Worcester trio Matt Cox, Greg King and Miles Benjamin all featured as England opened their IRB Under-19 World Championship campaign with a hard-earned 20-12 win over Samoa.
Back row Cox played the entire game while King and Benjamin climbed off the replacements bench as England came from behind to claim a crucial opening victory.
London Wasps pair Hugo Ellis and Joe Simpson supplied the tries. Full-back Alex Goode added two conversions and two penalties while the Samoans relied on the boot of full-back of Titi Jnr Esau for their four penalties.
Meanwhile, Warriors youngster Ollie Frost has been added to the England Under 18s Six Nations Festival squad.
Scrum-half Frost has replaced Leicester Tigers player Ben Youngs, who has been released to join Leicester's senior 1st XV squad. Frost joins Worcester team-mate Graham Kitchener in the England set-up.
Frost has already pulled on an England shirt this season, running out for the England U18s AER squad which took on Scotland. He was also involved in the England U16s squad last season.
The England Under 18s Six Nations Festival squad kick-off their campaign on Easter Sunday against Scotland. England will then take on Wales and Ireland on April 11 and April 14 respectively in the round robin tournament.
The squad is drawn from players in the Rugby Football Union's Junior National Academy and Under 18s Conference Squad, which is fed by the 14 RFU regional academies.
Niall Annett and Phil Dowson are among three changes to the Warriors starting line-up for their trip to Franklin's Gardens to take on Northampton Saints in the Aviva Premiership this Saturday (kick-off 3pm).
