“I've had a great time with the Ospreys and what a fantastic way to hang my boots up”
Williams added: "We'd been showing glimpses that we can play some rugby in that game, but a little bit frustrated by some decisions, some mistakes, letting a few sloppy tries in and uncharacteristic really.
"And we had to play better in the second-half and it's as simple as that.
"The effort has certainly been there all season and it was from the first-half and fair play to the guys, they just gave it their all right to the end again.
"It was commendable from the guys."
Williams' two touchdowns played a significant part in that effort, but he was determined to make a mark.
"That's what I'm here to do and even though it was my last game I knew that I wanted to get involved in that game," said Williams.
"Again, I found it very frustrating, but I'll keep playing right to the end and if there's an opportunity I can sniff it - that's what I'm there to do.
"We seemed to be giving it away most of the time as well with some sloppy tries…a couple of bad decisions, discipline at the start of the second-half.
"We got a great try by Becky [centre Ashley Beck], but then we gave away three penalties in a row. It just didn't look to be going our way.
"But the guys stuck at it right at the end.
"And we've worked hard this year. We've had a lot of ups and downs, a lot of changes in the camp and we've turned it around.
"So fair play to the boys.
"I've had a great time with the Ospreys and what a fantastic way to hang my boots up."
