Barmby cancelled out Darius Henderson's opener as Watford briefly threatened a stirring comeback in the semi-final second leg at a packed KC Stadium before succumbing to a convincing 4-1 defeat, 6-1 on aggregate.

Substitute Folan climbed off the bench to add his side's second after former England international Barmby had notched his second goal against Adrian Boothroyd's side in the space of four days.

Garcia and Doyle then grabbed a goal apiece late on as Hull romped to victory to spark a pitch invasion at the full-time whistle.

Tigers boss Phil Brown will take the majority of the plaudits after guiding a club seemingly in freefall when he took charge in December 2006 to safety last season and now to within one game of securing promotion to the Barclays Premier League.

Perhaps even more poignant is the fact it was two Hull-born players, Barmby and Dean Windass, who scored the goals over the two legs that in the end sent their hometown club to Wembley.

As for Watford and boss Boothroyd, they are left to reflect on a run of one win from 16 games which scuppered any hopes of an immediate top-flight return.

Despite starting the evening with the comfort of a two-goal cushion following a convincing 2-0 win in the first leg on Sunday, Hull were poor early on.

Boothroyd's boys needed an early goal if they had any hope of turning the tie around and it duly arrived after 12 minutes, with Henderson making a dramatic return to the side from suspension.

Michael Turner's lofted header caused unrest in the Watford defence and Jay DeMerit's weak headed clearance fell to Garcia, who looped a goalward header over the advancing Lee and the outstretched Barmby bundled the ball over the line from right underneath the crossbar to ease the home side's nerves.
