The matches won with the lowest chance of winning, week by week.
The win chance is from the ratings right before the match. Only matches between settled players count: every player has played at least 10 matches and has a rating certain to within ±250 in singles or ±180 in doubles, so a junior improving fast beating a favourite isn't counted as an upset. Walkovers and draws are left out.
