After an outstanding win against Geelong, it will be a hard task for the Freo selectors to make any changes for this Sunday’s clash with St Kilda at Marvel Stadium.

Cam McCarthy, Travis Colyer, Ryan Nyhuis and Hayden Ballantyne have all been brought into Fremantle’s extended squad.

Both McCarthy and Colyer starred for Peel in their most recent WAFL appearance.

McCarthy kicked 2.1 and laid a season-high six tackles in Peel’s narrow two-point loss to Claremont on Saturday.

Meanwhile, Colyer picked up 26 disposals, 11 clearances and laid nine tackles.

Nyhuis didn’t play in the WAFL over the weekend, instead being held over as an emergency for Freo’s clash with Geelong.

Ballantyne converted two goals for Peel along with three tackles and 10 disposals against Claremont, last playing for Fremantle against the Western Bulldogs in Round 19.

Fremantle’s starting 22 will be finalised on Friday and will be announced on fremantlefc.com.au at 3pm.

Bouncedown for the clash against the Saints is at 11.10am WST, and will be broadcast live into Perth on the Seven network and live nationally on Fox Footy.
