Harlequins boss Conor O'Shea praised the spirit of his young side after they produced a valiant second-half defensive display to keep out Bath and secure a 21-12 LV= Cup win over Bath at The Stoop.
Fly-half Ben Botica only played the first half but his 15 points set the Aviva Premiership leaders on the way to their second victory in the cup competition.
"You can't coach bottle," Quins director of rugby O'Shea said after his side dominated the first half and survived the second to make it two wins from two cup matches. "I couldn't be prouder of that performance."
He went on: "We started really well and had great tempo but didn't get the try that maybe some of the play warranted.
"But Bath are a strong side and they were always going to come. We started to lose a number of players with knocks and bruises."
Bath paid the price for giving away 21 penalties during the match and defence coach Mike Ford said: "We are going to have to look at the penalties we conceded.
"They had a great start. The last 50 minutes we were in control of the game but we struggled to get over the line."
Forwards coach Neal Hatley agreed: "We weren't great first half and gave away an unacceptable number of penalties.
"We had the majority of possession and territory in the second half but we lacked that last cutting edge. We got a bit inaccurate against a good defensive side."
