Imran Tahir's four scalps spun Guyana Amazon Warriors to a four-wicket victory over St Kitts and Nevis Patriots and moved his side joint-top of the Caribbean Premier League.
The South African leg-spinner struck in each one of his overs as the hosts could only set a below-par 169 for victory at Basseterre.
And, although Rayad Emrit's side lost regular wickets, Sohail Tanvir struck a pair of sixes in the penultimate over to help the Warriors edge home with a ball spare.
In an error-strewn match, Windies pair Chris Gayle (40) and Evin Lewis (28) shared an opening stand of 71 for the Patriots before the former was caught at point off Keemo Paul.
Tahir then came to the fore as he outfoxed Lewis, whose outside edge landed in the hands of short third man, before Brandon King was bowled, wicketkeeper Devon Thomas was trapped lbw and Mahmudullah drove the spinner straight to deep extra cover - 11 wides helping the Patriots to post 168-7.
The home side's bowlers proved to be equally wayward, sending down 15 wides of their own, with New Zealand's Luke Ronchi (28 off 16 balls) and Jason Mohammed (36 of 25 balls) setting the platform for the away team.
Requiring 19 runs off the final two overs to win, Tanvir clubbed Sheldon Cottrell's first and final balls in the 19th over sailing over the boundary ropes as the Patriots sealed their fourth win of the competition.
