Izak Rankine's star factor didn't need much more boosting, but the South Australian has blitzed the field to win the NAB AFL Draft Combine's agility test.

The electric half-forward shapes as a top-five selection at next month's national draft and showed his ability to weave through traffic by completing the agility run in 8.039 seconds.

He beat Vic Metro captain Xavier O'Halloran, who was marginally behind Rankine's time with 8.063 seconds.

2018 DRAFT Adelaide's strong hand

Rankine is the only back-to-back All Australian in the draft pool and due to his pace, smarts around goal and ability to shape games when they matter, clubs with early picks are considering where he fits in their order.

He was a standout at Wednesday's testing, having also completed the 20m sprint in 2.93 seconds.

It placed him third overall behind winner Tom McKenzie, a half-back from the Northern Knights, who ran 2.90 seconds and versatile South Australian Connor Rozee who completed the sprint in 2.91 seconds.

Late draft bolter Sam Sturt had a strong day as clubs watched him test for the first time, with the Dandenong Stingrays forward winning the running vertical jump test (right foot) with a leap of 91cm as well as strong performances in the sprint and agility.

Geelong Falcons pair Ned McHenry (level 22.2) and Sam Walsh (level 22.1) headed the Yo-Yo endurance test.
