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.
2 responsesBall 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.
3 responsesThis 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.
1 responseThe 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.
