Scott Sinclair scored a hat-trick and Scott Brown netted his first goal in two years as holders Celtic eased past St Johnstone and into the quarter-finals of the Scottish Cup.
In the third meeting of the Premiership sides in 12 days, Brendan Rodgers’ men were two up inside nine minutes thanks to Sinclair and Brown’s stunner.
James Forrest, then Sinclair, scored within two minutes of each other just after the break. And Sinclair completed his hat-trick when he latched on to a deflection in the St Johnstone box.
Celtic have now won 24 consecutive domestic cup games under Rodgers as they aim for an unprecedented ‘treble-treble’.
This season, in six cup ties, they have scored 16 and conceded just once.
Celtic earned hard-fought 2-0 wins in each of the previous two meetings, both in the league, but this time the Perth side offered little, apart from a Chris Kane effort that Scott Bain saved.
Tommy Wright’s side struggled to deal with Oliver Burke, who burst into space and crossed for each of Sinclair’s first two goals.
Brown lashed high into the net on the eve of the second anniversary of his last goal – in a 6-0 thrashing of Inverness CT in the same competition.
And Forrest made no mistake from a slight angle after Jonny Hayes’ marauding run.
