The popularity of grass courts in the overall game, professional or club players (like most of us) has notably diminished. Grass courts are becoming less and less common as the tennis centres are mainly trailing over to the likes of hard court and clay or carpet.
It's swings and roundabouts.
There will be an extra week for the grass season from either 2014 or 2015 I believe, with the ATP introducing an extra week between RG and Wimbledon. Maybe they'll use this opportunity to introduce a grass court 500, although apparently Hamburg want to switch to grass.
