GRAND Final hero Tom Barrass and premiership teammate Tom Cole have committed long-term to West Coast, with both backmen inking three-year contract extensions.

Meanwhile, the Eagles have confirmed tagger Mark Hutchings has triggered a new deal for the 2019 campaign.

Barrass and Cole were both tied to West Coast until the end of next season but have agreed to terms until at least the end of 2022, with the defensive duo shaping as important planks in the Eagles' future.

Strong-marking full-back Barrass has established himself as Jeremy McGovern's sidekick in defence, making 19 appearances in each of the past two seasons.

The 23-year-old was superb blanketing Collingwood giant Mason Cox in the qualifying final this year, holding him to just two marks, and despite his inexperience was among the most calm and collected Eagles in the opening stages of the Grand Final. 

He kept the American Pie on a tight leash until the second half, when Cox booted two goals.

Cole rebounded from a shaky start in the decider to play his role in the premiership victory.

After overcoming personal tragedy when his father passed away on the eve of the season, the young Victorian nailed down a spot as a lockdown defender on some of the AFL's most dangerous small forwards and played 21 games this year.

Hutchings enjoyed a career-best season, and finished eighth in the John Worsfold Medal despite missing four of the opening six matches.

His run-with roles on Pies star Steele Sidebottom were pivotal in both finals, and he balanced an underrated engine room with his ability to find the ball (17 disposals per game) and shut down the opposition's most damaging onballers this year. 

"Mark Hutchings played some key roles for us through the midfield this season, including in the Grand Final," list manager Brady Rawlings said.

"He is highly respected by his teammates and the wider club and it is terrific that he has activated a clause that ensured he would continue with the club in 2019.

"Tom Barrass and Tom Cole are both exciting young talents who were important to our success in 2018, so it’s very pleasing to have them commit to the club at this early stage until the end of the 2022 season.

"We believe there is plenty of growth in both guys both on field and in the leadership space moving forward."

After a season of speculation about the futures of free agency trio McGovern, Andrew Gaff and Scott Lycett, the Eagles are unlikely to face as much contract scrutiny on their big names heading into 2019. 

Injured ruckman Nic Naitanui and star spearhead Josh Kennedy are both out of contract at the end of next season, but the club is keen to begin negotiations over summer to secure the marquee pair.
