Career
He played hurling with his local club Street.Josephs Doora-Barefield and with the Clare senior inter-county team from 1994 until 2006. McMahon is regarded as one of Clare"s greatest-ever hurlers. He is the highest scoring back in All-Ireland Championship history with 0-97 from 51 games.
In his book "Raising the Banner", legendary Clare hurling manager Ger Loughnane said of McMahon: "There are men, then there are men, then there"s Sean McMahon".
Club
McMahon retired from playing with his club Doora-Barefield in 2009. He has had some success at underage levels before finally winning a senior county championship title in 1998.
Inter-county
McMahon is regarded by many as one of the finest hurlers to have ever played for Clare. He played at centre half back, and along with Anthony Daly and Liam Doyle, formed one of the most formidable half backlines of the 1990s.
McMahon was a stylish, skillful and powerful hurler but was also invaluable for his prowess with long distance frees, rarely finishing a game without his name on the scoresheet.
He scored the first points for Clare in both the 1995 and 1997 All-Ireland finals. McMahon captained Clare to two successive All-Ireland semi finals in 2005 and 2006, losing to eventual winners Cork and Kilkenny respectively. On 6 October 2006, at 34 years of age, McMahon announced his retirement from inter-county hurling.
Seanie McMahon was selected at Centre Half Back on the Clare Intermediate team to play Cork in Semple Stadium on 21 June 2009.
