Kyle Fraser's hat-trick ensured Porthleven capped off a fine week with an excellent 4-2 win at home to Callington Town on Saturday.
The Fishermen fell behind midway through the first half via an own goal but the hosts equalised shortly before half-time when Ross Duncan's fine work on the left teed up Fraser to net his first of the afternoon.
That same link-up provided Port's second goal on the hour when Duncan chested the ball into the path of Fraser, who found the net from the edge of the box.
Charlie Young scored his third goal in four games from the spot to double Port's lead with 15 minutes to go before Fraser wrapped up his hat-trick with another penalty late on.
There was still time for Cally to pull another goal back, but the Fishermen held out to earn their second win in three days, following their first win of the season at home to St Austell on Wednesday night.

A delighted Fishermen boss Graham Blake said: "I'm under no illusions, this a new team again. This is my team now and bar Thommo [player/head coach Jamie Thomson] and Dan Richardson, the average age of the team is 23. It is a young side and they're learning all the time.
"It's off the pitch as well, they're gelling as a team but they're also making friendships for life and that's part of football.
"They are growing as a team and it is a work in progress and we're starting to see the rewards for it."
Fraser stole the show with a superb hat-trick to get off the mark for the season, which was preceded by a chance pre-match chat with his manager.
Blake said: "We had a chat before the game and he said: 'I've had three assists but I haven't scored this season.'
"I said: 'It'll come mate, you're getting your chances, you're creating goals and that's the main thing', and then he goes and bags a hat-trick!"
