Fabio Silva's first involvement sees him shank a cross high over the bar.

The conditions are wild, tbf.

This weather... grim stuff.

Here comes Fabio Silva.

The Wolves loanee replaces Cyriel Dessers.

The boy looks absolutely freezin' as he waits to enter the pitch.

Another Rangers corner, this one from the left, which doesn't beat the first man.

A Rangers corner now and it comes in from James Tavernier.

John Souttar meets it but it's a comfortable enough save in the end.

It's a well-worked set play to the edge of the box and Ryan Blair guides wide via a deflection.

The resulting corner is flicked over.

Better from the fourth-tier hosts, who win a corner...

Stevie Farrell must have a wry smile when he sees the quality coming off the Rangers bench.

The gulf is there for everyone to see.

Triple Rangers change as Todd Cantwell, Ridvan Yilmaz and Nico Raskin make way for Ryan Jack, Tom Lawrence and Borna Barisic.

A John Lundstram shot is blocked and Dumbarton look to play out, but they're being suffocated by Rangers.

A rare Dumbarton shot as James Hilton drags one wide from range.

Another pitch comment, but this is old school.

The corner comes to nothing.

Rabbi Matondo bursts through a challenge and makes it into the box, but his finish rolls just wide.

It must have taken a nick or been saved as a corner has been awarded.

We're back under way.

They're turning the screw, as you'd expect. The conditions are difficult but the second goal should put it to bed.

It's another assist from Tavernier. A 10th goal of the season for Dessers - a man we've spoken an awful lot about. Ten isn't bad, and it's decent for a guy we've criticised quite a lot.

It's looking good for Rangers.

Dessers keeps at it, keeps going. He's missing chances but trying extremely hard to get his goal. He eventually learnt his lesson, just to get a contact and keep it going. He doesn't hide which is a good thing.

Rangers have done the exact same as Hearts. They've gone about it in the right manner. The pitch has stood up well, Rangers have created a lot and they've managed the game well.

Motherwell manager Stuart Kettlewell tells BBC Scotland: "We always look round the country, look at the upsets, and we sure as heck didn't want to be one of those clubs.

"We scored three really good goals, but there are certainly aspects that need to be sharpened up. There's stages in the game where there was nervous energy in the stadium. That's down to ourselves, although there were a lot of good performances from Alloa.

"There's often a thought process that we'll blow Alloa out the water but there's a lot more respect than that. There were aspects I wasn't happy with at all, we needed to sharpen up defensively with our organisation behind the ball, our use of the ball could be better, we can create more chances.

On double goalscorer Blair Spittal: "We know Blair has that quality. He'll be kicking himself, he'll be disappointed not to get the hat-trick. He's pitched in all season, been so consistent for us."

Airdrieonians player/manager Rhys McCabe tells BBC Scotland: "I thought we stuck to our principles and, if we'd been cuter on the counter attack, could have created more opportunities.

"We limited them to little, looked a threat throughout the game and deserved the win.

"Individually and collectively, the performances were excellent."

St Johnstone manager Craig Levein tells BBC Scotland: "We didn't start the game well and didn't get any better.

"There weren't loads of chances but we continually gave Airdrie hope. We didn't have anything that gave us the chance to gain confidence. Our use of the ball was abysmal.

"I've got to look at what we did during the winter break, because a performance like that has been unlike this group, and it's something that needs looked at."
