It was a dream start for Harlequins with Jack Clifford, who has recently been recalled into England’s Six Nations squad, scoring the games’ first try. Marcus Smith made the conversion.
Agen wing Valentin Saurs did respond soon after with a try of his own – which was converted by Jake McIntyre – but it was not long until Harlequins regained the lead.
In-form back-rower Alex Dombrandt found Max Crumpton on his inside shoulder to cross over the try line. Smith was unable to find the conversion.
The visitors finished the first half in excellent fashion after Gabriel Ibitoye found a hole in Agen’s defence to dot down for their third try. Smith’s successful conversion gave Harlequins a 12-point lead at the break.
The try-scoring bonus point was claimed shortly after the interval when Danny Care’s beautifully-timed chip was collected by Nathan Earlie who powered over the whitewash. Young fly-half Smith added the extra points from the tee.
Care was again at the heart of Quins’ next try, putting his boot to good use with a chip in behind, which was gathered by Joe Marchant who piled over. Smith ensured the maximum points were taken with his successful conversion.
Jordan Peyri and Fouad Yaha went over for Agen late on but Harlequins weathered the storm to secure victory and top the group with 21 points, edging out Benetton.
