Auger-Aliassime then held his nerve to serve out for the set and give Team World a huge advantage. Djokovic then got off to the worst possible start in the second set as the Canadian got the early break.
The 35-year-old broke back midway through the set with a tiebreak needed to settle the score. But Djokovic never looked relaxed or in control with Auger-Aliassime picking up his first win over the Serbian.
That victory also gave Team World their first lead of the Laver Cup and put them one win away from lifting the trophy for the first time.
