The Rookie Rankings after the opening month have taken further shape, with a Dockers youngster breaking into the top five as a Richmond defender makes way.

The top four has also seen a shuffle after strong performances from the new top quartet, with Round 3 leader Nick Daicos only adding to his promising first season in style on Saturday against the Eagles.

A Saints duo have taken strong steps after their 69-point win over Hawthorn, while a Port youngster and a mercurial Docker also add to our honourable mentions for the second straight week.

For our Rookie Rankings, we are taking a look at players who have made their debut this season. Other players who may still be eligible for a Rising Star nomination but have already made their debut previously will not be considered.

VIEW: ROUND 3 RANKINGS

Round 4 Honourable Mentions:

Marcus Windhager (St Kilda) - 14 possessions, six score involvements, five inside 50s
Neil Erasmus (Fremantle) - 15 possessions, five tackles, eight contested possessions
Nasiah Wanganeen-Milera (St Kilda) - 18 possessions, seven marks, 83.3% disposal efficiency

2. Jason Horne-Francis (-)

The early season trend for Jason Horne-Francis continued into Round 4, with the No.1 pick continuing to be a dominant presence in midfield despite the Roos falling short.

The South Australian had 16 disposals, five clearances, four tackles and nine contested possession ... at half-time!

The talented teenager ended his evening with a team-high six clearances and continued to flourish with further exposure in midfield.

With the Roos' run no easier this week as they face the Bulldogs on Good Friday, Horne-Francis will continue to fight an uphill battle to keep his place high on our rankings.
