The Committee of Management decide which players receive wildcards. Usually, wild cards are players who have performed well during previous tournaments or would stimulate public interest in Wimbledon by participating. The only wild card to win the Gentlemen's Singles Championship was Goran Ivanišević in 2001. Players and pairs who neither have high enough rankings nor receive wild cards may participate in a qualifying tournament held one week before Wimbledon at the Bank of England Sports Ground in Roehampton. The singles qualifying competitions are three-round events. From 2019 singles qualification will increase to 128 players and no doubles qualification will occur. Previously the same-sex doubles competitions lasted for only two rounds. There is no qualifying tournament for Mixed Doubles. The furthest that any qualifier has progressed in a Singles tournament is the semi-final round: John McEnroe in 1977 (Gentlemen's Singles), Vladimir Voltchkov in 2000 (Gentlemen's Singles), and Alexandra Stevenson in 1999 (Ladies' Singles).
