I salute you Andy Roddick, you have been a great ambassador to the sport and will always be one of my favourite players. I feel sad that you have chosen to retire but I wish you all the best.
An edited list of Roddick's achievements;
World No.1 (in 2003)
2003 US Open Champion
Finals of 4 other Grand Slams (04,05,09 Wimbledon and 06 US Open)
$20+ million in career prize money
609-212 w/l record (still counting)
Made 9 Masters Series finals winning 5
*I enjoyed looking back at Roddick's achievements so much I might do some profiles of other retired/current tennis players in the future.
