Director of Rugby Ruddock praised his side for their effort and hoped that home advantage in the coming weeks would prove vital.
"We're missing that bit of luck, margins are tight and they went against us, that was heartbreaking," he said.
"We charged down two kicks and they could have run better for us. The effort was fantastic and I feel for the boys. It would have been good for them to see a result.
"But we have more home games left than away, that can be a crucial factor."
Ruddock was pleased with his sides display after recent defeats to Saracens and Harlequins.
But he admitted chances had gone begging on the day and the players were hurting after the game.
"We had four or five good chances but it was a big improvement in performance," he said.
"Our defence was better and we weren't so ill disciplined. The margins are just so tight.
"We had a couple of chances towards the end of the game in the tackle area but things did not go for us.
"I am proud of the players. We didn't concede on the day, we're desperately disappointed not to have won that game.
"I thought we had more territory and possession, we had chances but couldn't convert them."
