LONDON (AP) — The number of players competing in professional tennis events will reduce drastically following a major structural shake-up aimed at helping more competitors earn a living and improving the pathway from junior level to the top of the sport. In a move that could see the number of players competing professionally decrease from 14,000 to 1,500, the ITF has approved the introduction in 2019 of a Transition Tour that features localized entry-level events to "better aid the transition from junior to professional tennis."
