The 2026 T20 Blast campaign begins on Friday, May 22, with a slimmed-down, restructured format.
Eighteen counties will compete in three regional groups before the tournament concludes in July ahead of The Hundred.
A review by the counties, the England and Wales Cricket Board, and the Professional Cricketers' Association led to a reduction in the group stage to 12 matches per side.
The top two teams from the North, Central, and South sections, along with the two best third-placed finishers, will advance to the quarter-finals on July 15.
Finals Day is set for Edgbaston on July 18.
Defending Champions and Key Contenders
Defending champions Somerset start their campaign in the Central Group with a final rematch against Hampshire Hawks in Taunton.
Somerset coach Jason Kerr noted the difficulty of the competition to BBC Radio Somerset.
"We've seen how consistent we've been in terms of getting to Finals Days and actually only managed to win two in the last five or six," Kerr said.
"It's an incredibly difficult trophy to win but hopefully we can get that monkey off someone's back."
Somerset captain Lewis Gregory emphasized the historic opportunity, as no team has ever secured consecutive titles since the tournament launched in 2003.
"Over 23 years no one's defended it so hopefully we can be the first this year," Gregory said.
Hampshire Hawks enter under new head coach Russell Domingo, who replaced Adi Birrell this summer.
Domingo expressed his anticipation to BBC Radio Solent as skipper James Vince returns to the squad.
"Somerset are defending champions, an established side, a well-balanced side, we have got a few bowling niggles we need to manage," Domingo said.
Lancashire captain Keaton Jennings aims to guide his squad past their previous knockout struggles. The team begins its season playing against Surrey in London on Friday.
"It's not often you start your T20 campaign down in the Big Smoke against Surrey so the boys are excited," Jennings said.
Nottinghamshire Outlaws seek to return to Finals Day for the first time in six years, opening their campaign against Yorkshire.
Outlaws bowler Olly Stone detailed the shifting focus of the squad to BBC East Midlands Today.
"The last couple of years probably haven't gone the way we'd have liked them to but I feel we've made some good steps in the right direction," Stone said.
Women's Tournament and Player Development
In the women's tournament, the focus turns to players missed by national selectors.
Warwickshire batter Davina Perrin is set to compete after being omitted from the England Women T20 World Cup squad by head coach Charlotte Edwards.
"Her time will come," Edwards said.
Sussex head coach Paul Farbrace highlighted the development of all-rounder James Coles, who was the most expensive men's player at the Hundred auction.
"He is one of the best talents in English cricket and has just improved year on year," Farbrace said.
The men's opening round continues on Friday night with Middlesex hosting a match at Lord's, while Essex prepares for its first fixture scheduled for May 29.
