Surbiton Marks The Start Of The Grass Season The Surbiton Trophy opens the annual three-week grass-court swing in the U.K. Located just outside of London, the 142-year-old Surbiton Racket & Fitness Club hosts the Challenger 125-level event. Past champions in Surbiton include former Top 10 stars Mardy Fish (2006) and Jo-Wilfried Tsonga (2007), with Lleyton Hewitt and Roger Federer contesting their first professional grass-court matches there in 1998 and 1999, respectively.
