After bringing their eight-match losing streak to a halt against France, Rob Howley’s men edged to another victory to keep their Championship hopes alive.
The triumph in Rome was not the prettiest, as the difficult conditions dictated, but Biggar was delighted with the result.
“The conditions were difficult, but we stuck to what we wanted to do and it was a pretty good – 7/10,” said Biggar.
“At the end of the day it’s a win and good sides do that. You look at Man United, year after year, not playing well week in week out but they get three points.
“It’s important that we can win when we’re not playing 100 per cent and that’s what we’ve done the last three weeks. It’s no good playing well and losing, you don’t get anything from that.
“Obviously you’re entertaining people, but internally you get very little from it.
“Once you’ve got that solid base with a couple of wins, it’s important to push on and get a couple more.
“It’s difficult enough coming to Italy anyway, but the wind and the rain in the first half was absolutely torrential.
“It was always going to be about sticking to the game-plan rather than giving a 10/10 performance. We didn’t want to play a lot in our half and the coaches are very pleased with the way we operated it.”
Wales face Scotland next and can set up a Championship decider with England on the final weekend.
And Biggar is relishing the trip to Murrayfield and is desperate to hang onto the famous number 10 jersey.
“We’d have liked to play straight after Paris and straightaway again now, but we’re looking forward to the Scotland test,” added Biggar.
“We’re on a little bit of a roll now. The bottom line is that we deeply want to win and that shone through on the weekend.
“Personally it’s gone solidly, I haven’t set the world alight by any means, but what’s been needed is a bit of control. I’m enjoying the role.”
