Andy Murray’s Wardrobe Malfunction

On By Teresa Merklin

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

On By Teresa Merklin

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

On By Teresa Merklin

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

On By Teresa Merklin

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

On By Teresa Merklin

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.

1994 and Coco Gauff

On By Teresa Merklin

1994 was a profoundly important year for Coco Gauff. It is an odd claim to stake for a player that wasn’t born until 2004. The events that unfolded in Women’s professional tennis in 1994 triggered a cavalcade of commissions and panels to study the long term effects on the lives of girls who played on the professional tennis tour while still in their early teens.

Best of Five and the WTA

On By Teresa Merklin

I was sitting at a computer in my local public library when realized that this project had transformed from a casual hobby into borderline obsession. For the first time I was compelled to step up the research beyond materials that I either owned or could access directly on the internet. “Best of Five” set matches for women was the topic that precipitated that transformation.
