31 points in the first half were matched with 31 points in the second half as tries from Jack Clifford, Luke Wallace, Sam Smith, Ollie Lindsay-Hague and a brace of tries from both Peter Browne and Darryl Marfo contributed to the victory.

Ben Botica was again on form with the boot converting five tries and kicking one penalty. In the second half Rory Clegg took over the kicking duties and converted two tries.

It was an impressive display from a strong Harlequins side who were not afraid to throw the ball around in the slippery and wet conditions. The forward pack dominated in the set piece and were equally effective in open play, scoring six of the nine tries.

The blistering pace of Jordan Burns, Charlie Walker and Lindsay-Hague posed a constant threat to the Exiles' defence and regularly set up scoring platforms.

In comparison, the London Irish side, who fielded eight trialists, struggled to get into the game and any possession gained was regularly lost through ill-discipline and handling errors, preventing the team to gain real momentum.

Clifford opened the scoring after just seven minutes, capitalising from a neat grubber kick by Clegg through the defence.

Botica added a penalty before Marfo scored before the 20 minute mark. Clean lineout ball from Charlie Matthews provided the forwards a good driving platform. The forwards drove over the line from five metres and Marfo popped up from the pile in possession.

When the Exiles' James Sandford was sent to the sin-bin, it didn't take long for Harlequins' numerical advantage to count. Close to the Irish line, the forwards worked the phases and despite an overlap out field, captain Wallace powered his way over the line.

London Irish launched their biggest threat of the half but when the score seemed imminent, Brian Blaney knocked on. Blaney and Irish were dealt another blow when the hooker was stretchered off on the half hour mark. Thankfully, the hooker was ok and the precautionary measures were just that.

Marfo, who had a very strong all round game, scored his second before half time following great offloading and interplay from the visitors. Botica kept his 100% record and at half time, Quins lead 0-31.

In the second half, Louis Grimoldby made his first appearance as a full-time academy member at fly-half and controlled the game well, this change pushed Rory Clegg into the centres.

On 37 minutes, Browne scored the first of his two tries thanks to an electric burst of pace from Burns. The scrum-half broke into the 22 and when the ball was stretched wide, the second-row scored. Botica converted for the final time as the duties fell to Clegg.

London Irish began to gain momentum as the hour mark approached and again when a score looked imminent, they knocked-on. From the resulting scrum, Harlequins' dominant pack won a penalty and the visitors cleared.

Harlequins scored two tries in quick succession and Marfo was key in both the scores. A surging run from the front row forward set up a try for Smith, before his offload set up a surging run for replacement, Kyle Sinckler which would eventually lead to Browne's second.

Dave Ward, who was making his first appearance in a Quins jersey made a great impact 10 minutes after he came on. The hooker stole a lineout on half way, dodged two tackles in the process of making 30 yards and set up Lindsay-Hague with the simplest of touchdowns on 70 minutes.

Mantella completed the evening's scoring on 80 minutes following a break from Walker inside his own 22. The England U20 showed great skill to avoid two defenders before setting up the winger to score from 50 metres out. Clegg's touchline conversion was the last act of the game, but unfortunately hit the post.
