The 16-year-old has impressed for the county's second XI this season, scoring a century and fifty in just four matches, which has earned him his first professional contract.
Lancashire Cricket have announced that Rocky Flintoff has signed his first professional contract with the Club.
Flintoff, 16, is the son of former England allrounder Andrew and has impressed for the second XI this season.
He has played for them four times this season, hitting a century against Warwickshire, a week after scoring fifty against Durham at Old Trafford.
This week also saw Flintoff earn his first call-up to the England U19 squad as they take on Sri Lanka in a Youth ODI series later this month.

Flintoff said: "I'm very happy and excited to have signed my first professional contract with Lancashire. It's something that I've been working towards since I started playing cricket, so to sign for my home county is a dream come true.
"I've been with the club since I was eight years old, so to have the opportunity to keep representing the Red Rose is a big honour. I have loved playing for the Second XI so far this season and I'm looking forward to continuing to work hard on all aspects of my game."

"Rocky will be away with the England U19s for the next couple of weeks, and we look forward to welcoming him into the professional squad after that."
