Dublin 2-25 Wexford 1-12
Dublin produced a convincing second-half display to brush Wexford aside as goals from Cormac Costello and Paul Flynn contributed to a 16-point victory for the All Ireland champions.
Wexford managed a goal of their own through midfielder Daithi Waters while Ben Brosnan impressed with six points.
But once Costello goaled shortly after half-time, the result was never really in doubt as Jim Gavin's men coasted home comfortably.
Dublin could have had at least three goals in the first-half but they came up against a determined Shane Roche in the Wexford goal. The goalkeeper denied Paul Mannion twice while half-back Adrian Flynn blocked a goal-bound Mannion shot to frustrate Dublin who were very ordinary in the first half.
Dean Rock bagged four frees while Ben Brosnan scored four great points for Wexford in a half that ended 0-10 to 0-6 in favour of Dublin.
The second-half could have been made a bit difficult for Dublin had Wexford's Conor Carty taken a golden opportunity just a minute after the restart.
The corner-back slalomed through the Dublin defence but his left foot shot was straight at Cluxton who parried before James Holmes pointed the rebound.
This shock semed to wake Dublin and the responded with four unanswered points, with substitute Costello grabbing two of these points before rattling the net in the 46th minute after a clever hand pass by Michael Darragh Macauley sent him through on goal.
Wexford responded with a goal from Waters after 59 minutes to make it a seven point game.
But two points from substitute Tomás Brady steadied Dublin again who turned on the style late on with Diarmuid Connolly, Eoghan O'Gara, Paul Flynn and Costello all registering scores before Flynn blasted home Dublin's second goal to send the Dubs on their way to the Leinster final.
Jim Gavin's men will look for their fourth Leinster crown in a row when they play rivals Meath in the decider.
