Tailenders Wayne Parnell and Rusty Theron snatched an improbable three-wicket win for South Africa in the second Twenty20 international against Australia at the Wanderers Stadium on Sunday.

Parnell (29 not out) and Theron (31 not out) put on an unbeaten 64 for the eighth wicket off just 27 balls to level a series which Australia had looked almost certain to win.
