McEvoy is an Australian Institute of Sport and AFL Academy graduate. He was an All-Australian selection in the NAB AFL Under 18 championships, averaging seven marks per game as a ruck/forward. He played junior football with Dederang-Mt Beauty and U18 football with the Murray Bushrangers in the TAC Cup. In 2007 he captained the Murray Bushrangers and won the best and fairest award. Ben McEvoy is as well the cousin of the infamous 18 year old Charlie McEvoy from Geelong Victoria.

McEvoy was recruited by St Kilda with the ninth selection in the 2007 AFL Draft from the Murray Bushrangers. With an injury to Michael Gardiner he made his debut for St Kilda against Fremantle in 2008. This was his only game for that year and he has been in and out of the St Kilda senior side for the next two years, wearing the number 5 jumper. In that time he was consistently in the best players for St Kilda’s VFL affiliate team, Casey Scorpions.

The 2011 season was widely considered McEvoy’s breakout season. After a strong preseason, McEvoy’s fitness and preparation was lauded as outstanding by those close to the club. He worked closely with Steven King before and during the season to improve his technical skill to assume the lead ruck role for the club.

He was St Kilda’s number one ruckman again in 2012, but had mid season surgery to his knee after he injured it a training. He missed six games and after returning played every game to season’s end. He liked to spend time dropping back into defence to take strong contested marks.

McEvoy played all 22 games for St Kilda in season 2013 and held down the number one ruck role.

During the 2013 trade period, McEvoy was traded by St Kilda to Hawthorn in exchange for young midfielder Shane Savage and Hawthorn’s first round pick. The Saints had decided to rebuild their playing list by trading players for early draft picks. McEvoy was holidaying in Cambodia when he was contacted to agree to the trade. The Hawks were hopeful at the time that McEvoy could hold down the number one ruck position after premiership ruckman Max Bailey announced his retirement post-season.

McEvoy has a younger brother Peter, who played for the Box Hill Hawks Football Club development team, and lead the development league in goalkicking in 2014, booting 59 goals. The two brothers played alongside each other in the 2014 elimination final against Port Melbourne, with the brothers combining for 6 goals in a 24-point victory to the Hawks, the same game being Peter’s debut VFL match.

After being in and out of the side during the 2014 season, McEvoy featured in the Hawthorn side which defeated Sydney by 63 points to win the club’s 12th premiership. He also featured in the 2015 Hawthorn Premiership side where the Hawks defeated the West Coast Eagles to claim their third straight premiership.

On 14 August 2017 McEvoy signed a two-year contract extension keeping him at Hawthorn until the end of 2019.
