FARID El Alagui bagged a brace as Brentford eased into the second round of the Johnstone's Paint Trophy with victory over neighbours AFC Wimbledon.
The former Falkirk frontman took his tally to five goals in seven games as the Bees won the first-ever competitive meeting between the two clubs.
Debutant Luke Norris, Ben Nugent and Javi Venta were also on target for the hosts, while Jim Fenlon, George Francomb and Peter Sweeney managed consolations for Neal Ardley's side.
Brentford dominated possession in the first 45 minutes, but it was the Dons who had the better chances.
Jack Midson steered the ball wide after he found himself all alone in the Bees box, while Michael Smith skewed an effort wide when he was picked out by George Porter.
At the other end, Ross Worner saved comfortably from El Alagui's weak header.
However, it was the hosts who eventually broke the deadlock five minutes before half-time.
Norris – making his first start – crossed for El Alagui to slot home from inside the six-yard box to give the Bees the edge.
The Moroccan almost made it 2-0 moments later when he skinned two Dons players, only to be denied by the feet of Worner.
Wimbledon started the second period on the front foot, with Porter thwarted by David Button.
And the visitors were made to pay for that miss shortly after when Jake Reeves played in Norris to fire across Worner into the net.
Brentford were out of sight minutes later, with El Alagui rounding Worner to fire into the net for his second and the home side's third.
However, Dons defender Fenlon earned the Wombles a lifeline when he beat Button from long-range.
But Nugent extinguished any hope of a Wimbledon fightback when he restored Brentford's three-goal cushion just after the hour mark.
Sam Saunders sent in a teasing cross to the back stick and the on-loan Cardiff City defender leapt highest to head home.
Sub Venta was next to get in on the act on 69 minutes, firing into the corner after Worner spilled Norris' stinging shot.
The Dons pulled one back through Francomb's superb individual effort, when he exchanged passes with Smith before slotting past Button.
Sweeney's sweet strike in the 90 th minute restored some more pride for the visitors.
