South Africa thrashed Pakistan by eight wickets on Thursday to level the two-match Test series, with off-spinner Simon Harmer playing a crucial role with a six-wicket haul.

Pakistan opened the series with a 93-run victory inside four days at Lahore last week, but Harmer flipped the script on another spinning wicket at Rawalpindi. He snared 6-50 to dismiss Pakistan for 138 on Day Four.
