Re: All-Time QF or better than that
I think that you has forgotten Roddick.
Australian Open: 3; twice semifinalist (2003 lost to Schuettler, 2005 lost to Hewitt), 1 QF (2004 lost to Safin)
Wimbledon: 3; twice finalist (2004 lost to Federer, 2005 lost to Federer) once semifinalist (2003 lost to Federer)
US Open: 4; champion (2003 defeated Ferrero), three times QF (2001 lost to Hewitt, 2002 lost to Sampras, 2004 lost to J.Johansson)
At least 10 I think.
