Andy Murray claims the grass at Wimbledon could slow the ball significantly after the recent rain deluge. The weather forecast calls for rain during much of the first week. "The court's slow now," the fourth seed told reporters. "So a lot of the guys that weren't playing well on the grass four, five years ago I think are playing better. There are a lot longer rallies, so it gives the baseline players a lot more chances to cause upsets. Especially if the weather stays like this. When it's cold, it's one of the slowest courts in the year. That isn't an exaggeration."
