One of the most underrated matches of recent years this one, imo. Great contest, truly befitting of a Davis Cup deciding rubber. Shame Del Potro wasn't fit enough at the time to extend it to 5 sets as he outplayed Rafa for large chunks of the match, but still a great effort. Rafa was his usual life, weathering the storm and coming through with his superior fitness and defense, not to mention some spectacualar shots from seemingly impossible positions.
It wasn't his fitness, it was his mentality. I remember he missed those easy FH sitters at *5-3 30-0 to get broken
But +1, it was truly a sensational match.
