In a very expansive game, dictated by the sevens conditions, Harlequins showed promising signs and were rewarded for their earlier efforts with a try from Stegmann on three minutes.
With an attacking scrum five metres from Scottish's line the ball fired out to Clegg. The fly-half shipped the ball to the right and Stegmann darted in to score. Clegg converted, giving Quins a 7-0.
Moments later, Clegg slotted his second conversion, following a try for Marfo. From the earlier restart, Harlequins won a penalty and Clegg kicked to touch. A surging driving maul from the lineout was too powerful for the visitors and Harlequins bundled over. With nine minutes played, Quins lead 14-0.
On 13 minutes, Willie Lipp put the visitors on the scoreboard. From a Scottish lineout five metres out they worked the phases close to the line. Lipp took an inside pass from Ross Samson to score. With Phil Godman's conversion the deficit was reduced to 14-7.
New academy scrum-half Henry Taylor showed Harlequins fans a taste of things to come with two storming runs in the Scottish half. Although the first one resulted in a Quins knock on, his second gave Quins their third try.
A great turnover from Joe Trayfoot in midfield allowed Ollie Lindsay-Hague and Seb Stegmann to charge down the line. Taylor picked from the back of the ruck, just outside the 22 and pranced around the defence to score. Clegg whose kicking had been on form slotted his third of the afternoon.
A third run from Taylor set up Marfo's second. The powerful prop surged over after a number of phases close to the Scottish line. Clegg's conversion eased over the posts for a 28-7 lead.
Scottish gained some momentum towards the end of the half, but failed to cross over and Quins took a 28-7 lead.
The second half began slowly with neither side settling with possession. When Harlequins won a penalty in their own half, replacement scrum-half Jordan Burns lit up the Stoop with a storming run into the Scottish half. Despite two great offloads Stegmann fumbled the ball to break the attack down.
57 minutes and London Scottish got their second try on the board thanks to replacement Chevvy Pennycook. With Quins down to 14 due to an injury to Clegg, it took the visitors a number of phases to break the line. As they built pressure, the numerical advantage told and the visitors scored. With the conversion from Godman Quins lead 28-14.
Scottish continued to pressurise following their score. Good defensive work from Trayfoot and Skinner forced errors in attack.
Scottish put their third try on the board from scrum half Jamie Stephenson. With an attacking scrum five metres from the Quins line, the visitors won a penalty and from the short distance, the scrum-half scored. With the conversion before the water break, Scottish reduced the deficit to 28-21.
Harlequins responded immediately with a two tries in quick succession try from Acadmy new boy, Jordan Burns and Charlie Matthews.
The first came as a result of a break in the midfield from Botica. The Kiwi, who moved to fly-half, offloaded to the young scrum-half to score in the far corner.
Quins received the restart and charged up field to score a stunning try. The early break from Matthews brought play right into the Scottish half. The ball passed through numerous hands and Matthews completed the move he began by scoring. Botica converted twice and Quins lead 42-21.
With less than five minutes left to play Harlequins held on for the win.
