France 31-37 Ireland
Jack Murphy was a perfect seven-out-of-seven from the kicking tee as Ireland scored four tries and got their Under-20 Six Nations campaign off to a dream start in Aix-en-Provence.
Andy Farrell's senior side had shown them the blueprint with their famous win at the Stade Velodrome on Friday night and Richie Murphy - dad of Jack - saw his troops follow suit to make it a bumper weekend for Irish rugby.
The two sides traded blows throughout in a highly physical encounter in front a of a raucous French crowd.
Danny Sheahan bulldozed over in the fifth minute to put Ireland ahead, with Murphy clipping over the conversion. France were level seven minutes later when captain Mathis Castro-Ferreira drove over with Tom Raffy - who was also flawless from the tee - levelling the game.
Brian Gleeson's try had Ireland back ahead after 25 minutes but that man Castro-Ferreira quickly equalised. A Murphy penalty from 40 metres in first-half injury time edged Ireland ahead at the break, 17-14.
Patrick Tuifua's superb Raffy-converted try gave France their first lead of the game, 21-17, eight minutes into the second period. The hosts then had Gregoire Arfeuil sin-binned though and Ireland took immediate advantage with Hugh Gavin's try and Murphy's conversion putting the visitors back in front, 24-21.
Raffy's well-struck penalty levelled the game at 24 apiece, before Finn Teacy and French substitute Mael Perrin exchanged tries. All square again, 31 apiece.
It was left to Murphy to nail the go-ahead score from a penalty after 77 minutes and, when captain Evan O'Connell got a hand on a crucial French line-out, Ireland held possession and sealed victory with the last kick of the game, a close-range Murphy penalty.
