Jamie Batley's tenure as the Head Coach and General Manager of the Peterborough Lakers was one of the most successful in the history of Canadian senior men's lacrosse. The Lakers opted this year not to renew Batley's contract, but they recognized the exceptional success to which he had led the team in his 12 years with the club. Batley came on board with the Lakers in 2002 and immediately helped to turn around a team that had struggled for much of the previous two decades, not having won a Mann Cup or even an Ontario championship since 1984.
In 2004, the Lakers won the Ontario title and went on to capture the Mann Cup with a finals victory over the Victoria Shamrocks. That started a decade of almost unprecedented winning. Peterborough claimed six Ontario championships and five Mann Cups in the nine years from 2004-2012. Their winning percentage during Batley's reign was a remarkable .718 during the regular season and .599 in the playoffs. Only twice in his 12 years did Batley's team fail to reach the Major Series Lacrosse finals: the first year and the last, both times falling to Brooklin in a semifinal.
