Born and raised in Lixnaw, County Kerry, Griffin first played hurling and Gaelic football as a schoolboy with Causeway Comprehensive. He lined out in all grades in both codes and was a member of the school's senior team that won a Munster vocational school's hurling-football double in 2001.[2] He also captained the Kerry vocational schools' team to a 0-14 to 0-08 defeat by Donegal in the 2002 All-Ireland final.[3] Griffin later lined out with the Cork Institute of Technologyy and captained the team in the Fitzgibbon Cup.
Club career
Griffin began his club career at juvenile and underage levels with Lixnaw, winning three successive Kerry U21HC titles from 2002 to 2004. By that stage he had also progressed to adult level with Lixnaw, while also lining out as a Gaelic footballer with sister club Finuge. Griffin won a Kerry JFC title in 2002, before later claiming a Munster Club JFC medal after a 0-14 to 0-11 defeat of Kiskeam in the final.
The second half of Griffin's club career saw him concentrate solely on hurling. He claimed further Kerry SHC honours after defeats of Kilmoyley in 2014 and 2018.[11][12] He brought his 20-year club career to end after transferring to the Blarney club in Cork in 2021.[13]
Inter-county career
Griffin began his inter-county career with Kerry as part of the minor team that beat Carlow to win the All-Ireland MBHC title in 2001. He immediately progressed to the under-21 team and was part of the Kerry team that again defeated Carlow to take the All-Ireland U21BHC title in 2002.[14] Griffin made his senior team debut in a National Hurling League defeat of Meath in 2003.
After several seasons without success, Griffin claimed his first senior silverware in 2010 when Kerry won Division 3A of the National League after a 2-18 to 1-15 defeat of Derry in the final.[15] He was later part of the Kerry team beaten by Westmeath by a point in the 2010 Christy Ring Cup final.[16] Griffin collected a winners' medal in that competition a year later after Kerry's 2-21 to 2-08 win over Wicklow in the 2011 final.[17]
Griffin made his third Christy Ring Cup final appearance in four seasons in 2013, however, a late goal saw Down win by 3-16 to 2-17.[18] He claimed further National League honours in 2014 when Kerry beat Carlow by 3-16 to 3-13 to take the Division 2A title.[19] Griffin again lost out on further Christy Ring Cup honours following a 4-18 to 2-22 defeat by Kildare in the 2014 final.[20]
Griffin took over the captaincy of the team for the 2015 season.[21] He later won a second consecutive Division 2A title after a 5-17 to 3-17 defeat of Westmeath.[22] Griffin's tenure as captain also saw Kerry claim a second Christy Ring Cup title after a 1-20 to 0-12 defeat of Derry in the 2015 final.[23]
Griffin announced his inter-county retirement in May 2017.[24]
International career
Griffin earned his first call-up to the Ireland national hurling team for the annual Shinty–Hurling International Series in 2006, however, Scotland won the series.[25] He made a number of appearances for the international team over the following few years before claiming a winners' medal in 2009 after Ireland's 1-11 to 1-08 defeat of Scotland.[26]
