The Ireland Under-20s lost for the first time in this year’s Six Nations as they were edged out 19-14 by a powerful England side at Donnybrook.
The visitors grabbed second half tries through backs Piers O'Conor and Joe Marchant, as they erased Ireland's 9-6 interval lead.
Three penalties from Ross Byrne had Nigel Carolan's youngsters in front and a smashing Stephen Fitzgerald try cancelled out O'Conor's effort. But England decisively hit back with a James Mitchell penalty and Marchant's fifth try of the tournament.
Ireland had their chances, particularly during a free-flowing first half, and will be disappointed not to have converted them as the English now join them at the top of the Championship table with two wins from three.
England scrum half Mitchell missed his opening shot at the posts, dragging a penalty to the left and wide, while Byrne did likewise as the tricky wind pulled his kick away to the left.
The Irish out-half, who produced a man-of-the-match performance against France, almost teed up an opportunist opening try for Fitzgerald. Byrne took a penalty quickly in the English 22, hanging up a cross-field kick from right to left and the inrushing winger just failed to hold onto it in sight of the try-line.
Having struggled for possession early on, Ireland were beginning to grow into the game and they went ahead in the 12th minute when Byrne fired over a right-sided penalty. A classy defence-splitting break from man-of-the-match Garry Ringrose gave Ireland further momentum, however a poor pass from the supporting Billy Dardis led to Jack Owens knocking on out wide.
Byrne rewarded his side for a sustained period of pressure by slotting a straightforward 21st-minute penalty, before Mitchell quickly replied for the reigning Junior World champions at the other end.
The Irish attack clicked into gear shortly afterwards, with centre Ringrose again at the heart of it. He chased down his own kick near the right corner, instinctively flicking a pass behind his legs to his support. Sam Arnold, excellent prop Jeremy Loughman, Zack McCall and Lorcan Dow all carried up close to the line, but the physical English defence held out.
Nonetheless, the visitors were still leaking penalties and flanker Will Owen saw yellow as he killed the ball following a Dow pick and go. Byrne split the posts from the resulting kick, only for Mitchell to cancel out those three points and with number 8 Dow soon sin-binned, Ireland were fortunate to avoid the concession of a try as full-back Aaron Morris elected to go alone rather than pass outside him.
However, Ireland endured a frustrating start to the second half as Morris' replacement at full-back, O'Conor, beat Owens to a garryowen and with the home defence caught napping he ran 60 metres unopposed to touch down in the left corner.
Mitchell was unable to convert, but Ireland, with flanker Josh Murphy setting the standard in terms of work-rate, showed good character to answer back some 10 minutes later.
A barnstorming initial break from hooker McCall got Carolan's side firing again, Byrne's inviting pass then put Ringrose into space and he cleverly drew in a covering defender to send Fitzgerald clear to score in the right corner.
The home crowd groaned as Byrne's conversion attempt came back off the left upright, leaving Ireland with a 14-11 lead. England used their greater size up front to force the levelling penalty, putting pressure on the Irish scrum and Mitchell mopped up the three points from the kicking tee.
There was further tension after Byrne missed a penalty with 15 minutes remaining and with the English forwards growing in influence, the platform was created for Marchant to step inside Ringrose's attempted tackle and dot down to the right of the posts.
Mitchell was off target with the conversion, though, and England had to knuckle down in defence as lively replacement forwards Conan O'Donnell and Nick Timoney made some big carries to get Ireland back within sight of the whitewash.
Ringrose earned a penalty for a high tackle on the left, but England defended well from a couple of close-in lineouts and a crucial knock-on gave them a relieving scrum and there was no way back for the hosts.
