Callum Davidson said St Johnstone let their supporters down after slipping to a fifth straight defeat.
An abysmal first half had the Perth side - who were on home soil - trailing 3-0 against Livingston and, while there was a slight recovery, the damage had well and truly been done.
Saints remain eighth in the standings following the painful 4-2 defeat, although recent results and performances make this a potentially very slippery slope and especially with tough games on the horizon.
