Ross Taylor smashed an unbeaten 80 from just 33 balls as Durham claimed a record-breaking 71-run victory over Leicestershire on Monday.
The New Zealander cleared the boundary nine times and shared an unbroken stand of 117 from a mere 45 balls with Dale Benkenstein in the Friends Provident t20 clash at the Emirates Durham ICG.
The Dynamos surpassed their highest ever total in Twenty20 cricket, blasting 225 for the loss of only two wickets in the allotted overs.
Taylor also bettered Ian Blackwell's Durham record score of 79 by one run as the hosts plundered 81 runs from the last four overs of their innings.
Durham's total was also the highest in the competition so far this year, and although Leicestershire kept up with the required run rate in response, their wickets also fell in rapid succession until they were dismissed for 154.
Naddem Malik (0-29) conceded only two runs in the first over of the Durham innings but the runs were soon to start flowing.
Captain Phil Mustard and Blackwell put on 102 for the first wicket before the former lifted Claude Henderson (1-22) to long-on for a quick-fire 65.
That brought Taylor to the crease, who needed only five overs to blast his half-century from 23 balls.
Blackwell departed for 37 after heaving to Matthew Hoggard but the scoring did not let up as Benkenstein made 35 off 17 balls to compliment Taylor's hitting.
Leicestershire were well aware of the need for quick runs as they began their innings, but Brad Hodge (10) was too eager as his wild swing was caught by Taylor at backward point.
Ben Harmison (2-35) claimed the next two wickets before Blackwell (2-16) struck with his first ball to dismiss James Benning (15).
The visitors' innings was falling apart as Paul Nixon (1) was stumped as he swung wildly at Blackwell.
James Taylor made a rapid 38 but was then bowled by Gareth Breese (1-14) as all hopes of a Leicestershire win slipped away.
England star Paul Collingwood mopped up the tail, taking four of the last five wickets to finish with figures of 4-13.
