RANGERS cruised into the fifth round of the William Hill Scottish Cup with a drubbing of League One Cowdenbeath.
Martyn Waghorn notched up the second hat-trick of his Light Blues career through a fine strike and two penalties. It also saw the 25-year-old move onto 25 goals for the season with three months of the campaign still to play.
Captain Lee Wallace put Gers ahead within 20 minutes before Barrie McKay added a second, a goal capping off an impressive performance from the 20-year-old. The visitors did have their moment at 2-0 when Dean Brett curled a brilliant free-kick into the top corner but Rangers responded to close the game out.
5 - 1
