If you are talking about his challenger results, he won the Bermuda challenger in 2008, beating the likes of Gulbis and Troicki. He also reached the finals in the Carson challenger in 2007 (and lost to Young).
On the ATP level, he reached SF twice, in Delray Beach (which he won) and Stockholm in 2008.
