The Waratahs are facing a huge Super Rugby test against the unbeaten, new-look Melbourne Rebels after their undefeated start to the season was shattered in a 38-28 loss to the Jaguares.
The match in Buenos Aires yesterday was reminiscent of so many in the Waratahs' abysmal 2017 campaign, in which they frequently conceded sizeable leads and found themselves chasing the game.
The Jaguares scored four tries in the opening quarter, including the first within 17 seconds, to rush to a 22-0 lead.
Tries either side of the final hooter from replacement forward Nick Palmer and fullback Israel Folau, added a veneer of respectability to the scoreline, but had no impact on the result.
With one last-gasp win over the Stormers, a draw against the Sharks and now a loss, the Waratahs are already nine points adrift of Australian conference leaders the Rebels, who they host on Sunday afternoon.
