Owen Williams scored twice and Lloyd Williams, Tom Williams and Dafydd Hewitt once as they came from 17-9 down at half-time to win - Gareth Davies with all their points in the first half.
However Patchell dismissed his huge drop goal as 'hit and hope' and gave the sense that he wasn't going to get caught up in his contribution against English outfit Sale.
"They rarely come off and it is one of those things you practise in the schoolyard or down the club when you are a kid," Patchell told WalesOnline.
"Fortunately it went over and everyone was saying it was a great kick. But if it had missed everyone would have been saying what is he doing?"
"Some weeks the kicks come off and others they don't. Against Sale they came off and we scored a couple of nice tries from it.
"We spoke at half-time about needing to get some territory and hold onto the ball in crucial areas. The forwards worked really hard and they were outstanding.
"As a No.10 you just have to reward your forwards for their hard work and need to point them in the right direction."
