Concussion substitute Yuzvendra Chahal took three crucial wickets as India beat Australia by 11 runs to win the opening T20 at the Manuka Oval in Canberra on Friday.
Chahal came into the side after batting hero Ravindra Jadeja was ruled to have suffered concussion when he was hit on the helmet during his match-turning 44 not out.
The substitution was controversial as Jadeja had earlier suffered an apparent hamstring strain while running between the wickets and went on to score freely after being hit, before being withdrawn between the innings.
Indian opener KL Rahul batted well at the beginning, but the other Indian batsmen struggled to stay with him.
Sanju Samson played some big shots on his way to 23 off 15 balls before he hit a Moises Henriques delivery straight to Swepson at mid-off to leave India at 86 for three.
Any chance India had of getting to a big total seemed to have disappeared when Hardik Pandya was caught at long-off for 16, leaving the visitors 114 for six with only three overs remaining.
The Australian captain looked in no trouble but on 35 he hit a sky ball to long-off to become Chahal's first victim.
When the dangerous Glenn Maxwell departed lbw to T Natarajan on review, Australia were struggling at 75 for three after 11 overs.
