This is the 11th season of the English domestic Twenty20 competition and it has a new sponsor and a new format.
We are back to two groups of nine teams each - split geographically North and South with the top four teams from each group qualifying for the quarter-finals. Finals Day is at Edgbaston on Saturday 23 August. In all, 70 per cent of all the games will be played on Friday nights, with everything kicking off today!
So let's have a stroll down memory lane and see what the last 10 years of English domestic Twenty20 cricket have brought us...
Ten men have passed 2,000 runs in the competition, headed by Darren Stevens, who has made 2,476 so far. He is closely followed by Darren Maddy (2,379), Murray Goodwin (2,358) and Stephen Moore (2,319) proving that it is pretty tight at the top!
Forty nine centuries have been scored, but only one player has reached three figures on three separate occasions. Ian Harvey scored 100no for Gloucestershire against Warwickshire in 2003, 108no for Yorkshire against Lancashire in 2004 and 109 for Yorkshire against Derbyshire in 2005. Perhaps unsurprisingly, Marcus Trescothick has passed fifty on the most occasions - 17 of them.
No-one has been dismissed for 99 in the competition, but spare a thought for Steven Davies. He was 99 not out for Surrey against Sussex at Whitgift School in 2011 when the Surrey 20 overs ended. He will have taken some solace from the fact that his side ran out winners by 18 runs but Davies is still yet to score a Twenty20 century.
Having a ball
With the ball it has been a two-way race to be the leading wicket-taker. Yasir Arafat currently leads the way with 121 wickets, just two ahead of Azhar Mahmood. They are the only two bowlers with more than 100 wickets, with Andrew Hall (95) and Dimitri Mascarenhas (94) next in line.
There have been 16 hat-tricks in the competition, the most recent being David Willey, who accomplished the feat in last year's final. Jim Allenby made history by taking four wickets in four balls in 2008 playing for Leicestershire against Lancashire.
Two sides have topped 250 in the competition, the highest score being Gloucestershire's 254-3 against Middlesex at Uxbridge in 2011, an innings in which both the openers - Kevin O'Brien and Hamish Marshall - made centuries. At the other end of the spectrum, Northamptonshire were bowled out for just 47 by Durham in 2011 at Chester-le-Street.
Sixteen matches have been tied in the competition, including two memorably on Finals Day in 2011 at Edgbaston, which both went to a Super Over. Astonishingly, both meetings between Nottinghamshire and Northamptonshire ended tied in 2010.
