Philip Bester gave an interview with Fan 590 which you can listen to here: http://www.fan590.com/media.jsp?cont...21_202318_8836
He talks about Davis Cup and claims that actually he likes playing on clay, even saying it is his best surface.
Unfortunately it turns out that he has a stress fracture in his hand. He was uncertain when he would be able to return, saying he is taking it week by week.
So that rounds things out for our injured top 5 players, with the full range of injuries: Hip, back, ankle, hand and groin.
