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.
