Adam Lyth's dashing innings of 59 was the springboard for Yorkshire's emphatic 104-run victory over hapless Worcestershire at Headingley.
Lyth smashed his 59 from just 24 balls in the Friends Provident t20 clash to enable Yorkshire to reach a Twenty20 best score for them of 213-7.
That score was always likely to be more than enough to defeat a Worcestershire side that had lost five on the bounce in the competition - and so it proved as they struggled to 109 all out in reply with three overs still left.
Lyth, who only made it into the side because of a shoulder injury to Jacques Rudolph, opened with Andrew Gale and watched on as his captain began by hammering Jack Shantry's second and third deliveries for four and six.
With two more blistering boundaries off Richard Jones, Gale had raced to 19 off six balls but in the same over he skied a shot to former Yorkshire batsman Phil Jaques at mid-wicket.
Gale's departure was the signal for Lyth to go on the rampage with an 18-ball half-century, the joint third fastest in domestic Twenty20.
So ferocious was his hitting that his first 48 runs off 16 balls were made up of nine fours and two sixes before he scampered a single and then ran a two to complete his half-century.
And when Sanath Jayasuriya was driven for six over long on and cut for four by Lyth the home side had brought up their 50 in just 3.5 overs.
The second wicket stand reached 108 in seven overs when Herschelle Gibbs fell for 40 from 25 balls, and Lyth followed as his knock was ended by Jayasuriya, who pinned him lbw after he had struck 10 fours and two sixes.
An upset never looked likely because Worcestershire then lost early wickets in a futile attempt to get on terms.
Jaques was caught behind off Steve Patterson's first ball and Ali fell to a well-judged catch by Anthony McGrath.
Lyth continued to enjoy himself with a stunning boundary catch to bring Tino Best the wicket of Jayasuriya and Richard Pyrah dismissed Jack Manuel in his first over.
Off-spinner Azeem Rafiq destroyed the middle order with three for 23 off his four overs while Pyrah snuffed out the tail to give him figures of 3-12.
