Andy Roddick to be coached by Stefanki

American Andy Roddick will be coached by compatriot Larry Stefanki ahead of the 2009 season.

Stefanki, who has previously trained John McEnroe, Yevgeny Kafelnikov and Tim Henman, was coaching Fernando Gonzalez until recently.

Roddick endured a disappointing end to 2008, withdrawing from the Masters Cup with an ankle injury.

The 26-year-old, who reached the quarter-finals of the US Open, ended the season ranked eighth in the world.

Stefanki played on the ATP tour for nine years reaching a career high ranking of 35.

He is regarded as one of the best coaches in world tennis and under his guidance, both Kafelnikov and Marcelo Rios became number one in the world.

Former British number one Henman teamed up with Stefanki in 2001 having split with David Felgate earlier that year.

However, their partnership lasted just two years, with Henman teaming up with Pete Sampras' former coach Paul Annacone in December, 2003.

Roddick has one Grand Slam victory to his name, winning the US Open in 2003, while also losing in three other finals.

Prior to Stefanki he had been coached by Jimmy Connors.

The pair teamed up in July 2006 but parted company earlier this year.
