The youngster, who has been in the club’s academy since the age of 12 having previously been in the youth set-ups at both Liverpool and Everton, got his first taste of involvement with the first team as an unused substitute in the final regular National League fixture of the 2016/17 season away at Maidstone United.
Tranmere manager Micky Mellon said: “The club has a proud history of bringing players through the academy and into the professional ranks and Patrick is the latest in the long line of players to have done so.
“He is a goalkeeper with a lot of potential, has good handling and distribution so we are looking forward to working further with him”.
