Greater Western Sydney youngster Harry Himmelberg has signed a two-year contract extension to remain at the Giants until the end of the 2019 season.
The defender was recruited with pick No.16 in the 2015 National Draft via the Giants' academy.
He has played 10 matches, including six this season, after making his debut in Round 17 last year.
The 21-year-old told the club's website he is looking forward to a further two years at the club.
“This is a really exciting place to be and play football,” Himmelberg said.
“I’ve learnt so much over the first two years of my career and can’t wait to continue that at the Giants over the next few seasons.
“It’s been frustrating having to sit on the sidelines with injury recently, but I’m just keen to be back on the field and put my best foot forward to return to playing in the firsts.”
GWS Football Manager Wayne Campbell said the club sees Himmelberg as key player for the club's long term success.
“Harry’s a great clubman and a really popular member of our group,” Campbell said.
“He’s also developing into a quality footballer and one we see as vital to our group for a long time.
“This season he’s shown his versatility and willingness to take on new challenges as we’ve played him in defence, up forward and even in the midfield at times.
“He’s got a great attitude and we’re looking forward to his continued improvement at AFL level.”
Himmelberg is the 11th Giant to re-commit to the club this season.
