There is no injury or withdrawal feed for tennis that we can read, so nothing here says whether a player is fit. Matches played and days off the court are the observable proxies, and a long gap can equally mean a break in the calendar.

We hold only 7 completed matches for this player, so every figure above rests on a small sample. Ratings on surfaces with little history are pulled back toward the overall number rather than presented as if they were settled.

Surface ratings shown are effective Elo: the raw surface rating regressed toward the player's overall figure in proportion to how many matches sit behind it.
