The 22-year-old wing wonder added another before his second half try - after good work from Graham Kitchener - nudged Worcester into a lead they would not let go.
He said: "I'm really happy. It's my first hat-trick for the club and it's always great to get over the line.
"We found it tough, it was a bit of a reality check after last week and that is what we needed. You are going to get tough days like this when you travel a long way.
"It is job done but we are still disappointed with our performance and I know Richard Hill will want more from us.
"We didn't underestimate them. They are a good side, a professional outfit who wanted to prove a point. It was a battle and something we can learn from."
Richard Hill was also pleased to see his young wing get off the mark for the league season and added: "I was pleased with Miles. We need one of the three in Tom Arscott, Miles Benjamin or Marcel Garvey to score tries.
"If one has a good day, like Marcel did last week, then that is great. Miles was disappointed he didn't get over the line last week so I'm delighted for him.
"I really want to generate that competition between them all for tries - that will only make them sharper."
