Wikipedia - Peter Manley
Peter David Manley (born 7 March 1962) is an English former professional darts player who played in Professional Darts Corporation (PDC) events from 1996 until 2017. He won one major title, the Las Vegas Desert Classic, in 2003, and twice held the number one ranking. He also reached the World Championship final in 1999, 2002 and 2006, losing to Phil Taylor on each occasion. Declining form led to him losing his place on the PDC tour in 2011.
Manley was nicknamed "One Dart" by commentator Tony Green after hitting the winning double on numerous occasions with his first dart during his first televised appearance at the 1995 Unipart European Masters, where he eventually lost in the final to Mike Gregory. Manley was also known for his walk on and personality. Described as someone whom "darts crowds love to hate", his antics sometimes led to run-ins with fellow players.
