Sunderland West End endured a disappointing first day of the season in the TWR Bifolds Wearside League.
Right on the stroke of half-time, David Keithley lifted their spirits with a close-range effort.
But Boldon CA had the better of the second 45 minutes and ended 2-1 winners courtesy of captain Jack Lawton, who produced a cool finish after controling a long ball from the keeper, and Dominic Mossa, who held off his marker to fire home from a tight angle.
West End keeper Chris Smith made an outstanding save at 1-1, leaping acrobatically to tip over a fierce strike.
West End were reduced to 10 men before Mossa grabbed the winner.
Boldon boss Paul Mossa said: “Obviously I’m delighted with the performance and the result.
“Sunderland West End are a very good team, but we had too much for them. The togetherness of the squad and the will to do well is clearly evident at the club. However, this is just one game with many more to come.”
West End are back in action at home to Prudhoe Town on Wednesday night.
Coxhoe Athletic twice rallied to see off newcomers South Shields Reserves 3-2.
A brace from Jack Donaghie encouraged the Mariners in their first competitive match, but Tom Maddison and Kyle Morris levelled and, in added time, Morris sent his side home jubilant as he netted the winner.
Stokesley SC were relegated from the Ebac Northern League Second Division last term and earned a point on their return to the Weatside League.
Seb Hanratty was an early scorer for Stokesley, but Richmond Town turned the tables thanks to strikes from James Coatsworth and Scott Ryan. With only five minutes left, Jordan Rivis earned Stokesley a point at 2-2.
