CoCo Vandeweghe’s Viral Warm-Up

On By Teresa Merklin

One of the most culturally distinctive differences between tennis and other sports is how opponents are expected to cooperatively warm-up with each other prior to competition. It is a really strange practice when you think about it. A couple of week’s ago at the Koser Jewelers Tennis Challenge, Coco Vandeweghe tired to refuse to warm-up when her match resumed following a suspension for extreme heat. When the umpire and her opponent forced her to warm-up anyway, she petulantly refused to expend any effort.

Let’s Talk a Little More About Hindrance

On By Teresa Merklin

Last Wednesday’s “The Rules of Tennis” post drew a couple of comments that compel me to follow-up. In case you missed it, an umpire called hindrance call against Daniil Medvedev for apologizing to Alexander Bublik during a point in Toronto. This site’s (somewhat) sequential march through the rules of tennis has yet to reach the section of the USTA Friend at Court about talking during a point. Because it is current and relevant, we will jump ahead. It is a case where the written rule diverges significantly from how it is normally carried out in USTA sanctioned matches.

A Hella Hindrance in Toronto

On By Teresa Merklin

There was an unusual call last week in a match between Daniil Medvedev and Alexander Bublik. Medvedev lost a point for apologizing to Bublik after almost decapitating him with an overhead. Miraculously, Bublik got a racquet on the ball and returned it. The umpire called hindrance on Medvedev for saying “Sorry” when the point was still in play.

Court Pace Index

On By Teresa Merklin

There are no requirements in the ITF Rules of Tennis regarding Court Pace Ratings and Certification. The ITF programs that provide those measurements and assessment services are in support of court construction, rather than rules conformance. It is understood that there will be a wide range in the speed of various court surfaces. If you have watched a professional match that included a court speed graphic, the odds are very high that it was not the ITF Court Pace Rating at all.

Court Pace Ratings

On By Teresa Merklin

The section on Classification of Court Pace is found in Appendix I of the ‘ITF Rules of Tennis’ which is published as a part of the USTA ‘Friend at Court.’ It provides some basic information and references out to the ITF technical manual that provides excruciating details of the test procedures. Today’s post narrowly focuses on what is contained in the actual tennis rules. It is interesting but largely irrelevant to actual match play.

Tennis Ball Durability Specifications

On By Teresa Merklin

There are specifications for ball durability codified in the ITF Rules of Tennis. The durability requirements are provided in an unnumbered table in Appendix I. There are conformance parameters for mass, rebound, forward deformation, and return deformation. The durability testing performed by the ITF uses laboratory equipment that simulates nine games of play.
