Dundee Manager Neil McCann made four changes Steven Caulker, Glen Kamara, Paul McGowan and Benjamin Kallman replacing Genseric Kusunga, Lewis Spence and Craig Wighton.
Reports and highlights I've seen and read say that Dundee played some neat football without having too many clear cut chances in the first half. Kallman had a decent effort which went wrong side of the post. The Perth Saints did force Jack Hamilton into a few saves when they broke with pace.
Early into the second half and St Johnstone took the lead when Dundee lost the ball in midfield and Tony Watt was sent clear to score. Dundee tried to get back into the game but failed, the only real chance was near the end a header from Moussa which was too close to the keeper.
Sadly time ran out for the Dark Blues and that's three defeat in the league now, we need to pick ourselves up for the vital game at home to Motherwell next Saturday.
Dundee: Hamilton, Curran, Meekings (c), Caulker, Ralph, Madianga (Moussa 81), Kamara, McGowan, Mendy (Ngwatala 61), Nabi (Wighton 86), Källman. Unused Subs: Parish, Kerr, Jefferies, Spence.
Att: 4,259.
