The 2018 schedules (announced on Oct. 12; a few links began appearing on Oct. 27; Winter Series mostly complete as of Nov. 7) :
The USA men captured seven of the ten available World Super-Seniors Individual Championships in Lake Nona FL. King Van Nostrand (80) and George McCabe (85) distinguished themselves by taking gold in both singles and doubles (McCabe partnered with John Powless). Congratulations also to doubles winners Dan Grossman (65), Richard Johnson/Jimmy Parker (70) and Fred Drilling/Michael Stewart (75).
USA men fared less well in the World Senior Individual Championships winning just one of six outright (Mike Fedderly in the 55 singles) and sharing another (Ross Persons in the 60 doubles with an Australian partner).
Here's the future of tennis rankings: the stronger the opponent you've just whipped, the more your own rating would improve. That's the sensible idea behind Universal Tennis Rating ̶ a ranking system already in use for juniors and collegians.
