An engineer overthinks tennis in a daily journal.
The ITF Rules of Tennis includes a detailed appendix that describes procedures for inspection of ball marks for line call verification when tennis matches are played on clay. Today we are examining what happens if the line umpire or chair umpire can’t find the mark. Additionally, this rule also covers the situation when the actual mark is not readable.
In an officiated tennis match, the chair umpire cannot delegate ball mark inspection to a line umpire. The rules are explicit that only the chair umpire may perform that duty. The ITF Rules of Tennis stipulates that the umpire is also supposed to physically climb down from the chair to actually make the inspection.

Ball mark inspection by the chair umpire only applies to tennis matches played on clay courts. Additionally, the rules stipulate the times when ball mark inspection is allowed to occur. The clay court inspection procedures also provide the foundational philosophy underpinning modern electronic line challenge systems.

This week I learned that the procedures for inspection of ball marks to confirm or overrule line calls only apply during clay court play. Anyone who has played tennis on a hard court in Texas following a dusty windy day has experienced what I call “West Texas Clay.” It is pretty common around these parts to play on outdoor hard courts where the ball leaves a discernible mark. Additionally, depending on how indoor courts are maintained, tennis ball fuzz can also leave clear bounce marks on the court.

The final Case Decision in the “Role of Court Officials” section of the ITF Rules of Tennis is mysterious in a couple of ways. First, imagining how the scenario could even happen requires significant mental gymnastics and I am unable to find any evidence that it has ever actually occurred. Additionally, the interpretation of tennis law seems straight forward which leaves me wondering why this Case is even included.

Tennis played with a full cadre of line officials is a privilege typically reserved for tour level professional matches. With electronic line calling becoming more and more prevalent, even that may soon be a relic of the past. Sometimes people make mistakes, and there are provisions in the ITF Rules of Tennis for handling the situation when a call is made, but immediately corrected.
A clip of Denis Shapovalov yelling at the Italian Open crowd to “Shut the f*** up!” went viral last week. The incident occurred in his first round match against Lorenzo Sonego following a call that didn’t go his way after the umpire inspected a ball mark. The episode revealed that Shapovalov didn’t understand one of the fundamental rules of tennis.

Last week I wrote about an unusual point where a ball in play bounced off one of the sensors used by the FoxTenn line calling system. It happened at Estoril during the semifinal match between Sebastian Korda and Francis Tiafoe. After a week of overthinking that occurrence, I want to revisit this rules interpretation and implications. Additionally, the Estoril tournament posted a video of it in the interim and this gives me the perfect chance to share out that clip.
Last weekend in a semi-final match in Estoril, a ball struck one of the on-court sensors used by the FoxTenn line calling system. Sebastian Korda hit a ball that tipped the net cord and went almost straight up. Before the ball struck the ground it came into contact with one of the black boxes installed at the bottom of the net that houses the sensors/cameras. That unlikely occurrence presents an interesting case study of the rules.

Sometimes two players disagree on the current score during a tennis match played without an on-court official. The correct procedure to resolve the dispute is to roll back the score until they reach agreement on the score at a previous point in the match. Play is resumed from there. In fact, if a roving official is summoned to the court that is usually how resolution is achieved. If the score was previously announced by one player without objection from the other, that is generally regarded as a point of agreement.
