FFA Cup pics: Palm Beach Sharks v Central Coast Mariners
The A-League outfit never looked troubled but it was the introduction of Matt Sim in the second-half that proved decisive as he put away four goals in the space of 20 minutes.
The Mariners are the first to book their place in the final four, while the Sharks loss leaves just two Member Federation teams in the tournament - Bentleigh Greens and Adelaide City.
