Wimbledon: Electronic line calling system malfunctions during quarterfinal match

A malfunction with Wimbledon's new electronic line calling system required a point to be replayed during a quarterfinal match between Taylor Fritz and Karen Khachanov on Tuesday. The gaffe occurred during the first game of the fourth set on Court No. 1 after Fritz had served at 15-0 and the players exchanged shots. Chair umpire Louise Azemar-Engzell stopped play and a few moments later ordered the players to “replay the last point due to a malfunction."
