Ramnaresh Sarwan has taken over from ex-England bowler Matthew Hoggard as Leicestershire four-day captain.
Batsman Sarwan, 32, impressed during his first season at Grace Road, with a Championship batting average of 40.91 and has a contract until 2014.
Hoggard, who was named captain when he joined ahead of the 2010 season, gave up the one-day skipper duties in July.
"I have enjoyed being captain but feel it is the right time to hand over the reins," Hoggard, 35, said.
Chief executive Mike Siddall added: "The club wishes to acknowledge the contribution Matthew has made as captain of the club over the past three seasons, leading the team to a fantastic third T20 trophy win last year."
Head coach Phil Whitticase said: "I've really enjoyed working with Matthew over the past three years, especially during our successful T20 campaign.
"It is important for everyone to get behind Ronnie (Sarwan) as we look to take the club forward."
