How It Works

The Next Generation ATP Finals introduced several rule changes to assess their potential adoption in professional tennis. These modifications aimed to speed up play, reduce downtime, and appeal to younger audiences.

Best-of-five sets to four games: Matches were played in a best-of-five sets format, with each set won by the first to four games, reducing match duration.
No-ad scoring:No-ad scoring was used, meaning deuce points ended on the next point, speeding up individual games.
Shot clock: A 25-second shot clock was enforced between points, with visible countdowns to maintain consistent pacing.
Coaching allowed: Players could receive on-court coaching via earpiece, a first in professional men's tennis, limited to once per set.
Electronic line calling:All line calls were automated using Hawk-Eye technology, eliminating the need for line judges.
Medical timeout: A one-time, three-minute medical timeout was allowed, differing from standard ATP rules.

Comparison at a Glance

Below is a comparison of traditional ATP Tour rules versus the experimental format used in the 2018 Next Generation ATP Finals:

Rule Category	Standard ATP Rules	2018 Next Gen ATP Finals
Set Format	Best-of-three or best-of-five sets to six games	Best-of-five sets to four games
Scoring	Traditional scoring with advantage points	No-ad scoring; next point wins after deuce
