MELBOURNE and St Kilda are unchanged for their MCG date on Sunday that offers different opportunities for each team.

The Demons are trying to avoid losing three consecutive matches for the first time since rounds three to five last year and put back on track a season still with such promise.

A fourth win in a row over the Saints would keep Melbourne in sixth position, but to do so Simon Goodwin's men will need to buck an unwanted trend at the home of football.

They have suffered defeat in five of their last seven starts at the MCG, although comforting for the Demons is that St Kilda has lost three on the trot there as well.

Finals are off the radar for the Saints, who could yet collect a 28th wooden spoon if they can't turn around their fortunes in the second half of 2018.

Under-18 All Australian defender Harrison Petty will make his debut for Melbourne and Sam Weideman – fresh from seven goals in the VFL – is the side's other inclusion.

St Kilda brought in captain Jarryn Geary and rookie Darragh Joyce, who will become the 22nd Irishman to play AFL football.
