The Cricketer runs down all you need to know ahead of the 21st edition of English cricket's premier 20-over competition, with Hampshire Hawks bidding to defend their title...
The 21st edition of English cricket's premier 20-over competition the Vitality Blast.
The competition begins on Saturday, May 20 with the first-ever Blast Off launch event at Edgbaston. Derbyshire Falcons and Lancashire Lightning, last season's runners-up, kick off the new campaign followed by Birmingham Bears against Yorkshire Vikings. The group phase then runs until the final round on July 2. The knockout phase is scheduled as follows:
Thursday, July 6: Quarterfinal 1 (TBC), Quarterfinal 2 (TBC)
Friday, July 7: Quarterfinal 3 (TBC), Quarterfinal 4 (TBC)
Saturday, July 15: Finals Day (Edgbaston)
The 18 first-class counties are split into two regional groups, North and South, based on their location in England and Wales.
Every county plays 14 group matches, seven at home and seven away. The exception this year are Derbyshire, whose opening 'home' game is being held at a neutral venue.
The top four sides from each section play the quarterfinals in the week immediately following the end of the group stage. There is a single reserve day for each knockout match. The winners of those four ties qualify for Finals Day at Edgbaston, when two semi-finals and a final are played to determine the eventual winner.

The top four sides from each regional group are kept apart in the last eight. The path to the semifinals are also set as follows:
North 1st vs South 4th/South 2nd vs North 3rd
South 1st vs North 4th/North 2nd vs South 3rd
North Group: Birmingham Bears, Derbyshire Falcons, Durham, Lancashire Lightning, Leicestershire Foxes, Northamptonshire Steelbacks, Notts Outlaws, Worcestershire Rapids, Yorkshire Vikings
South Group: Essex Eagles, Glamorgan, Gloucestershire, Hampshire Hawks, Kent Spitfires, Middlesex, Somerset, Surrey, Sussex Sharks
Every county, bar Derbyshire, will play seven home and away fixtures during the group stage. The quarterfinal hosts are determined by whichever team finishes higher in the group. Edgbaston, which has hosted 14 of the previous 20 Finals Days, will again be the stage for the blue riband day on the English men's domestic calendar.

Three-time winners and reigning champions Hampshire Hawks are the team to beat in the eyes of the bookies this year at 8/1 followed closely by Surrey, who were stunned in the last eight by Yorkshire. Last year's runners-up Lancashire Lightning are available at 9/1 after narrowly missing out on the title.
Other teams to keep a close eye on this year are Somerset (9/1), who were last victorious in 2005, Birmingham Bears and Notts Outlaws (both 10/1).
Last year saw one of the most dramatic finales in Blast history.
Lancashire and Hampshire contested the final after beating Yorkshire Vikings and Somerset respectively during the afternoon semifinals.
In the final, Hampshire batted first and were reduced to 111 for 7 in the 15th over before Ross Whiteley and Chris Wood rallied to help them to set 153 to win.
Lancashire started the reply strongly, easing to 72 for 1 in the eighth over and looked in prime position to secure a second title, following on from their success in 2015.
But Hants put the squeeze on their opponents, to leave Lightning needing 11 off the last for victory. Luke Wood was run out to leave six required off two, an equation which was cut to four from the last delivery.
Nathan Ellis appeared to have secured victory for Hampshire, bowling Richard Gleeson, but celebrations were cut short when the delivery was adjudged to be a no-ball.
The Australian went again and despite Lancashire's best efforts, Hampshire claimed victory by a single run.
Tickets can be found for all counties via the ECB website.
