David Willey struck a century as Northamptonshire thrashed Warwickshire by 125 runs in the YB40 at Edgbaston.
The 23-year-old hit his maiden Twenty20 half-century and took a hat-trick in Northamptonshire's triumph over Surrey nine days ago but was in even better form in carving out 167 from 101 balls.
The visitors won the toss and opted to bat and Willey quickly set about vindicating the decision with some ambitious stroke-play - putting on a first-wicket stand of 69 with veteran David Sales.
Jeetan Patel led the Bears attack and took two 2-32 but failed to slow down Willey, who needed just 22 balls to move from his half-century to his century with Rob Keogh (61) providing valuable support.
Tom Milnes finally sent Willey packing but the damage was done; his 10 sixes helping Northamptonshire post a colossal 324-6 from their 40 overs.
Willey wasn't done there - he claimed the first wicket of the Warwickshire run chase by tempting Varun Chopra into a false shot, and it took some cautious batting from Will Porterfield (44) and Freddie Coleman (34) to steady the ship.
Once Muhammad Azharullah (4-20) got in on the act to skittle out the middle order, the tail quickly followed as Warwickshire fell hopelessly short, losing their last eight wickets for just 82 runs.
