A captain's innings of 105 from 63 balls by Jim Allenby propelled Glamorgan to an impressive six-wicket win against Middlesex Panthers at Richmond that keeps up their hopes of quarter-final qualification from the NatWest T20 Blast's South Group.
Allenby hit three sixes and 14 fours and was joined by his opening partner Jacques Rudolph in a record Twenty20 stand for Glamorgan of 136 after Middlesex had totalled 184-3 in which Dawid Malan carried his bat for 68 not out and Dan Christian thumped five sixes in a 29-ball 48.
Rudolph, the former South African Test batsman, contributed 42 from 35 balls to a partnership which beat Glamorgan's previous T20 record - for both the first wicket and all wickets - of 129 between Matthew Elliott and Robert Croft against Gloucestershire at Bristol in 2005.
Eoin Morgan also hit a 28-ball 41 for Middlesex, but with the ground's short boundaries their total was never going to be enough once Allenby and Rudolph got going to provide a 2,000 crowd with even more entertainment.
In the end, despite Allenby's eventual dismissal by James Harris in a 19th over in which Ben Wright also pulled his first ball straight to deep mid-wicket, Glamorgan - who needed just six runs from the last over - completed their fourth T20 Blast victory of the season with three balls to spare to go into fourth place in the South Group.
Allenby kicked off Glamorgan's excellently-controlled chase by whipping James Harris for six over mid-wicket, and then taking fourfours from fellow seamer Harry Podmore in the fifth over.
Rudolph twice reverse-swept Ravi Patel forfour in an eighth over costing 14, while Allenby clubbed further sixes off bothNeil Dexter and Christian before reaching his hundred - only Glamorgan's secondin Twenty20 - with a lovely extra cover four off Harris from the first ball ofthe 19th over.
By then he had lost Rudolph, caughtreverse-sweeping Dexter, and Mark Wallace, caught in the deep off Podmore afterhitting a few valuable fours off the suffering Harris in a quickfire 18. Glamorgan had needed only 49 from six overs when Rudolph was out, such was the perfect pacing of the chase by the two openers.
Middlesex began slowly, with just 10 runs from the first three overs, in which Joe Denly was quite brilliantly caught on the long-off boundary by a diving Stewart Walters for five, before Morgan ignited the innings.
Morgan pulled Michael Hogan for six in the fifth over, the ball sounding like a rifle crack off his bat, and he also launched Will Owen's fast-medium over long on for another maximum in a ninth over which cost 17 runs.
The scoring rate dipped again when Morgan fell, smartly held low to his left at cover by Hogan off left arm spinner Dean Cosker, but after the 100 arrived in the 14th over the accelerator was pressed by Christian, who drove Cosker for three sixes in a 15th over that brought 22 runs.
Malan, in the same over, was dropped at deep mid wicket by Chris Cooke, when the fielder clearly lost the ball in the low sun setting over Old Deer Park.
After Malan had completed a 38-ball 50,Christian chose the 17th over to plunder two more sixes and a four off Hogan before Cooke atoned for his earlier miss by pulling off a superb low catch as he dived to his left on the cover boundary to end the Australian's brutal innings.
There were two more sixes before Middlesex were finished, one each for Malan and Ryan Higgins hit straight off Owen in a 19th over that went for 17 runs. In the end, though, on a beautiful summer's evening, it proved not to be enough.
