If there’s any prizes at any Wimbleton tennis tournament, or for that matter any tennis tournament, they should go to the line-judges.
Spare a thought for these guys. Apart from being chastised and having the crowd howling in your back for a wrong decision, one can sometimes even have a racket threateningly waved in your direction with expletives included, as one unfortunate line-judge discovered when she called against Serena Williams at the US Open in September.
That aside, when a 150mph ball is hurtling towards you, thats like a car heading at twice the speed-limit at you. Surprisingly, there has not been much reports of injuries..hence no neccessity for face-masks and the like.
Eye injury seems to head the list, although there was a report about a groin injury (OUCH!) with subsequent blockage of the femoral artery nearby. The only reported death was during a Stefan Edberg vs John McEnroe game in 1983 when Edberg struck the groin of the line-umpire while sitting, causing him to topple over, leading to a head injury from which he subsequently died from..
