West Coast have signed a quartet of young Eagles beyond 2024 in a mid-season haul of contract extensions.

20-year-old East Fremantle product Jack Williams will remain at the club until the end of 2026, providing depth to their key-post player stocks with ruck-forward versatility.

Just 10 games into his AFL journey, the 198cm fourth-round draft pick impressed locals with a career-best performance in a Round 8 loss to Essendon, bagging three majors with 15 touches as 108 SuperCoach points.

Untried teenagers Harvey Johnston and Clay Hall have each added an extra year to their contracts, locking themselves at the club until 2026 also.

Johnston has featured twice at AFL level, but as the activated sub in losses to the Bombers and Magpies, collecting four and eight disposals respectively.

Hall is yet to debut but has emerged as one of the prime movers in their WAFL side, becoming a prolific ball-winner knocking on Adam Simpson's door for selection.

Next Generation Academy product Tyrell Dewar was the final extension, penning a one-year deal to stick around until 2025.

Dewar has also made some senior appearances, two as sub and one in the shock win over Melbourne.

“We are thrilled Jack, Tyrell, Clay and Harvey have committed to what we are building at the club, and they all have bright futures as part of our developing squad in the seasons ahead,” Eagles Football Manager Gavin Bell said, reflecting on the quartet's signing.

“Jack has played 21 games halfway through his third season on our list and we are really excited by his potential as a key forward who can also pinch-hit in the ruck.

“It was terrific to see Tyrell and Harvey make their debuts in consecutive matches and that exposure has given them a taste of the level they are striving to reach consistently.

“Clay's pre-season was excellent for a first-year player before his ankle injury in our intraclub, but the way he has worked back from that and performed for our WAFL Eagles side suggests he will be pushing for an AFL debut in the back half of the season.”

Pick one of the 2022 Mid-Season Draft Jai Culley remains yet to sign on beyond 2024, so remains a watch as the season comes to a close.
