Kurt Willoughby tries one from range but it trickles into the grateful arms of Jack Butland.

Neil McCann
Former Rangers winger on BBC SportsoundHe's smashed that into the top corner.
It's all about Todd Cantwell though. He just lifts that into the box and there's no messing about from Silva.
GOAL! Rangers 2-0 Ayr Utdpublished at 19:08 Greenwich Mean Time 10 February
Fabio Silva
And those 15 minutes will feel a lot more comfortable now.
Todd Cantwell dinks a ball to the back post, it's eventually hacked off the line, but Fabio Silva picks it up and finishes emphatically on the spin.

Ryan Stevenson
Former Ayr United midfielder on BBC SportsoundAyr are going to have to get bodies forward and try and carve out some opportunities.
It leaves them more susceptible to the counter, but they have to go for it at some point.

Jack Butland flaps at it, gets nowhere, then the ball just kinda hits Sean McGinty and runs out.

Neil McCann
Former Rangers winger on BBC SportsoundHe should score. It's a great delivery from James Tavernier but Fabio Silva doesn't get enough purchase on the header.

Fabio Silva heads a James Tavernier cross off target.
Should probably do better.

Ben Dempsey will be seeing this chance in his dreams for weeks.
What an opportunity to level the game.

Curse of the co-commentator.
Just after receiving that praise, Sean McGinty is in the book as he tugs back Fabio Silva.
If that's any nearer to the goal, the Ayr defender is in big bother.

Former Rangers winger on BBC SportsoundSean McGinty has been absolutely superb. The Ayr centre-half had a really good game today.

Neil McCann
Former Rangers winger on BBC SportsoundIt's tough for Ayr United with the quality Rangers have just brought on. It's a luxury for them.
Oscar Cortes, for me, was the best player in the first half.

Far better from Rangers as they push for a second.
Scott Wright has a dangerous shot blocked before James Tavernier heads just wide at the back post.

Just over half an hour to play and Ayr are right in this as they clear the ball in a bit of a panic.

Ayr work a deep free-kick well and Connor Goldson has to slide to deny Logan Chalmers.
Rangers break then about a million tackles fly in from the away side before a foul is eventually given.
