Rafa and Novak's Grass woes

Rafael Nadal and Novak Djokovic head to Wimbledon fearing the title may be beyond them as the season's third Grand Slam tournament shapes up to be the most open in a decade.World number one Nadal, fresh from a record ninth French Open title will be keen to arrest his slide at Wimbledon the last two years. His last two visits have been humiliating disasters. The Spaniard suffered his first ever opening round exit at a Grand Slam in 2013 to Belgian journeyman Steve Darcis who was ranked 135 at the time and has not won a main tour match since.Twelve months earlier, the world's 100th best player, big-hitting Lukas Rosol put him out in the second round, a defeat which precipitated a even-month absence from the sport for the man from Mallorca. Interestingly Rafa is seeded number at Wimbledon 2014 behind Novak Djokovic.
