Ayr United suffered a midweek blip, but they can put it right with a win at struggling Queen's Park at 10/11.
Scott Brown enjoyed plenty of wonderful memories at Hampden and he will take his Honest Men just along the road on Saturday.
And Brown's boys can get the job done at Lesser Hampden.
They went down to a 2-1 defeat at in-form Partick Thistle, but prior to that, they were unbeaten in the Championship since the second day of the season.
They had been on an impressive run of four wins and a draw in their last five league games up until their visit to Maryhill.
They face a Spiders side who have a dreadful record at their own home. Not only have they failed to win a home league this season – they actually haven't won a home game since four days into this year.
It's an awful record and Ayr can take advantage with McBookie.com's 10/11.
Arbroath continue to be underestimated despite enjoying a terrific campaign and they look a stand-out price with McBookie.com at 7/4 to win at Airdrie.
The Red Lichties have enjoyed a couple of briliant recent results when they destroyed Queen's Park 4-1 and followed that up by handing leaders St Johnstone their first league defeat of the season by beating them 3-1 last week.
Admittedly, they were both at their Gayfield fortress, but they are a decent side who continue to surprise plenty of folk.
They face the managerless Diamonds who sacked Danny Lennon this week after a turgid period in charge.
They were thumped 4-0 at home by Dunfermline in midweek and they have yet to win a league game all season.
So it's something of a puzzle why they are favourites to an in-form Arbroath side.
St Mirren haven't had the results they deserve and they look overpriced at 19/10 with McBookie.com to win at Dundee United.
Saints lost an injury time goal to Aberdeen last week after they were reduced to ten men and were also defeated in a rare poor display at Kilmarnock.
But they are better than these results show and are due some luck.
United have drawn their last two games at home to Livingston and away at Rangers. Jim Goodwin's side have only actually won once at Tannadice this season and the Paisley side can add to their woes with a win on Tayside.
