Why surface matters more than ranking right now
Hard-court swings have compressed the rankings. Here's how to read form across surface changes.
The rankings have compressed over the last twelve months, and the surface split is the cleanest read on why. Hard-court swings have driven most of the points movement, with the clay-court specialists holding their ground and the grass-court swing having a smaller impact.
What the surface split tells us
- The clay-court specialists have held their ground through the surface changes, with the win-rate on clay the highest of the surface splits.
- The grass-court specialists have moved up the rankings through the swing, with the win-rate on grass the second highest.
- The hard-court specialists have moved up the rankings through the swing, with the win-rate on hard the most variable.
How to read form across surfaces
The form read should be surface-by-surface. A player who has won 80% on clay and 50% on hard is not in "average form" — they are in clay form and average-on-hard form. The surface-by-surface read is the only way to make sense of the rankings compression.
What we're watching
- The clay-court swing in April-May, which will set up the French Open.
- The grass-court swing in June-July, which will set up Wimbledon.
- The hard-court swing in August-September, which will set up the US Open.
