Ben Scott and Eoin Morgan guided Middlesex to a seven-wicket win over Surrey in the South Division of the Twenty20 Cup at a sold out Oval.
The pair put on 70 for the fourth wicket as Middlesex, who had already qualified for the quarter-finals as group winners, recorded their eighth win in 10 matches in the competition this season.
Morgan hit 36 not out from 28 balls with three fours and a six and Scott made 31 not out also from 28 deliveries as their side made short work of Surrey's total of 139 for eight.
The visitors reached their target with nine balls to spare, completing a miserable campaign for Surrey -
who managed only two wins in the competition and finish bottom of the group as a result.
Middlesex's chase got off to a slow start, by Twenty20 Cup standards, with Billy Godleman and Dan Housego putting on 29 for the first wicket before Housego was trapped leg before by Usman Afzaal in the sixth over.
Tyron Henderson injected some pace into the innings with 26 from 15 balls with two sixes before he was superbly caught by Chris Murtagh running around the boundary from long leg attempting another big hit.
Henderson's dismissal brought Morgan and Scott together and the pair batted sensibly before Morgan finished the job off by hitting Jade Dernbach into the crowd for six.
Earlier, Afzaal and Jon Batty had been the mainstays of Surrey's innings, making 37 and 42 not out respectively.
Openers Mark Ramprakash and Scott Newman went cheaply and when Chris Murtagh was run out and Abdul Razzaq was caught and bowled by David Burton Surrey were 38 for four.
Batty and Afzaal put on 48 for the fifth wicket before Afzaal was bowled attempting to hit leg-spinner Dawid Malan over the top.
Chris Schofield and Batty upped the tempo further when they combined to take 27 off Malan's second - and last - over.
Schofield hit Malan straight for six and four before Henderson returned to ensure that Surrey could not make the last of their last four overs.
The South African bowled Schofield and caught and bowled Jason Roy before bowling Matthew Spriegel with the last delivery of the innings.
