While the Ayrshire side were losing 7-1 at Yoker, Frew were up against stuffy Cumbernauld United at home.
Chris Zok got the home side off to a dream start when he scored after two minutes, but the visitors equalised four minutes later courtesy of a Dominic O'Halloran penalty.
Hot-shot Zok fired home his 22nd goal of the campaign to restore Frew's lead, but after having both Craig Hill and Paul Hanlon sent off, nine-man United grabbed a last-gasp equaliser through Nico Petrucci.
Frew joint boss Martin Ferry was at a loss to explain why his side didn't make more of their obvious numerical advantage.
He said: "It was definitely two points dropped when you consider they were down to nine men and we were leading with just a couple of minutes to go.
"I always thought they might get another chance, though, and when the ball came into the box it took a crazy bounce.
"And, when our keeper clawed the ball out, it fell at the feet of one of their guys a few yards from goal. But, fair play to Cumbernauld for getting a point."
Ferry, who shares managerial duties with Colin Clark, added: "Sometimes when you're up against nine or ten men, tactics go out the window.
"No-one knows who they're supposed to be marking – sometimes I think it would be easier to level it up at nine-a-side!"
Tough-talking Ferry is now desperate for Frew to get back on track this Saturday when they host mid-table Maybole.
Earlier in the season, the Western Parkers won 3-1 at Ladywell Stadium, but Ferry has warned his players that a repeat scoreline is anything but a foregone conclusion.
He said: "Maybole are a big physical team and have good players. They have been on a good run recently and will be hard to beat.
"Everything we do at the moment is geared towards staying in the First Division. We're not safe yet – despite being joint fourth top.
"We have 27 points and I reckon the safety net will be 34, so we have a wee bit to go yet. Then, and only then, will I agree that we're safe."
Ferry is hoping that form man Zok can help fire Frew to their safety target, but knows that with every goal comes a potentially heavier price to pay.
He explained: "Chris is already attracting attention. There have been people hanging around our games, but he's a Renfrew player at the moment.
"He scored two again last Saturday and is in the form of his life. He really is a player with a Super League pedigree.
"We lost Willie Sawyers last season to a top-flight club, but hopefully Chris will see that we have aspirations of playing at the highest possible level."
One player who has headed out the exit door is former Clyde player Drew Ramsay – and he goes with the best wishes of Ferry ringing in his ears.
The talented defender, who is 20-years-old, has just touched down in Oz, where he hopes to carve out a new career with Melbourne Victory or Melbourne Heart.
Ferry said: "Drew was reluctant to tell us he wanted to leave, but he is an honest big lad and I wish him all the very best in Australia.
"I hope he makes it, but if there are any issues and he finds himself back on Scottish soil, he's welcome back at Western Park. He is a big lad with a superb left foot and I reckon he has every chance of making the grade."
There has been plenty of player movement in the West Region, with East Fife midfielder Jamie Pollock having signed for Kirkintilloch Rob Roy.
Two experienced strikers are also on the move. Paddy Flannery has left Rutherglen Glencairn, while Keigan Parker has been released by Irvine Meadow.
Kilbirnie Ladeside have taken talented midfielder Frank Gibson on loan from Medda.
