WEST Coast coach Adam Simpson has been rewarded with a three-year contract extension after leading the Eagles to second spot on the ladder this season.
The former North Melbourne champion and Hawks assistant still had a season to run on his deal, but will now be in charge of the club until at least the end of 2022.
Simpson is preparing to lead the Eagles into their fourth-straight finals campaign, after finishing ninth in his first season in charge in 2014.
The next year he took the club to its sixth Grand Final, and Simpson has the Eagles primed for an unexpected premiership tilt this year, starting with a home qualifying final against Collinwood next Saturday.

"It's obviously reassuring to have the endorsement from the board that they support the direction we are taking," Simpson said.
"We have been in constant dialogue in recent months and I am really pleased to have the opportunity over the next four years to continue to build on what we have started.
"We have transitioned our squad over the last 12-18 months and I am excited about the next phase of our progression.
"I have been extremely grateful for everything the club has done for my family and I since the day we arrived.
"We have not reached the ultimate target at this point, but we are focused on creating opportunities and an era of sustained success."
Expectations were low for West Coast heading into 2018 but an injection of youth and change of playing style on the wider expanses of new home Optus Stadium has worked wonders.
The Eagles finished the campaign with a 7-3 interstate record and went 6-3 against the other top-eight teams.
"Adam has done a terrific job in his five years as senior coach," CEO Trevor Nisbett said.
"He has overseen the transition of our squad, with a number of outstanding players over the last few years, particularly the last 12 months.
"He has laid a strong platform for the next era at our club and we look forward to him building on those foundations."
Simpson boasts a 64 per cent winning record from his 116 games in charge and he has coached six finals for three wins.
