It seems playing Rafa on clay is harder than we thought. It his semi with Rafa, after initially feeling some pain in the quarters, Federer has admitted to having some minor injury which was the reason he flexed his arm repeatedly during his semi with Rafa.
“I had muscle pain since the first game, not only in my chest. It’s actually better than yesterday but I just feel that when I keep on serving and then the match extends and I haven’t served in maybe five to 10 minutes sometimes.
I was still able to hit full speed which is most important and I didn’t double fault much so it was fine.”
