Fiend at Court Structural Changes Redux

Long time followers of the Fiend at Court will be aware that this site was originally created as an outlet for a daily goal I had established for myself to write a page a day about tennis. At the onset, I was concerned that it might be struggle to come up with enough ideas to fill a page each day. The training wheels phase of this project used a sequential walk through the Rules of Tennis as a daily prompt.

Revisiting an NTRP Horror Story

In 2020, this site published “NTRP Horror Story: When the Carrot becomes a Stick.” That post was my own personal account about abhorrent player behavior in a USTA League match. A the time, I made the assertion that the incentives attached to the NTRP system were a contributing factor in the unsportsmanlike conduct. Today I have a tiny coda to that saga.

The Apples and Oranges of USTA and UTR

A shockingly high number of tennis players can’t articulate the difference between the USTA and Universal Tennis. In fact, Universal Tennis sometimes doesn’t even ring a bell for players. Most tennis players have heard of the the Universal Tennis Rating (UTR) system and use that acronym as a stand in for Universal Tennis. For the sake of simplicity, I sometimes refer to Universal Tennis as UTR. When in Rome.

Andy Murray’s Wardrobe Malfunction

Remember that time when Andy Murray couldn’t keep his balls in his shorts? In 2012, there was an issue with Murray’s clothing that resulted in tennis balls accidentally falling out of his pocket during points. The recurring hindrance calls forced Adidas to make a mid-tournament update to his shorts to address his issues. It is an interesting case study in a hindrance caused by something that is within a player’s control yet still unintentional.

Six Weeks with Dennis Ralston

Fiend At Court spent a virtual six weeks with Dennis Ralston in 2020. To be more precise, this site spent six weeks on a structured improvement program inspired and derived from Six Weeks to a Better Level of Tennis, a book he authored with Barry Tarshis. Unfortunately, Ralston passed away last month following a long battle with cancer. Revisiting the Fiend at Court “Six Weeks” project became compulsory with his passing.

The COVID-19 Tangent

There are no rules specific to the control of infectious disease in the 2020 ITF Rules of Tennis. The same can be said for the USTA Friend at Court. That is not a surprise because when both of those publications were released last year, COVID-19 was not yet a major concern. As a result, COVID-19 has the distinction of being the first content on this site that was completely unrelated to the ITF Rules of Tennis.

Learning to Love the Early Icons of Tennis

When I first embarked on the project manifested by the Fiend at Court site, I would have asserted that I have little personal interest in the early history of international and professional tennis. The first appearances of early tennis stars in what was published was in the context of newspaper articles summarizing proposed changes to the ITF Rules of Tennis of their time. I am embarrassed to say, that some names that I did not initially recognize are now turning up repeatedly in the tennis books of their era.

Revisiting the Racquet Toss

The method of deciding the choice of ends and server was a detail that brought me to a full stop during last year’s march through the ITF Rules of Tennis. I was surprised that a particular method of deciding the choice is codified directly into the rules.

The choice of ends and the choice to be server or receiver in the first game shall be decided by toss before the warm-up starts.
