be surprised if they put Monfils-Federer on Suzanne Lenglen as well, should it come to that match.)
Hmm sounds right. I was thinking they wanted to put him on a smaller court so he would feel less pressure.
They just want to have one frenchie on each court to satisfy all the ticket holders.
