Yep and as Andy said after the Troicki match yesterday he is also a former French Open Quarter-Finalist. However that was a long time ago now, but is proof of Benneateau's clay credentials.
As EJ said, it mostly all comes down to Andy's performance. If he's on song like he was yesterday he should face few problems.
Andy has certainly started his clay season feeling very confident and this confidence is based on his performance last year. He maybe looking forward to playing both Nole and Nadal already as he feels the least pressure against them and this being clay makes it all the more worthwhile to give it a real shot. I guess we will see. His next match will be tough either way after Benneateau but not going to look any further than that for now.
Another note to take into account is that, Andy put forward a brilliant play in his first match here in MC and that’s over two weeks of break in between, whereas he was quoted as “undercooked” at the Miami final after only three days break in between and he played a couple of fairly competitive matches just prior. You can see how that undercook logic doesn’t really apply overall. Federer, I remember, strictly saying that it doesn’t bother his level of play even if he has to sit through 4 days in a row to play the next match – be it final or whatever. He says he still feels just as much anxious and eager to play. Again this mostly comes down to the mindset one has.
