The draw lists every main-draw match the record holds for the season, deepest round first, the winner named first with the score as his line reads. A retirement prints the sets that were played and the word; a walkover prints no score, because nothing was played, and is counted in nothing. Qualifying is not in the record. Ranks are the tour’s ranking on the day of the match.
