Ireland 28-17 Argentina
Ireland opened their home run of autumn internationals with a hard-fought win over Argentina at the Aviva Stadium in Dublin.
Despite the victory, the Irish looked slightly disjointed, and their ill-discipline at the breakdown proved to be a theme of the first 40.
Early in the match, it allowed Sanchez to kick the visitors into a 2nd minute lead, before his side had even got their hands onto the ball.
The Ireland pack soon mauled their way over the line in reply, and although there was no clear view of the grounding, they dominated the resulting scrum, and Kieran Marmion was able to dart over from close range for the game's first try in the 9th minute.
However, further poor Irish play at the breakdown allowed Sanchez to kick his side back into a 12th minute lead, before the South Americans scored a superb try in the 18th minute.
It was Delguy who finished easily in the right corner after powerful running from outside centre Orlando, who broke through several tackles in midfield to slice open the Irish defence.
With 25 played, Ireland racked up a series of advantages as the Argentine defenders started to lose their composure, with the referee threatening to show a yellow card. The pressure eventually told as Bundee Aki found a gap to snipe over from 8 yards for the home side's second try.
The penalties kept coming; Sanchez and then Sexton each additional slotted kicks, and the first half ended 15-14 to the men in green.
The second period continued as much of the opening had passed, with sloppy defence from both sides first allowing Sanchez to nail another penalty in the 43rd minute, before Sexton replied in the 58th to restore the narrow Irish lead.
Ireland finally put some daylight between the 2 teams with 66 on the clock as replacement scrum-half Luke McGrath collected a quick pass from the back of the scrum and nipped over near the posts from the 5-metre line.
As the match wore on, any chance of an Argentine revival began to fade, and Sexton nailed a 76th minute penalty to make it 28-17.
