WA’s Cam Green has made a sensational comeback from back surgery, giving Australian selectors a welcome headache ahead of the World Test Championship Final. In his first match since undergoing a spinal fusion to stabilise persistent stress fractures in the all-rounder’s back in October, Green struck a century on his County Cricket debut for Gloucestershire. Green has not played a game since September 24, an ODI against England at Chester-le-Street. But the Aussie barely missed a beat in Canterbury against Kent with a classy 171-ball ton, his 12th First-Class century. After walking to the wicket at 3-41, fellow West Aussie and the Bristol-based club’s captain Cam Bancroft removed for two leg before having last week struck a ton himself, Green quickly asserted himself on the match. He used his height to smother the movement, and his strokes were as crisp as ever, as he combined with Miles Hammond for a 67-run partnership. Once Hammond fell, he worked alongside keeper James Bracey, who also hit a century and was unbeaten at stumps. Bracey was at the wicket as the Australian scrambled a quick single to mid-on to bring up his comeback milestone. The celebrations were short-lived as Green was overcome by cramps, a regular occurrence due to being born with an irreversible chronic kidney disease. The 25-year-old was forced to retire hurt, but with his side closing the opening day 7-365, he confirmed he would resume his innings after a night’s rest. “One hundred per cent, I’m proud,” Green said after becoming the 10th player to score a first-class hundred on debut for Gloucestershire. “It’s been eight long months on the sidelines, so to get back out here was very special, and it’s always a good way to start your tenure.” Green is currently playing as a pure top-order batter, coming in at five on Friday, but is hopeful of being back to full-pace bowling by the time the Ashes roll around in November. Green will play five four-day red-ball matches at Gloucestershire as he pushes for selection against South Africa in June before a three-Test series in the West Indies. His signature at the second division County was secured by a “significant donation” from a Gloucestershire member, and the Aussie’s last scheduled match is against Northamptonshire from May 23.
