In the first ever professional snooker tournament staged in South America, Murphy took just 64 minutes to win a battle of two former world champions.
Sale-based Murphy picked up the trophy and a cheque for $40,000 at the Costão do Santinho Resort, to conclude the 16-man invitation event.
A break of 81 gave him the first frame and he took a scrappy second for 2-0. Runs of 54 and 70 saw Murphy make it 4-0 at the interval, and he delivered the coup de grâce in the next with a 139 total clearance.

"I got better with each match through the tournament, and played my best in the final," Murphy said.
"It's a great opportunity we've been given, to go around the world playing the game we love. I'll have very fond memories of Brazil and I would love to see this become a regular event. The people here are very enthusiastic, they have enjoyed it and I think this is a market that can be expanded.
"This is a great time for snooker and it's very exciting to be part of it, with so many new formats and new locations."
Murphy was dominant throughout the tournament and conceded just two frames in his four matches.
