“Updates” to the ITF Rules of Tennis

On By Teresa Merklin

Ever since New Year’s Day rolled around I have been eagerly anticipating the release of the 2022 ITF Rules of Tennis. As a blog that started with a rules oriented focus, it just kind of feels like the right thing to do. The ITF finally got around to posting the new document on their web site yesterday morning. After electronically comparing the differences between the 2021 and 2022 documents, I can confidently assert that there are no material changes to the ITF Rules of Tennis in 2022.

USTA League Partial Round Robin Rules

On By Teresa Merklin

Since formation of USTA League teams for 2022 is already in high swing, now is the perfect time to take an advance look at new rules which are expected to come into effect. The 2022 USTA League Regulations (apparently) have yet to be officially released. However, a draft document was circulated for review last June that is probably close enough for our purposes.

ATP Time Violations

On By Teresa Merklin

Last Wednesday we reviewed a new rule associated with toilet breaks that the ATP tour is implementing in 2022. It is a clear and direct response to the media coverage and backlash surrounding the toilet habits of Stefanos Tsitispas. Buried at the end of the ATP announcement of the rule, was an innocuous little sentence that the penalty for extended bathroom breaks are Time Violations.

Tiebreak Rules from the #NextGenATP Finals

On By Teresa Merklin

I have a complicated relationship with the Fast4 scoring system. I like it when playing UTR tournaments as the shortened format enables completion of a three match tournament in a single day. I don’t like it for competitions where a significant number of the competitors had to get on a plane to get there. This week how the tiebreak format is handled at the #NextGenATP Finals was added to the mix.

Rule Innovations at the #NextGenATP Finals

On By Teresa Merklin

The #NexGenATP Finals is a veritable tennis Petri dish. Every year new rules are unveiled at the event to see how they work in practice. The players playing in the event this year profess that they are excited about the innovations. In related news, the young American stars in the same pre-tournament press conference believe that they will contend for Grand Slam titles in the near future. What else are they going to say in either case?

Tennis Extinction Event: The Net Umpire

On By Teresa Merklin

Just as line calling officiating positions have been sharply curtailed with the advent of HawkEye Live, the net umpire position has similarly been a victim of progress in technology. Nets at professional tournaments are equipped with sensors that inform the chair umpire when a service let is detected. When Hawk-Eye live is used, the let signal is fed directly into that system for an audible call.
