Manager Tom Hendrie parted company with Craigroyston following their 7-2 Central Taxis Premier Division defeat by Tynecastle.
Former St Mirren boss Hendrie and his assistant Gary Sutherland have left after the St Mark’s Park side conceded 17 goals in all competitions and still seek their first win of the season.
Hendrie took the reins last November and guided Craigroyston to an impressive third-place finish and a League Cup final which they lost to Hibs EOS.
But they have made a torrid start to the new campaign, hampered by the inability to attract new players.
Things could have been all so different at Fernieside on Saturday after they took a third-minute lead through Jason Young. But, within the space of 15 minutes, Tynecastle were ahead through Dean Cummings and a penalty by Jamie Devlin.
Former Tynecastle player Matthew Costello equalised with a header from a Chris Hendrie corner on 21 minutes, but in a devastating second half, Devlin scored another three goals while further strikes by Cummings and substitute Brendan Edwards rubbed salt into the wounds.
Craigroyston will advertise the vacant manager’s post and interested parties are asked to contact club secretary Jim Sivewright on 07817 530152.
Leith Athletic’s fine start to the season continued with a 5-2 victory over Spartans EOS at Meadowbank 3G.
Derek Riddel’s side took a 3-0 interval lead thanks to a quickfire Kevin Murray hat-trick inside the first 25 minutes.
Spartans EOS did threaten a second-half comeback through goals by Lucasz Rusin and a David Stewart penalty, but the game’s decisive moment came on 70 minutes when Leith winger Christopher Barrie was upended in the area by defender Keith Boyes and Murray converted his second penalty of the afternoon.
A Stephen Baigan header ten minutes from time sealed the three points for Athletic, but despite another impressive win, manager Riddel is remaining cautious.
He said: “Confidence is high at the moment and while we’ve started well, the guys need to remember that it’s a long hard season.”
Spartans EOS manager Alex Cunningham, whose side suffered their first defeat of the season, said: “The penalty really knocked the fight out of the players.
“It was a stupid penalty to concede because we had got it back to 3-2 and then anything is possible.”
Lothian Thistle Hutchison Vale began the defence of their Premier Crown with a 4-1 victory over a depleted Coldstream at Saughton Enclosure.
Goals by Sean Wringe, Kevin Keane, a debut goal by Ryan Malcolm and a Willis Hare penalty secured an impressive opening win. Coldstream’s solitary goal came from John Crawford with the visitors only able to name one substitute.
Easthouses Lily defeated Stirling University 4-0 at Newbattle Complex, their goals coming from Paul McDermott, Kenny McMillan, Darren Robertson and John Hunter.
