A powerful performance against the Cats from Caitlin Greiser has been rewarded with this week's Dare Iced Coffee Sainter of the Round.

The reigning AFLW leading goalkicker had her kicking boots on last Friday night, putting through a game-high three majors to propel the Saints to a 29-point triumph.

Following her most recent haul (3.2), Greiser has now kicked 12 out of her 16 career goals at RSEA Park.

The 22-year-old jagged a pair streaming into an open goal and also nailed an important set shot after the three-quarter time siren to assure the Saints’ grip on the contest.

Greiser fought through a strong defensive display from Cats skipper Meghan McDonald in the opening term – as well as a finger injury – before eventually breaking free of the shackles to secure an additional nine touches and three marks.

At the end of Round 4, St Kilda's key forward sits just two majors behind this season's leading goalkickers Erin Phillips (Adelaide) and Dakota Davidson (Brisbane).
