Conan Canavan scored 1-4 as Tyrone powered past Derry with a 2-16 to 1-12 win in Letterkenny to retain the Ulster Minor title.
After Conor O’Kane’s early goal for Derry, Canavan – nephew of Red Hand legend Peter – raised a green flag as the Oak Leafers led 1-7 to 1-5 at the break.
However, Tyrone pulled clear in the second half before Logan O’Connor’s goal helped seal a seven-point win.
Having produced a stirring comeback to beat Cavan in the semi-finals, Gerard Donnelly’s side now remain on course to defend their All-Ireland Minor title.
“We were very calm at half-time,” Donnelly told Peter Canavan in a post-match interview posted on Tyrone GAA’s social media channels.
“We were two points down but I think we had eight wides at half-time but we knew the chances were there.”
Donnelly’s side will face Galway in next week’s All-Ireland quarter-finals, while Derry also advance to the last eight.
Tyrone will be hoping for more underage success when their Under-20s attempt to win a third successive All-Ireland title in Saturday’s final against Kerry at Croke Park (17:00 BST).
