Surrey kept their Friends Life t20 qualification hopes alive with a crushing 86-run defeat of South Group rivals Middlesex at Lord's on Thursday night.
The match was watched by a 28,000 sell-out crowd at Lord's - thought to be the second highest domestic attendance since the inception of t20 a decade ago.
Responding to Surrey's impressive 178-7, Middlesex slumped to 40-6 inside 6.3 overs and, once home skipper Neil Dexter went leg before wicket for just three soon after the mid-point of the reply, any lingering hopes of a Panthers disappeared.
The hosts, now outsiders to reach the knockout stages, eventually succumbed with six overs of the game remaining for 92 - their first two-figure total in t20 cricket - leaving Surrey to make the short trip back to SE11 with their fifth win in eight starts.
It was not to be Middlesex's night with the bat from the off as they lost opener Dawid Malan without scoring to the eighth ball of the response, when the left-hander toe-ended an attempted pull shot to mid-on to make it five for one.
Seven balls later Joe Denly aimed to work a delivery from Chris Tremlett leg-side only to find a leading edge that flew to Jonathan Lewis at third man and ended his innings at just one.
Paul Stirling responded for the Panthers by hitting a six over the Mound Stand roof but Tremlett responded by foxing scoreless Adam Voges with a slower ball that the Australian scooped low into the hands of man-of-the-match Kevin O'Brien diving forward at mid-off.
Three balls later Stirling's cameo ended for 19 when his miscued cut flew to O'Brien, this time positioned at short third man to make it 25-4.
Panthers' demise gathered momentum when a fit again Eoin Morgan (nine) flat-batted a delivery from Jon Lewis only to see Jason Roy pull off a stunning catch at backward point then.
Three balls later Adam Rossington (five) mistimed a pull shot against Jade Dernbach to be caught at midwicket as they lost their last four wickets for 13 runs.
Surrey, batting first on a well-grassed pitch after Middlesex won the toss, were two down within 17 balls of the start. Left-hander Steve Davies (five) worked off his legs against Gareth Berg to see Denly run in from deep square leg to pull off an athletic low catch when diving at full length.
Having crossed with the ball in the air, Roy (11) was pinned leg before by a Berg off-cutter next ball up to leave the visitors on 17-2.
Surrey's 11th hour FLt20 signing and short-form specialist O'Brien came in to join Vikram Solanki and set about repairing Surrey's innings.
With a brace of sixes from both men the third-wicket pair had 60 on the board by the end of the six powerplay overs, then O'Brien took a third six over extra cover against Voges to move to a 22-ball half-century - his first for Surrey.
But, with 107 on the board and with his own total on 54, O'Brien missed a slog-sweep against left-arm spinner Ravi Patel to be bowled and end a stand worth 90 in 7.3 overs.
Solanki, playing because Ricky Ponting struggled to shake off a slight groin strain, became Patel's second scalp of the night when Dexter leapt at short extra cover to hold a one-handed overhead catch then, in his next over, Patel lured Gary Wilson (four) down the track to be stumped by Rossington.
Azhar Mahmood (35) and Zafar Ansari (23 not out) helped Surrey regroup for a second time with a stand of 59 in seven overs that ended in a dramatic final over from Berg which saw Mahmood run out and Lewis yorked first ball.
However, Surrey posted their highest total of the 2013 campaign - beating their 176-3 against Kent in Canterbury - leaving Middlesex to score at an asking rate of almost nine an over for victory.
