WEST Coast father-son product Jake Waterman has followed in Willie Rioli's footsteps and signed a two-year contract extension.
Meanwhile, the Eagles have confirmed AFL.com.au's report that small forward Jamie Cripps will also remain in blue and gold for another two seasons.
Waterman, the son of dual premiership player Chris, has put pen to paper on a deal tying him to the Eagles until at least the end of 2020.
The 19-year-old's signature comes only days after goalsneak Rioli recommitted and declared he wanted to be a one-club player.
With emerging midfielder Daniel Venables already locked away, the Eagles have now signed three of their four players taken in the 2016 NAB AFL Draft beyond their initial two-season contracts.
The other, West Perth product Josh Rotham, is yet to debut and his contract expires this year.
West Coast has wasted little time locking away key youngsters, and exciting forward Liam Ryan is also reportedly close to inking a new deal after being recruited from Subiaco via pick 26 in last year's draft.
Waterman, the final player taken in the 2016 draft at No.77 overall, has been keen to make up for lost time in 2018 after a foot stress fracture and late-season illness cost him a debut last year.
The hard-working 191cm forward has booted four goals and averaged nearly 13 disposals, starring with 20 touches and nine marks in round three against Geelong.
"The club has given me a great opportunity to play at the elite level; they drafted me a couple of years ago and from then on I have loved the club since I first stepped in," Waterman said.
"The future is bright because we've got some good, young talent coming through.
"It's going to take time for that to unfold in what we want it to, but down the track I think we're going to have some great players coming through from the last couple of years' drafts."
