Tipperary 2-18 Dublin 1-11
John McGrath's 10-point haul proved to be the difference as Tipperary claimed their first Electric Ireland All-Ireland Minor Hurling title since 2007 at Croke Park this afternoon.
William Maher's charges were in superb form throughout and laid the foundations for this replay victory thanks to a clinical first-half display.
The Premier County failed to register one wide in the opening 30 minutes, with goals from Man of the Match Tadhg Gallagher and Mark McCarthy helping them to a 2-10 to 0-5 interval lead.
Both sides settled quickly early on and were level on two occasions inside the opening six minutes, with Paul Winters and Eoghan O'Donnell taking Dublin's points, while McGrath was on target for both of Tipperary's scores.
However, once McGrath snatched his third point in the eighth minute and McCarthy registered a ninth minute goal, there was no looking back for Tipperary.
McCarthy leaving both Robert Murphy and Shane Barrett in his wake, before smashing the ball past Dublin goalkeeper Cian Mac Gabhann, as the Toomevara clubman claimed his sixth goal of the Summer.
James Roche helped cut the deficit to a goal with a brace of points for Dublin inside 45 seconds, but again Tipperary upped their game.
Gallagher snatched his side's second goal in the space of five minutes, with Barrett caught for the second time as the Kildangan clubman outpaced the Na Fianna defender, before placing Tipperary into a 2-4 to 0-4 lead.
McGrath continued to slot over points from all angles, as Tipperary held three quarters of the possession.
Two goals were the difference with 12 and a half minutes remaining, after Winters slotted over his second point.
Amazingly Dublin weren't to score again in the second quarter, as Tipperary took full control on the score-board.
However, the Metropolitans weren't without their scoring chances with Winters and Conor McHugh registering wides in quick succession.
Tipperary continued to impress, closing out the half with five unanswered points, including three from the stick of McGrath, with Stephen Cahill and Mark McCarthy also on target to ensure a 2-10 to 0-5 half-time lead.
Dublin introduced Kevin O'Flynn in place of Robert Murphy at the interval, while Costello was moved to full-forward for the second half.
McGrath and Tipperary failed to ease up on the restart, with the half-forward registering his eighth point 67 seconds into the second half.
The Metropolitans' scoring deadlock was eventually broken in the 33rd minute when Costello claimed an excellent score from play.
Dublin continued to pressurise the Tipperary defence, but with little reward.
Winters blasting a close-range free straight at the Tipperary defence in the 34th minute, before sending another effort wide of the target 90 seconds later.
Scores were hard to come-by with a scoreless six minute spelling coming after Costello's point, broken with a first of the half from Winters.
Tipperary scored five of the next six points, with Gallagher and Sean Maher impressive to take a 2-16 to 0-8 lead with 10 minutes left on the clock.
Dublin weren't finished by any means with Winters continuing to plug away from placed balls.
Shay Boland's charges hit their best spell in this game registering 1-3 without reply with full-forward Oisin O'Rorke netting a 52nd minute goal after getting onto a breaking ball.
Winters and O'Rorke added points to cut the gap to eight points, but this was as good as it got for Dublin as a brace of McGrath scores sent Tipperary on the way to their 19th title.
After the game Tipperary captain Bill Maher received the Irish Press Cup, while for Dublin their wait for a first All-Ireland MHC title since 1965 continues.
