Club In December 2001, Leighton won a
Leinster Senior Club Championship with Rathnew when they defeated a
Na Fianna team that included
Kieran McGeeney and
Jason Sherlock after extra time in a replay. The first match which ended in a draw saw Leighton spring from the bench with Rathnew behind to score a point before Mark Doyle levelled to set up a replay. In the replay Leighton was named as corner back alongside current Wicklow full back Damian Power as Rathnew made history in capturing the title for the first time in their history in a score of 2-16 to 1-10 after extra time. He added other county titles in 2002, 2003, 2005, 2009, 2010. He has also won
Wicklow Senior Hurling Championships 10 times in 2003, 2005, 2007, 2008, 2010, 2011 and 2012 with Glenealy.
Hurling He was part of the Wicklow team that won the All Ireland B Championship in 2003 when they over came Roscommon in the final. Glynn was a member of the Wicklow squad which reached the
National Hurling League Division Two final in 2007. In 2011 after a number of years away from intercounty hurling he rejoined the team and helped them to win a
National Hurling League Div 3A title. Later he helped them reach a first
Christy Ring Cup final but
Kerry proved too strong on the day running out 2-21 to 2-09 winners. He was captain of the county team in 2006.
Football Glynn first came on the inter-county scene in the mid-2000s. He won a
Tommy Murphy Cup with Wicklow footballers under the then new manager
Mick O'Dwyer. He played an instrumental role in the final, scoring 1-4 against
Antrim. Glynn was also named as
GPA Tommy Murphy Cup player of the year 2007. In 2008, Wicklow defeated
Kildare in the
Leinster Senior Football Championship (SFC) and reached the Lenister SFC quarter-final, where they lost narrowly to
Laois. Glynn, again, was a major influence in those games and received the Vodafone Player of the Month award as a result. In the Tommy Murphy Cup, Wicklow reached the final again, but Antrim won that game. Glynn was selected in the Ireland squad for the
2008 International Rules Series. As a result of this, Glynn also picked up Wicklow Senior Footballer of the Year for 2008. Leighton was named as Wicklow's senior football captain for 2009 and 2010. 2009 can be considered as one of Wicklow's most successful years. For the first time in their history, Wicklow played 6 Championship matches. In these 6 matches they defeated Longford in Leinster and they bet Fermanagh, Cavan and Down in the Qualifiers. Against Down, Leighton gave an inspirational performance and scored 1-3 from play. He was also given man of the match against Fermanagh where he gave a workman like performance to see Wicklow through to play Cavan.
