What is missing here

  • Fajing Sun is unrated on hard: fewer than 5 matches in our history, so his rating here falls back to his overall level. This also blocks any market comparison for this match.
  • Fajing Sun's ATP ranking could not be confirmed against this week's list, so it is used with less confidence.
