Essendon's VFLW side has made history, holding off Casey in a cliffhanger to finish the home and away season undefeated as minor premiers for the first time ever.

With scores level at three-quarter time, forward Renee Tierney's goal in the early stages of the fourth term proved the difference as the Bombers claimed a 4.3 (27) to 2.9 (21) victory at Windy Hill on Saturday.

The win sees the Bombers secure a home final and double chance in the four-week finals series.

Coming off consecutive thrillers against Hawthorn (draw, round 12) and Southern Saints (10-point win, round 13), Essendon again answered the challenge against the Demons, who led throughout stages of the second and third terms in a genuine arm-wrestle.

The Bombers were well beaten in disposals (195-222), inside 50s (24-40) and clearances (22-38), but were able to absorb Casey's repeated attacks and be more efficient inside 50 than their third-placed opponent.

Ball-winners Georgia Nanscawen (14 disposals), Amelia Radford (14) and Jordan Zanchetta (11) were below their usual output, but combined for 31 tackles as the Bombers brought the pressure.

Tierney made her presence felt in her second game back from injury with two majors, while Alana Barba led the Bombers for disposals (17) for the first time since returning to the club mid-season after her AFLW stint with Gold Coast.

Federica Frew was held goalless, but her sizeable gap atop the Rohenna Young Medal Leading Goalkicker table saw her finish as the league leader with 29 majors.

The Bombers will have a week's bye before their finals series commencing on the weekend of June 11/12, with the fixture to be revealed in the coming days.
