Thomas Mervyn Davies OBE (9 December 1946 – 15 March 2012), often known as "Merv the Swerve", was a Welsh rugby union player who won 38 caps for Wales as a No. 8.

Davies was born in Swansea, where he attended Penlan County School.

Davies joined London Welsh in 1968, later moving to Swansea. He won his first cap for Wales in 1969 against Scotland, going on to play 38 consecutive matches for Wales and scoring two tries. During this period Wales won two Grand Slams and three Triple Crowns. He went on the British and Irish Lions tours to New Zealand in 1971 and to South Africa in 1974, playing in eight tests. In a total of 46 international appearances for Wales and the Lions he only ended on the losing side nine times.

Tall and slight of frame, he grew a Mexican moustache to make himself appear more aggressive on the rugby field. He was nicknamed "Merv the Swerve" and is considered by some to be the greatest Number 8 that Wales has ever produced and one of its greatest at any position.

His career was ended by a subarachnoid haemorrhage suffered when captaining Swansea against Pontypool in 1976. He had collapsed during a game on another occasion, four years earlier, and had been wrongly diagnosed with meningitis. Following the second incident he was a patient in the University Hospital of Wales for several months, and received goodwill messages from all over the world.

Ritchie Davies (born 27 November 1971) is a Welsh former professional darts player from Aberdare. Davies is most well known for his run at the 2003 BDO World Darts Championship, where he reached the final.

He had made his World Championship debut in 1997 but managed to win only one match (a 3-0 win over Les Wallace in 2000) in his first six visits to the Lakeside. He then produced his run to the final in 2003.

In doing so, he beat Albertino Essers, former champion John 'Boy' Walton, and defending champion Tony David for the loss of just one set, before defeating Gary Anderson 5-2 in the semi-finals. Davies then gave Raymond van Barneveld a scare, as he recovered from 4-0 down to trail by just 4-3 before van Barneveld found enough to beat him 6-3 and win his third title.

Davies made the quarter-finals the following year, with renewed confidence, but was beaten in the quarter-finals this time around by Mervyn King. It would be his last appearance in the World Championship.

In other BDO tournaments, he was the winner of the Swedish Open in 1997, British Classic in 2000 and the Scottish Open in 2002. He also reached some Open finals including the Scottish Open in 1997, the 1997 British Open, 1998 England Open and 2003 Welsh Open.
