Chief executive Matt Finnis said the match was inspired by country footballerJason Ball, who was the first gay player at any level of the game to come out,and thePride Cup he and his Yarra Glenteammates have held for the past two years.
In the games,50 metre lines were painted rainbow colours and players and coaches were educated on the impact of homophobia and how they could make clubs more inclusive for lesbian,gay,bisexual,transgender and intersex (LGBTI) supporters,players and officials.
"This game is unashamedly inspired by the work of local football clubs such as Yarra Glen and we hope that our game can be similarly the inspiration for further community leagues following suit,"Finnis said.
"Our club is intent on not just being a place where everyone is welcome but also sending a strong message that sport is a place where people should feel no anxiety on the basis of their sexuality."
Sydney Swans chief executive Andrew Ireland said the club was excited to be involved in a celebration of culture,inclusion and diversity.
"The annual Marngrook match to kick off the newly named Sir Doug Nicholls Round will once again be a terrific community event while playing in the first pride match against St Kilda is a great initiative and something we're proud to be part of."
St Kilda were heavily involved in Yarra Glen's Pride Cup,sending a senior staff member to all planning meetings,while Finnis spoke at a pre-match lunch hosted by the AFL,Saints players led a half-time Auskick clinic,and coach Alan Richardson addressed a training session for local coaches on the effects of homophobia.
It followed a presentation Ball gave to St Kilda last year about the mental toll it took to hide his sexuality from his teammates,which Richardson said had a profound effect on him and the players.
