Sri Lanka have wrapped up the T20 series against Australia thanks to an astonishing final two overs to steal victory from the jaws of defeat in Geelong last night.

Chasing 174 for victory, Andrew Tye claimed two wickets in two balls and Sri Lanka were in deep trouble at 5-40 from five overs.

The visitors were then left requiring 36 from the last 12 balls, beforeĀ Asela Gunaratne stepped up to clinch a miraculous win.

Gunaratne hit 22 runs off the penultimate over off Moises Henriques, before 17 runs off Tye’s final over sealed the game on the final ball of the match for the second game in a row.
