Cammy Devlin is a bit unfortunate to earn a booking for a typically strong challenge on John Ludstram.

It's even worse for fellow substitute Calem Nieuwenhof, who is hauled off and replaced with young midfielder Aidan Denholm.

Rangers haven't been knocked out their stride by that goal.

Tom Lawrence fires a powerful drive that Zander Clark can only parry and Cyriel Dessers knocks it over the crossbar on the rebound.

The pressure continues and the Hearts goalkeeper has to save one-handed at the near post to deny Borna Barisic.

Hearts need to score in the next two or three minutes to have any chance of pulling the game back level.

Referee Nick Walsh shows Stephen Kingsley a second yellow card after Ben Davies' first contribution is to challenge the Hearts left-back.

Kingsley is adamant that he was clipped and there's a VAR check...

Rangers fans will be pleased to see Tom Lawrence make an appearance after long-term injury, with Ben Davis and Cyriel Dessers also withdrawn.

Sam Lammers, Leon Balogun and Danilo are off.

So close to a fourth for Rangers - and second for Scott Wright.

Abdallah Sima fires a low cross that the winger stabs just wide from eight yards.

Even more Hearts fans started to leave after that third Rangers goal.

They thought they could get back in this one with the Frankie Kent and Stephen Kingsley chances, but it's a mountain to climb now.

Rangers are spraying the ball around with a swagger that a 3-0 lead brings, echoing Wednesday's 5-0 win at Dundee.

We all agreed that at half-time that Steven Naismith would be the happier of the two managers. Not anymore.

Maybe Boyce can nick a goal back. It's a huge ask for Hearts to get anything, but you just have to keep going.

Two more changes for Hearts.

Liam Boyce and Cammy Devlin are on for Kenneth Vargas and Beni Baningime.

That third goal came just after Steven Naismith made two attacking changes.

Yutaro Oda and Alan Forrest were sent of for Jorge Grant and Toby Sibbick.

Those have turned out to be too little too late.

Hearts fans start heading for the exits and a fairly miserable trip back along the M8.

That third goal means this game is effectively over and it's Rangers who'll face Aberdeen in next month's final.

To think that this game was tightly poised at half-time. Three goals in 13 devastating minutes from Rangers have simply blown Hearts away.

I think Zander Clark couldn't see the ball. That was part of the problem.

Even if he had seen it, I don't think he'd have seen it. That was an unbelievable free-kick.

He's double-bluffed him.

Tavernier is a very special talent.

He just hits it so accurately with so much power and dip that it goes right into the top corner.

Hearts are under pressure again and Kye Rowles hauls back Sam Lammers as the Rangers striker is poised to shoot on the edge of the penalty box.

Booking for the Hearts centre-half and it's a dangerous position.
