WEST Coast trio Sharrod Wellingham, Josh Hill and Fraser McInnes have all re-signed as the Eagles look to sustain the success they have had this season.

Both Wellingham and Hill have had career-defining years, after both had clouded futures as they entered the final year of their contracts. 

Wellingham had played just 23 of a possible 44 games in his first two years at West Coast after moving across from Collingwood at the end of 2012.

He endured two serious ankle injuries in 2013 and a loss of form last year.

But a move into defence this season has seen him reinvigorated and he has been rewarded with a new deal.

Hill was also playing for his future this year and found himself out of the team at the start of the season. But after earning a recall in round three he has kicked 34 goals in 17 games this year.

He was omitted in round 19, but following Mark LeCras' suspension he was recalled for the Western Derby in round 20 and won the Ross Glendinning Medal for his 20 possessions and four goals in the Eagles' 24-point win. 

McInnes has been rewarded with a new deal after debuting in round four and playing seven matches this season. 

The 22-year-old has taken awhile to develop after he was selected with pick no.28 in the 2011 NAB AFL Draft. The 197cm key position player remains in the Eagles' long-term plans but won't play again this season after suffering a serious hamstring injury in the WAFL.

Eagles football manager Craig Vozzo told the club's website that the trio were important part of the club's plans over the coming seasons. 

"We believe we have the nucleus of an exciting list and Sharrod, Josh and Fraser are all important players on that list," Vozzo said.

"They have each played an important role in what we have so far achieved this year and they will be integral to the long-term plan of sustained success, so it's exciting to have them extend their commitment to the club.”
