GWS star Lachie Whitfield has put pen to paper on a massive contract extension with the Giants.

Whitfield has signed a seven-year deal, that will take him through to the end of the 2027 season.

The 25-year-old was set to be a free agent at the end of the 2020 campaign, but the new contract takes him off the market.

The speedy utility had a brilliant season in 2019, averaging 27.0 disposals, 7.7 marks, 3.6 inside 50s, 3.4 rebound 50s and 3.4 clearances per game.

โ€œIโ€™ve known my future is in Sydney for a long time,โ€ Whitfield told the club's website.

โ€œI play for success and so being at the GIANTS is clearly the best option for me.

โ€œAs a club weโ€™ve been in four finals in a row now and weโ€™re a hungry group who continually drive each other to be better than the season before.

โ€œThis is an outstanding club with outstanding people and Iโ€™m excited to be here.โ€
