Glamorgan will be led by Chris Cooke and David Lloyd next season after a captaincy reshuffles. Cooke continues as Championship captain while also taking charge of the T20 side, while Lloyd will step up for the Royal London Cup, when Cooke will be absent at the Hundred.
Cooke, 33, oversaw Glamorgan's best Championship campaign since 2015, as the club kept alive promotion hopes until the final weeks before finishing fourth. He adds the Blast captaincy for 2020, with Colin Ingram relinquishing the position.
"It was an honour to lead the club last year and I'm delighted to continue in the role," Cooke said. "We saw a lot of improvement in our County Championship performances last season and it's something we want to take into the Vitality Blast.
"It's going to be an exciting season and we can't wait to get started and hit the ground running in April."
Allrounder Lloyd, 27, has been a regular member of the List A side since 2014 and took charge in one Royal London Cup game last season when Cooke was injured.
"I thoroughly enjoyed stepping in as captain and it's a really proud moment to be asked to lead the side in the Royal London Cup," Lloyd said. "We have a great bunch of lads at the club and a lot of talent in the squad, so there is no reason why we can't build on last season's improvement and reach the knockout stages of the competition."
Cooke will be absent with Birmingham Phoenix during the Hundred, which will also feature Ingram, who was signed as a 'local icon' by Welsh Fire.
Glamorgan's director of cricket, Mark Wallace, said: "Chris did a fantastic job in his first season in charge and led the side with a great deal of enthusiasm and skill. He commands a lot of respect in the dressing room and deserves the opportunity to carry on his good work from last year and take the club forward.
"It's also great news for Glamorgan that David is taking over the 50-over captaincy. He showed many leadership qualities last year and did a good job under tough circumstances when he deputised for Chris."
