Mike Grella scored four as Brentford took another step closer to a Wembley Final in the Johnstone's Paint Trophy by thrashing AFC Bournemouth 6-0.
The game was just about over after the first quarter as Sam Saunders scored his fourth goal of the season and set up Grella's first for The Bees.
Grella added a third moments after half time and Brentford ran riot in the later stages.
Shaleum Logan scored a fourth with 13 minutes remaining before Grella added two more as Bournemouth capitulated and Brentford booked a place in the Southern Section Semi Finals.
Bournemouth may have felt themselves unfortunate to be behind at all after the first 25 minutes, let alone two down, but they will be pointing fingers at goalkeeper Shwan Jalal, who was arguably responsible for both goals.
The first was scored by Saunders when the visitors failed to deal with a corner and Clayton Donaldson laid the ball in to his path.
The wide man fired low and left footed but it was pretty close to Jalal and he should probably have stopped it nestling in the corner.
The second came midway through the first half when the hapless goalkeeper came to meet a Saunders corner but was beaten to the punch by Grella, who nodded home.
The visitors could have been ahead inside three minutes when Scott Malone headed a Marc Pugh cross against the post and then watched as it rolled along the line, hit the other post and bounced in to the arms of Richard Lee.
They had other chances as well, following Saunders' opener, as Pugh beat three men before shooting wide and Michael Symes fizzed an effort narrowly over from 25 yards.
But Brentford were incisive in attack - Jalal saved at the feet of Donaldson as the striker tried to reach a Saunders pass and then clumsily tipped a curling Myles Weston effort over the top.
Saunders was just unable to head in a Weston cross to make it three and Craig Woodman blocked a fierce Pugh shot at the other end but the game petered out a little as half time approached.
The visitors needed to make the running to keep their hopes alive and were unable to create much.
In fact, as half time edged nearer, Brentford looked more likely to add to their lead.
Donaldson had a shot deflected wide and then forced a fine save out of Jalal with a header, although the flag was up for offside so it may not have counted.
Jalal kept out Weston's fierce drive soon after and went full stretch to hold a Diagouraga shot in stoppage time at the end of the first half.
Lee was well positioned to hold on to an acrobatic Steve Cook effort at the end of the first half and the visitors brought on Charlie Sheringham at the break to try and find a way back in to the game.
But within 150 seconds of the re-start, the tie was well and truly over.
Saunders fed the ball inside to Diagouraga and he picked out Grella with a delightful pass, the American striker poked his second of the evening under Jalal to give Brentford a three goal lead.
The Bees continued to pour forward - Grella played in Donaldson but the striker was half stopped and could only get off a weak shot before substitute Niall McGinn had a shot blocked.
Symes came within a whisker of pulling one back for Bournemouth when he met a Sheringham cross at full stretch but his effort clipped the crossbar on its way over.
Lee had to be alert to tip a lofted Pugh effort over the bar and Malone blazed over for the visitors before Jalal held on to a low McGinn shot.
Lee saved an Adam Barrett header but there were still more chances at the other end.
Weston fired a cross along the edge of the six-yard-box with neither Alexander nor Grella able to turn it in before Legge headed another free kick wide.
Brentford's fourth owed much to the persistence of Weston, and goal scorer Logan.
Weston battled with Warren Cummings on Brentford's right and when Malone helped his full back out, Logan was waiting to rob him.
The Bees right back fired in a shot that deflected off Barrett and beat Jalal.
It was five four minutes later when Diagouraga chipped a cross to the far post and Grella rose majestically to head home.
Weston dragged a shot wide as Brentford sought to add salt to Bournemouth's wounds and Grella did so when he headed in a McGinn cross.
Weston curled a shot narrowly wide in the dying seconds and the visitors almost pulled one back when Steve Fletcher's header from a Pugh corner was diverted wide by Sheringham.
But it was Brentford's night, and, in particular, Mike Grella's night.
He almost scored his fifth of the night in stoppage time with a lob that beat Jalal all ends up but cannoned away off the post to safety.
