Zurich - Roger Federer will play only two tune-up events on clay in 2009, ahead of the only Grand Slam he has never won, the French Open.
The former world number one Federer said on his website that he will play at the Madrid and Rome 1000 Series (formerly Masters Series) events ahead of the May 24 French Open start in Paris.
Switzerland's Federer played four events on the dirt this year, but was beaten for the third time in a row by new number one Rafael Nadal of Spain in the Roland Garros final.
Clay is his least favourite surface.
