02/Every meeting
1 row, newest first
A record, never a share of meetings. Main-draw singles since 2013; a meeting ended by retirement is counted with the sets that were played and marked; a walkover is listed and counted in neither column. Otte O. and Harrison C. each carry the table against every opponent faced.
