Harlequins boss John Kingston was thrilled to see the depth of the club's squad shine through in their shock 17-10 win over Saracens.
The early loss of Joe Marler and prior to that Marland Yarde withdrawing before kick-off meant early introductions for Mark Lambert and Charlie Walker, with Walker going on to score Quins' second try in an impressive first half.
An early Tim Swiel penalty and Tim Visser interception had Harlequins 10-0 to the good and they led 17-0 at half-time following Walker's score, before holding Saracens out in the second half to win 17-10.
"Joe's a massive personality for us. Mark Lambert has been at the club a long time and he took the role seamlessly so early in the game," Kingston said.
"Karl Dickson came on when Danny had to go off after half-time when we were massively under the pump and playing into the wind. He did such a wonderful job.
"Charlie Walker didn't get much notice that he was playing after Marland pulled out before the match. And then James Chisholm stepped in for Jack Clifford, who had that unfortunate injury.
"The way they all played when there was so much disruption was really positive. You expect your big players to play, but those boys stepped in and a wonderful job.
"It must have been a wonderful game to watch, two sides going at it hammer and tongs.
"I'm just so pleased for the players that they got their rewards and an injection in belief and confidence which was very important for the season ahead."
