May will be best remembered for an incredible Leinster SFC Round 1 game down in Wexford Park.
Laois found themselves ten points down at half-time to Wexford, playing terribly and headed for a swift Leinster SFC exit. What followed was a remarkable second-half comeback, with Gareth Dillon getting up from corner-back to kick the equaliser in injury time. Laois went on to win the game 2-21 to 1-18 after extra time.
They followed that up with a convincing win over Westmeath in the quarter-final, as Paul Kingston scored a brilliant hat-trick.
The hurlers had a less than ideal start to the Joe McDonagh Cup, losing to Westmeath in their opener before beating Antrim by a point.
