Scottish Cup: Celtic thrash St Johnstone, Hearts KO Talbot
Scott Sinclair scored a hat-trick as Celtic's trophy defence continued.
Celtic 5-0 St Johnstone
Celtic powered into the quarter-finals with a demolition of St Johnstone at Celtic Park.
The holders had an explosive start as they went two goals up in the space of nine minutes with Oliver Burke setting up Scott Sinclair for the opener before Scott Brown fired in a stunning long-range shot.
St Johnstone couldn't find an opportunity to get back into the game but Tommy Wright brought on Tony Watt at half-time in the hopes that the striker could conjure something against his old side. But it was Celtic who found their attacking groove with another quick-fire double.
James Forrest scored the third in the 52nd minute and two minutes later Scott Sinclair doubled his tally, set up by Burke again.
Odsonne Edouard and Timothy Weah were introduced from the bench but the final goal came from Sinclair, with the Englishman firing a shot into the bottom corner to seal his hat-trick.
Hearts 4-0 Auchinleck Talbot
Auchinleck Talbot took the headlines in the last round when the Juniors side beat Ayr United but they were no match for Hearts at Tynecastle.
Craig Levein named a strong side, to ensure there was no upset and saw his players secure progress with plenty to spare.
Captain Christophe Berra put the hosts ahead ten minutes in, heading past Andy Leishman from an Olly Lee free kick.
And they doubled their lead through Demetri Mitchell, whose low shot from the edge of the box took a deflection on its way into the Talbot net.Mitchell then set up the third just before the break, sending a ball across goal that Steven MacLean met to knock past Leishman.
Teenage striker Aidan Keena wrapped up the scoring in the final moments, jinking past two Talbot players before smashing home a powerful finish.
Aberdeen 4-1 Queen of the South
Derek McInnes' Aberdeen produced a strong second-half performance to down Queen of the South and march on to the quarter finals.
There were few chances for either side in the first half but McInnes made a decisive change at the break, introducing Niall McGinn for Stevie May to immediate effect.
The ball fell nicely for McGinn just inside the box and he curled his shot home to put his side ahead.
But Queens weren't to be written off and their talisman struck back instantly. Stephen Dobbie carried the ball from deep and unleashed a perfect shot that found the top corner from 30 yards to seal his 38th goal of the season.
Just after the hour, the Dons were back in front, Andy Considine the scorer from a McGinn set piece. And the Northern Irishman set up the third, sending in a corner that Sam Cosgrove headed in.
And Aberdeen wrapped up the scoring on 73 minutes when Andy Stirling was perhaps unfairly judged to have handled in the box. Cosgrove took penalty duties and bagged his second of the game.
