Harlequins take an impressive 20-3 lead over Wasps into halftime. Quins started the match sensationally, with two tries and a penalty seeing them race out to a 17-0 lead after the opening 15 minutes. Quins kept the scoreboard ticking over with a penalty around the half hour mark to extend their lead. Wasps would slot a penalty to get on the board with the final play of the half.
