He been ranked in the top 400 twice before. Once in 2006 before he went back to Uni and then again in 2009 after he returned.
Surprised you've nevered heard of him before.
Hate to admit this, but I really only took an interest in tennis when Andy came on the scene, but, now that I have, I find it really exciting and like several players though Andy is my 'main man'! Now, I'll watch Colin with interest too! Thanks for the info!
