Wimbledon 2006
The spectators at Wimbledon were forced to pop their umbrelllas open
The match was interrupted three times in all -- twice by rain and once by two protesters who were quickly hustled off court -- but Federer's concentration was unbroken throughout.
Their only previous meeting on grass was that match in the first round in 2002, when Ancic won in three sets. Federer has won all three of their meetings since, including their French Open quarter-final last month.
