Lancashire have tied three of their seam bowlers down to new contracts.
Kyle Jarvis, who took 62 County Championship wickets last season, as well as Tom Bailey and Gavin Griffiths have all signed extensions at Old Trafford.
"It is imperative that we have a group of strong and talented seam bowlers and all three have had an impressive season," director of cricket Ashley Giles told the club's official website.
"Kyle was the pick of our bowlers in red ball cricket and it was a real shame that his injury stopped him from playing in the final games, while Tom made some excellent contributions in all forms of the game.
"Gav had a T20 debut to remember at Finals Day and to bowl a maiden in his first over was quite remarkable. All three are important to the future of Lancashire."
Lancs also confirmed that academy players Rob Jones and Danny Lamb have signed scholarships with the club.
