An average of 109.8 was the mark for the Welshman who wanted to play well after a week where he lost his grandfather.
"I'm over the moon with that performance, I haven't had a great year but I felt that was coming," said Lewis.
"I lost my grandfather last week, it's been a really hard week but I knew I was going to come out here and do well for him tonight.
"In my head I was thinking 'I don't want to let him down' and thankfully I performed well for him tonight, so I'm chuffed with that."
