Warwickshire trio Laurie Evans, Oliver Hannon-Dalby and Richard Jones have all signed new contracts with the club.
Batsman Evans, who joined the Bears from Surrey in 2010, has extended his contract until the end of the 2017 season.
Evans, 26, made a major breakthrough in 2013, and although he has had a disappointing season in the Championship, he has been in good form in the NatWest T20 Blast, scoring 221 runs at 31.57 to help his team to Finals Day.
Fast bowlers Hannon-Dalby, 25, and Jones, 27, have been on the fringes of the first team this season.
Jones, who joined from Worcestershire in the winter, had a brief spell on loan at Leicestershire but that was cut short by injury.
He has signed a one-year extension which keeps him at the club next season.
Hannon-Dalby, who arrived from Yorkshire ahead of the 2013 season, has been a regular member of the limited-overs side and he has signed a two-year contract extension.
Director of Cricket Dougie Brown told the club’s website: “We’re at a crucial time in the season where we’re competing for honours in all three competitions, so having Laurie, Oliver and Richard commit their immediate futures to Warwickshire is excellent news.
“All three players have made important, match-winning contributions to the team this season.”
