ATP and WTA singles matches settled with a winner, imported live since 1 January 2021, doubles excluded. The favourite is the player with the lowest Pinnacle opening odds; matches without odds or with equal odds are left out of the rates that depend on them. Duration is only known for part of the matches, stated each time. The rank at match time comes from the profile computed before the match, never from the current ranking. Sets are decoded from the final score; only completed matches count. Retirement: a score containing “ret.”, “w/o” or “def”. The full methodology.
