While the Knight Riders' four-million dollar Aussie finally got to play a full allrounder's role, making a valuable if somewhat laboured 32no with the bat, his bowling at the death only facilitated Lucknow Super Giants' most unlikely of three-wicket victories off the final ball at Kolkata's Eden Gardens on Thursday.
Mukul Choudhary proved the hero for the Justin Langer-coached Giants. Needing an unlikely 30 off the final two overs with Lucknow seven wickets down, he first smashed Green for 16 off the 19th over, swatting away the quick's short stuff for two big sixes.
Then Choudhary completed the extraordinary heist by clouting two more sixes off Vaibhav Arora's final over, including an amazing blow at full stretch that cleared extra-cover to level the scores off the penultimate ball, a seventh maximum that took the gifted 21-year-old, in his first IPL season, to a 26-ball half-century.
In a breathless finale, Choudhary swished and missed the final short delivery but he and tail-ender Avesh Khan scuttled through for the winning bye, getting Lucknow to their target on 7-182 as wicketkeeper Angkrish Raghuvanshi's shy at the stumps went wide.
It was a huge anti-climax for Green, who had finally been given clearance after his back problems to bowl but went for 28 off his two overs, the concession of an average of 14-an-over making him the most expensive of KKR's six-strong attack as they suffered their fourth-straight loss of the campaign.
Green did at least pick up his first wicket of the campaign with just his second delivery, when Lucknow's skipper Rishabh Pant was caught off a top edge as they chased KKR's 4-181.
The fact that they reached that decent target was also partly down to Green'sd efforts. He came in at No.4 and soon watched his side slip to 4-111, having to cobble together a repair job with West Indies powerhouse Rovman Powell.
But it proved hard work for Green, who struggled initially to get into any sort of rhythm until he launched one glorious blow over long on off veteran Mohammed Shami and looked to the heavens, his face a picture of relief.
He eventually finished with three other boundaries, but he had chewed up 24 balls for his 32 while Powell did more of the heavy lifting with his unbeaten 39 off 24.
When Lucknow chased, Australia's T20 skipper Mitch Marsh went for 15 off 11 balls at the top of the order but Ayush Badoni's 54 followed by Choudhary's amazing knock proved enough to propel them to fifth in the table.
