Tom Haines has been named as Sussex's one-day captain for 2022.
"I'm really excited," Haines said. "I felt like I got to grips with the role this year and I felt more comfortable the longer I did it. It's great to be backed to do it again next summer.
"Whatever its position in the calendar, we'll be taking the Royal London Cup extremely seriously. The club see it as an important part of its plans, and I want to win it and bring a trophy to Sussex.
"I was encouraged at my ability to do my job with the bat at the same time as leading the team last summer and I'm really looking forward to doing that again. Above all, I'm extremely proud to be a captain at my boyhood club."
Opener batter Haines made his List A debut during the summer, scoring a maiden hundred while averaging 36.00 from seven innings. He was also the leading run-scorer in the County Championship, with 1176 at 47.04, despite Sussex finishing up with the wooden spoon.
Ian Salisbury, Sussex's Championship and one-day head coach, added: "This is the next step for Tom as a cricketer and a person who has already developed hugely over the last 18 months. I was very impressed with Tom's leadership last summer, which itself developed massively during the time he captained Sussex.
"The way he has matured is a great example for our other young players and that makes him the perfect man to lead the Royal London Cup side."
