Jonny May scored his 10th international try as England claimed a record victory over Australia.
Leicester Tigers winger May latched on to Danny Care’s kick to score England’s third try in their 30-6 win at Twickenham on Saturday afternoon.
Youngs helped to make Elliot Daly’s opening try. The scrum-half’s clearance from inside his 22 bounced fortuitously for Daly to hack ahead and touch down.
Jonathan Joseph scored England’s second, latching on to Care’s kick to slide over before another Care kick set May on his way to the tryline.
And May returned the favour for Care to score the fourth and final England try in the closing moments. May gathered loose ball on halfway and offloaded out of Marika Koroibete’s tackle for Care to score at the corner.
Luke Hamilton, meanwhile, made his debut for Scotland in a thriller against New Zealand at Murrayfield.
Tigers back rower Hamilton replaced Hamish Watson in the 26th minute of Scotland’s epic 22-17 defeat to the World Champions.
Hamilton made a big impression with a series of strong carries before his game was ended by a leg injury nine minutes into the second half, when he was taken from the field on a medical buggy.
Jonny Gray and Huw Jones crossed for Scotland, while Finn Russell landed two conversions and a penalty.
But the All Blacks ensured victory with tries from Codie Taylor, Damian McKenzie and Beauden Barrett, with the latter also kicking seven points.
Elsewhere, Afa Pakalani won his third cap for Tonga but could not prevent them losing 39-6 to Japan in Toulouse.
Japan scored five tries, with Lomano Lemeki crossing twice, and Amanaki Mafi, Michael Leitch and Kenki Fukuoka all dotting down. Yu Tamara kicked four conversions and two penalties, while the Tonga points came from two Tane Takulua penalties.
