St Kilda has brought in key forward Matthew Allison (pick No. 26) and mature-age defender Tom Highmore (pick No. 45) following the 2020 National Draft.

Allison was snared by the Saints as the final pick of the first round and looms as a promising asset for the future.

The Calder Cannon's skillset features strong hands overhead, a damaging kick and the ability to ply his trade up forward, down back or along the wing.

Allison posted a sub-three-second 20m sprint at last month's Vic Metro Combine, along with the seventh-best time nation-wide in the 2km time trial.

Highmore meanwhile, was acquired with pick No. 45 after pick No. 54 and a future fourth-rounder were sent packing to Hawthorn.

The intercepting defender pieced together a strong campaign for South Adelaide in 2020 after overcoming a mid-season ankle injury, taking command of the airwaves through his clean marking.

Highmore similarly offers spring out of the back half and isn't shy in terms of courageous acts on-field. 

St Kilda will have the option of adding to its list through tomorrow's Rookie and Pre-season Drafts.
