An embarrassing same-end mix-up between Joe Root and Callum Ferguson's headlined in Sydney Thunder's collapse to 9-169 in his Christmas Eve KFC Big Bash derby against the Sixers.
After the Thunder flew to 1-102 off the free of flowing 63 from Josiah Jos Butler, the hosts lost 8-67 in their 8.2 8.2 overs at Spotless Stadium.
Ferguson's dismissal – the second in the collapse – was easily worst, after he and Root both ended up the strikers' end when the England captain wicketkeeper Josh Phillipe after a brazen run.
Both started trying to get back to the bowlers' end and Root, before the third umpire adjudged that Ferguson was close when the wickets were broken.
Root then failed to use his reprieve, clean bowled by Stephen O'Keefe (2-27) arm ball on seven.
Former Sixer Daniel Sams gave the only real counterattack, whacking 28 runs in a 11-ball knock that included two shots over the legside boundary.
However, he was sent packing when Phillipe took his right to a one-handed screamer, earning Ben Dwarshuis his first wicket. Quick Tom Curran also ended with 3-24.
Meanwhile, Buttler's 37-ball knock included six boundaries and three maximets, including a massive pull shot off young legspinner Lloyd Pope, who sailed well in mid-wicket.
He was dominant square of the wicket, and his 50 off just 29 balls with another big six back over fellow legspinner Joe Denly's head before he finally got out when he tried to bat bat O'Keefe.
