One final reached, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 6 semifinals. 23 quarterfinals.

By format — best-of-five: 19–26 (42.2%); best-of-three: 104–115 (47.5%). Slightly stronger in three-set contests, though the five-set record is still respectable.
