With so much tennis going on during the Wimbledon Championships, one of the most difficult tasks is to make sure that each match has officiation of the highest standard. This thankless task falls to Wimbledon’s umpires, who supervise more than 650 games of tennis during the Wimbledon fortnight.
In total there are 335 officials who take control of proceedings at Wimbledon, in positions such as line judges, match umpires or off-court support staff. This contingent is made up of 275 homegrown British officials, all of whom are members of the Association of British Tennis Officials, and 60 further officials from around the world. Included in this group are all seven members of the ITF\Grand Slam Chair Umpires, who umpire at all four of the Grand Slam tennis tournaments to ensure the highest possible standard.
At the beginning of each day, the umpires are designated their various roles. Around 45 Chair Umpires, the most high profile role available, are selected, with the remaining officials then being broken up into teams to work as line judges and support staff. At any one time, a team of seven line judges work on the ‘outside’ courts while a team of 10 line judges officiate on the ‘show’ courts of Centre Court, Court One and Court Number Two. Although a chair judge will remain in his spot for the duration of a match, the line judging teams work on a rotation of 75 minutes on, 75 minutes off.
