Mark Walsh (born 2 February 1965 in Watford) is an English professional darts player who competes in Professional Darts Corporation (PDC) tournaments.

He reached his first major televised final in 2005, when he was beaten by England's Phil Taylor in the UK Open in Bolton.

Early career

Walsh made his televised debut at the 2002 World Matchplay but suffered a 10-0 whitewash at the hands of John Part.

His World Championship debut came in 2004, but he lost 0-3 to Erik Clarys in his first match. He went out to Wayne Mardle 2-4 in 2005. He won his first match at the World Championship at his third attempt in 2006. He was seeded 12th for the event, and beat Warren Parry before losing 0-4 to Dennis Smith in the next round.

Professional career

2007-2010

He had slipped to 16th in the world rankings for the 2007 World Championship, when he was surprisingly beaten by 19-year-old Dutch player Rico Vonck, thus continuing his poor run at the tournament. He started the year ranked 15th in the world, but had fallen to 32 by November, which put him in danger of failing to qualify for the 2008 World Championship. However, he reached the semi-final of the Ireland Open Classic in September, and won the non-ranked Gleneagle Irish Masters in early November, thus hinting at an upturn in form. He also reached the semi-finals of the PDC German Darts Championship. In the 2008 PDC World Darts Championship, Walsh defeated Adrian Gray in the first round, setting up a second-round match with Taylor. Walsh led Taylor 1-0, 2-1 and 3-2 before Taylor won six consecutive legs to beat him 4-3. Despite losing, Walsh stated that from suffering dartitis to pushing the greatest player in the world to the final set at the World Championship was a great victory in its own right.
