Field says he knows exactly what to expect from the Championship.
Leigh have confirmed the signing of Callum Field for the 2020 season.
A second rower, prop or centre, Field was born in Pontefract and is a product of the Wigan academy set-up.
Field said: "Leigh are a top end Betfred Championship club and I am excited to be joining them ahead of what is going to be a big season.
"I have played against Leigh before and know they are always a tough team to beat and I'm looking forward to being part of the squad coach John Duffy is assembling.
"I have played a number of games in the Championship so know exactly what to expect. John is a straightforward coach who demands his teams work hard."
Field made his Wigan debut against Swinton in May 2017, going on to pull on a Warriors jersey four more times that season. He also played three times for Swinton while on dual registration.
The following year he played five times for Wigan, once for Swinton Lions on dual registration and twice at London Skolars. This year, he featured 13 times for Dewsbury Rams on loan.
Leigh head coach John Duffy said: "I coached Callum over at Wigan when he was about 16. He's one of the best forwards I've seen come through in recent years but he didn't get the opportunities at Wigan.
"He played at Dewsbury for a s spell last season so he knows what the Championship is about. It's going to be a big learning curve for him and hopefully he can get plenty of game time.
"Callum is an aggressive player, someone I like watching and someone who fits in with how we want to play."
