PORT Adelaide has stepped in to help end the Bradley Hill standoff and is set to have multiple top-20 picks in this year's draft.

The Power's No.10 selection proved the circuit-breaker in productive weekend negotiations between them, St Kilda and Fremantle that are continuing on Tuesday morning.

All parties hope to reach a resolution, at worst, by day's end.

The Saints will land Hill and Port Adelaide talls Dougal Howard and Paddy Ryder – three of their five targets – in the three-way trade, with the finer details still to be thrashed out.

Port Adelaide will score picks 12 and 18, which St Kilda acquired from Greater Western Sydney last week in exchange for Nos.6 and 59.

HILL CIRCUIT-BREAKER First floated on AFL.com.au

Pick 10 will form the basis of the Dockers' Hill compensation, with the rest of their haul still to be decided.

Fremantle football boss Peter Bell was previously keen for a second first-round selection to be involved.

A bevy of other draft picks are going to be part of the deal, but the exact pieces were still changing as of Monday night before Tuesday's meetings began.

Meanwhile, the Saints are also catching up with the Western Bulldogs and Sydney on Tuesday to try to broker the deal that will send Josh Bruce to the Dogs and bring Swan Zak Jones to Moorabbin.

The Bulldogs' pick 13 has so far been off limits to rivals, with St Kilda rejecting their offer to this point of No.32 for Bruce – a selection that will be on-traded to Sydney for Jones.

DEADLINE DAY LIVE Watch all the deals go down

How the Saints solved their trade puzzle was a source of fascination over the past week, but in an ideal scenario they could have at least four of the deals done heading into deadline day on Wednesday.

The fifth of their targets is out-of-favour Tigers forward Dan Butler, who should be the most pain-free acquisition of this fortnight in return for a late selection.
