Rangers cut the deficit behind cinch Premiership leader Celtic to six points with a one-sided 2-0 win over Dundee United at Ibrox but the title remains on course for Parkhead.
Giovanni van Bronckhorst rang the changes following Thursday's thrilling Europa League semi-final win over RB Leipzig and it took until the 55th minute to get the breakthrough when skipper James Tavernier scored from the spot for his 17th goal of the season.
Substitute Amad Diallo added a second in the 78th minute to reduce the gap behind Celtic with two fixtures remaining, but Rangers have a vastly inferior goal difference of 20 which makes the Hoops overwhelming favourites to reclaim the title.
