St Johnstone’s four close-season signings — Keith Watson, Paul Paton, Blair Alston and Michael Coulson — all played in the 2-1 away friendly win over Glentoran in Belfast.
Watson, Paton and Alston started the match and Coulson came on as a substitute.
David Wotherspoon and Dave Mackay stayed in Scotland to continue their recovery from injuries.
Steven MacLean opened the scoring for Saints two minutes in but the home side levelled before half-time through Chris Lavery.
With nine minutes left, substitute Chris Kane beat the advancing home keeper to fire the winner from just inside the penalty box after a good turn gave him the space to shoot.
An experimental Glentoran squad gave a good account of themselves with their team boss, ex-Saint Alan Kernaghan, substituting all 11 players at half-time.
His second-half line-up included only three players with first-team experience — Elliott Morris, Calum Birney and Patrick Cafolla.
Saints are now back in Scotland to prepare for tomorrow’s away friendly against Livingston.
The Perth club open their Betfred League Cup account away to Elgin City on Saturday, then face Bradford City in a home friendly next Tuesday.
They then embark on League Cup duty again the following Saturday when Peter Houston’s Falkirk travel to McDiarmid Park.
