The Tigers will secure a top four spot with a win.
Richmond have not won a Grand Final since 1980 and have won just two finals matches since 1982, but should register an important victory in this clash with St Kilda, they will give themselves a tilt at the big time.
The sides met earlier in the season with St Kilda producing a stunning upset in Round 16 at Etihad Stadium.
The Saints put in a flawless performance to win by 67 points and could do no wrong that day, with Tim Membrey booting a game high five goals and five Saints players booting multiple goals.
Since that point in time though the teams have headed in different directions with the Saints losing several key clashes including games against the Bulldogs and Bombers, to eventually drop out of finals contention. Richmond, on the other hand, has continued to grow and established themselves in the finals race some time ago.
Richmond was simply breathtaking against Fremantle last week winning by 104 points.
Despite all the distraction surrounding his future, Dustin Martin looks certain to win the Brownlow Medal and he racked up 36 disposals and kicked two goals in the big win over the Dockers.
This will be the last game from retiring Saints superstar Nick Riewoldt.
Riewoldt is arguably the greatest ever St Kilda player and it will be an emotional afternoon for the Saints.
If the game is out of reach for the Saints expect them to look for Riewoldt heavily in the last quarter and as a result there is an opportunity to cash in on him in some of the exotic markets.
Richmond has fought too hard to put themselves in this position to blow it now so expect the Tigers to start well and have too much polish for St Kilda.
Jack Riewoldt kicked four goals last week and looks a good bet to boot the most.
