Former world No.64 Ryan Sweeting has announced his retirement after a troublesome couple of years. The Caribbean-born American enjoyed a successful junior career where he reached No.2 in the world and won the 2004 US Open boys' title, defeating Jeremy Chardy.
On the pro tour, he achieved his career high in 2011 when he beat Kei Nishikori to win the Houston Open, the only ATP title in his career. He has also claimed three Challenger titles between 2008-2010 (Rimouski and twice in Dallas).
In the Grand Slams, Sweeting failed to replicate the success of his junior years as he failed to progress beyond the second round at any tournament. Towards the end of his career, Sweeting was plagued by back problems which forced him out of competition for an extensive period.
In September 2013 he underwent a procedure on his back. Returning to the tour the American has endured disappointment on the court, with his last tournament quarter-final (singles) being at the ATP Champaign Challenger in November 2012.
Despite the troubles on the court, Sweeting struck lucky off the court, marrying The Big Bang Theory star Kaley Cuoco. The two married in December 2013 after dating each other for six months. Sweeting confirmed his retirement on his official Facebook account.
