First hour not good enough - O'Shea
Harlequins director of rugby Conor O'Shea admitted his side had been fortunate to maintain their unbeaten Aviva Premiership record with a 17-15 victory over Worcester at Sixways.
An out-of-sorts Quins team trailed 15-3 after an hour and looked certain to suffer their first defeat of the season, but two converted tries - the first from Sam Smith, and the second a penalty try - turned things in the visitors' favour.
"Worcester must be gutted to lose," O'Shea said. "We were very unhappy with our performance today."
He added: "The game was a very start-stop affair it was free-kick after free-kick and penalty after penalty and for 60 minutes we were awful.
"The guys let themselves down but at 15-3 down we could have waved the white flag. It is very satisfying that the boys dug in and secured the win."
It was a disappointing match with neither side playing remotely near their best and, like O'Shea, Worcester head coach Richard Hill was also critical of his team.
He said: "At 15-3 up at home you have got to win these games we were in control but we gave away a soft try from a first phase and credit to them for coming back to win.
"It was a poor game. In the first half we made eight errors in the first 17 minutes and our lineout was a huge concern.
"We couldn't keep the ball for sufficient phases once we had five phases then four and we got two penalties so it is not rocket science."
Worcester suffered a blow when influential captain Kai Horstmann left the field with his side 15-3 up, and Hill reported afterwards: "Kai has pulled a hamstring. It doesn't look good and he will be out for four to six weeks."
