Garstang exited the FA Vase at the first qualifying round stage after a 2-1 loss to Sunderland West End.
Defeat came despite a much improved performance under the new management team of Richard Cookney and Mike Hartley.
The hosts started the brighter, and for the first quarter of an hour, they were in total control of the game.
Despite having most of the possession, Garstang could not create any clear chances and were restricted to some long-range efforts from Jack Swindlehurst.
After this the visitors came back into the game and Will Kitchen was forced to make a smart save at his near post.
However, Garstang fell behind on 22 minutes when a corner was headed home by Daniel Martin.
Although Sunderland were in the ascendancy, Garstang weathered the storm and again took control with Alex Hay seeing a header well saved and Andrew Murphy’s effort cleared off the line.
It was against the run of play that Sunderland doubled their lead when, after Kitchen made a save, Kieron Martin netted the rebound.
Garstang pulled a goal back just before half-time when a corner fell to Hay, who stabbed the ball home to make it 2-1.
The Riversiders started the second half on the front foot with Murphy having a shot saved and Alan Coar unable to turn the ball home from a tight angle.
Murphy and Jake Salisbury saw plenty of the ball as Garstang sought an equaliser but only a point-blank save from Kitchen prevented Sunderland from making it 3-1.
At the other end, a flying save kept out Murphy’s free-kick, and although Garstang put plenty of balls into the box, nothing seemed to fall their way as Sunderland saw out the game for victory.
