The 19-year-old central midfielder, who turned professional in September 2004, spent the second half of last season on loan at League One side Chesterfield where he made 19 appearances, scoring five goals in what was an impressive introduction to League football.
Ã¢â‚¬Å“I think Jamie was one of the player who progressed unbelievably last season," said Martin. "He played well for the reserves and when we put him out on loan they were very happy with him.
"He came back and I told him if heÃ¢â‚¬â„¢s fit, he could be in the squad. IÃ¢â‚¬â„¢m taking him in the first team squad for the first couple of weeks and if he makes a good impression he has a chance of being in the first 26."
Other Reserve/Academy contract extensions completed over the close season so far have been versatile left-sided player Charlie Daniels, goalkeeper Robert Burch, striker Simon Dawkins and full-back Chris Riley, while summer signing Dorian Dervite Ã¢â‚¬â€œ the French Under-20 captain Ã¢â‚¬â€œ trained with the first and development squads on Thursday.
Ã¢â‚¬Å“Dorian is an international, a big lad, a central defender. We spotted him in France, looked at him and made the decision to take him on a contract,Ã¢â‚¬Â added Martin.
Ã¢â‚¬Å“Everyone at the club knows about Charlie Daniels. In the Academy he was a left-sided player and I feel he can make a career as a full-back.
Ã¢â‚¬Å“Last season he progressed so he deserved it because heÃ¢â‚¬â„¢s a talent.
Ã¢â‚¬Å“Burchy is a young goalkeeper and donÃ¢â‚¬â„¢t forget we also have the likes of Paul Robinson, Radek Cerny and Marton Fulop here. He went on loan to other clubs to improve himself and did that but unfortunately he picked up a nasty injury in the last game of the season. IÃ¢â‚¬â„¢m sure he will be back soon.
Ã¢â‚¬Å“Simon Dawkins looks lively, heÃ¢â‚¬â„¢s fit and confident. He can play as a second striker or on the wing so there is promise there.
Ã¢â‚¬Å“Chris Riley is an attacking full-back and hopefully heÃ¢â‚¬â„¢ll make a career as a Spurs player. There are certain things he has to improve on and weÃ¢â‚¬â„¢ll work on that and heÃ¢â‚¬â„¢s a good lad, one for the future.Ã¢â‚¬Â
