Lloyd Jones scored the only goal nine minutes from time as Charlton kicked off their Sky Bet League One campaign with a 1-0 victory at Wigan.
The home side had the lion’s share of the encounter at the newly-named Brick Community Stadium, but could not make any of their chances count.
Thelo Aasgaard sent one volley wide and another free-kick over the bar, before his teasing left-wing cross was missed completely by Baba Adeeko at the beginning of the second period.
Aasgaard really should have opened the scoring when he raced through on goal, only to take too long in shooting and being dispossessed by Kayne Ramsay in the nick of time.
But the Addicks had the last laugh in the 81st minute as Wigan failed to clear a free-kick, and the unmarked Jones slotted home at the far post.
Charlton boss Nathan Jones was shown a yellow card deep into stoppage time after remonstrating with the official on the touchline, but he will care little about that, as his celebrations in front of the away support proved.
