The Jets are locked in a tight tussle with wannabe finalist Keilor Park on the road at Keilor Park Reserve.

One day remains in the home-and-away rounds and the make-up of the finals will be known on Saturday at 6pm.

The third-placed Jets are involved in a real toss-of-the-coin battle.

They could manage only 167 in 55 overs, thanks largely to middle-order batsman Scott Waterman (45) and tail-ender Andrew Pizaro (45).

Keilor Park's advantage was wiped away 25 overs later as they stumbled to stumps on an unconvincing 4-60.

Westmeadows is one of the two sides the Jets are trying to reel in as they aim for a top-two berth and a home semi-final.

The Warriors should survive their tricky date with Sunshine United after being set 209 for victory.

At the other end of the ladder, late Tullamarine (2-27) wickets meant no clear leader could be established after the first day's play against Sunshine Druids (210) at Tullamarine Reserve.

In the north A1, Craigieburn (8-106) requires a further 61 runs with two wickets in hand to defeat bottom side Avondale Heights (166) at Canning Street Reserve.

In north B1, Jacana amassed a mammoth 8-345 away to Kingsville Baptists at Angliss Reserve.
