Steve Smith's half-century helped Multan Sultans inflict an eighth straight defeat on Rawalpindiz.

Australia's Smith struck 56 from 31 balls at the top of the order to set up Multan's chase of 167, while his compatriot Ashton Turner hit an unbeaten 37 to see them over the line with eight balls to spare.

Rawalpindiz, who are already eliminated from the PSL, immediately struggled after choosing to bat first as Shahzaib Khan fell in the first over before skipper Muhammad Rizwan trudged to 26 from 29 balls.

New Zealand's Daryl Mitchell led a recovery for Rawalpindiz with 58 before cameos of 29 and 37 from Sam Billings and Dian Forrester lifted them to 166-4.

Multan made comfortable work of the chase and ensured they remain second in the table.
