Morelos and Jack make theirs a double as Gers stroll it
Ross County 0 Rangers 4
Rangers ripped Ross County apart in their lopsided Ladbrokes Premiership match at the Global Energy Stadium.
On a freezing night in Dingwall, Colombia striker Alfredo Morelos got the visitors up and running in the 20th minute when he knocked in a pass from Sheyi Ojo for his 17th goal of the season.
Returning midfielder Ryan Jack scored a brace of strikes to have the Light Blues on easy street by the interval.
Morelos grabbed his second with a drive in the 72nd minute to make it 4-0 and keep Steven Gerrard's side behind leaders Celtic on goal difference.
Important games keep coming for the Ibrox men and they will go into their Betfred Cup semi-final against Hearts at Hampden Park on Sunday with further confidence.
After a hard-fought win over Motherwell at the weekend, Gerrard made five changes, with Wes Foderingham replacing injured Allan McGregor in goal, while Glen Kamara, Jack, Ojo and Morelos all came back in.
In the fourth minute, Ojo clipped the post with a right-footed shot after being set up by Joe Aribo on a swift counter-attack.
Then, 10 minutes later, midfielder Scott Arfield played a one-two with Morelos and fired in a right-footed drive which was pushed round the post.
The opening goal came at the end of a slick move involving Aribo and Ojo, who slid the ball across goal for Morelos to net.
The Ibrox side grew in confidence and their second goal came in the 29th minute when Jack pounced on defender Liam Fontaine's clearance and curled the ball home.
Jack's second goal was with a similarly well-placed drive after good work by Aribo and Arfield.
Aribo rattled the post from eight yards as Rangers started the second half with as much purpose as they had finished the first.
Jack then fired a left-footed effort from 20 yards wide as the Ibrox men kept the pressure on.
In a rare Ross County attack in the 68th minute, Ross Draper's deflected drive from distance took a deflection and wrong-footed Foderingham but rebounded off the post.
Rangers ran up the park moments later and Morelos hammered in a fourth from 10 yards before immediately making way for Jermaine Defoe, with the visitors keeping a tight grip on the game until the end.
