Losing to Berdych on clay is not exactly a good thing and that happened only last year. Berdych is not your traditional clay courter. He's more known as a hard courter though he has a tiny title on clay. Also, Berdych won this title back in 2005 while Andy never made past qtr final here. Apart from Federer and Novak, Berdych should be his toughest opponent. Andy will have to be in the match right from the start.
Of course Andy is playing much better this year especially lately but still, Berdych may just come out firing. In that case, the only thing that can go wrong for him is that, he's a bit of a choker and Andy is a smart player. I am still picking Andy and possibly in two sets but it might not be as easy as his today's match.
People wouldn't say that clay is Andy's favoured surface but he's come on leaps and bounds since then. Berdych had a good run last year.
Berdych's run to the final in 2005
En route to the final, he beat Jiří Novák, second seed Guillermo Coria, 13th seed Juan Carlos Ferrero, seventh seed Gastón Gaudio, eighth seed Radek Štěpánek, and sixth seed Ivan Ljubičić in the final, 6–3, 6–4, 3–6, 4–6, 6–4.
Andy knows the task ahead and body permitting, I'm sure that he'll be up for it.
