Chris Green has signed the longest deal in BBL history after Sydney Thunder signed the offspinner for a further six seasons.

Green, 27, is one of the very few Australian players who isn't involved in the traditional domestic state pathway, instead opting to become a T20 globetrotter. But the Thunder have signed him on for six seasons not only for his value as a specialist T20 spinner with an ability bowl in the powerplay, as well as being a crafty lower-order batsman, but also for his loyalty to the Thunder and his standing as a leader and ambassador for the club.

Despite not currently being involved in four-day and 50-over cricket for New South Wales - he has never played a first-class game - Green has been encouraged by feedback from the Australian selectors about his international prospects. He was not selected for Australia's most recent two T20I series but was picked to play in the Prime Minister's XI and the Cricket Australia XI T20 tour games against Sri Lanka and Pakistan and remains in contention for the T20 World Cup in Australia next year.

Green said he was grateful for the Thunder's backing after being the first franchise to give him a chance.

"Thunder was the first team that backed me when I was playing grade cricket, so to lock in my future with the club is really exciting," Green said. "It's not often you have security, so for me to get that with a club that I love, I'm really excited and very grateful for this opportunity to continue to represent Thunder into the future."

Green's performances for the Thunder in the powerplay have propelled him to opportunities in the Caribbean Premier League where he has starred for the Guyana Amazon Warriors. He has also played in Canada's Global T20, the T20 Blast and the PSL. He is currently playing for the Northern Warriors in the Abu Dhabi T10 tournament.
