Fans have to go back to BBC's late 1940's footage and Jackie Kyle for something like this; indeed there is a 1948 Grand Slam try against Scotland on YouTube writes One F in Foley

Let's hear it for the boy! Sam Prendergast's second-half try was absolutely sensational on Friday.

Not just good, not just the best out-half's try this season, not just of the Irish professional era.

Take it as read: neither Ronan O'Gara nor Johnny Sexton who could do so many things so well, had the 60m-dash pace, even if they had the vision.

So not just the best Ireland no10 try of the modern era, it is the best captured on colour TV sets.

Fans have to go back to BBC's late 1940's footage and Jackie Kyle for something like this; indeed there is a 1948 Grand Slam try against Scotland on YouTube.

Prendergast's try on Friday night began with Casey, some 40m out left going to the blindside to open up the pitch and where they commit three players - Joe McCarthy, Andrew Porter and Tadhg Beirne - to a ruck.

Ronan Kelleher, nearest, and Sean Jansen, a little further across, look for the next pass off the base, and the scrum-half chooses the latter.

Jensen rushes five/six steps towards the line before passing off his left-hand to Prendergast who has the Argentina 'D' coming up in a line.

The out-half spots the gap and straightens slightly before throwing his trademark hands-low 'dummy' and knifes though a gap that has Puma no6 Juan Martin Gonzalez as one of it's pillars

(TV calls this as Prendergast spotting a 'mis-match', it is no such thing, JMG is at Saracens, one of the best wing-forwards in The English Premier.)

Once through the gap, Prendergast did what O'Gara and Sexton could only watch at the Olympics: the application of sprint speed as he scorched 40m to score.

The grin on Andy Farrell's face, the 'I told you so' to those who doubted his fast-tracking, was plain to see:

"That is something that we've seen from Sam in his earlier days, his running threat was always prevalent in his game." said the coach.

"You've certainly seen that at the start of this year with him as well. He's got it in his game; he's strong, he's got a good, strong fend, and he's quick.

"He's smart because he plays with the ball in front of him in two hands. People don't know whether he's going to pass or run. He's certainly a threat at the line."

There's also the vision there - that's a flanker he gets by initially; it's not like spotting two props or a gaggle of fatties in the gap.

"If you look at the try, the reason for the try is that everyone's in it.

"If you've got options at the line and people are running genuine lines, then defences get pulled around, and he's smart enough to see that and show and go, and off he goes.

"It looks like it's Sam's try, but it's a good team try. There's five lads around him who are doing a great job."

Man of the Match Hugo Keenan says there is even more to come from Prendergast.

"I think we all know Sam's capabilities, how good he can be, we see it every day in training and I suppose it is just about delivering on it consistently now.

"He worked hard during pre-season, he is ambitious. He knows where his weaknesses were and he's worked on those. He has put on a bit of size and he's kept that bit of pace.

"He is playing great rugby and he is someone I enjoy playing with because he is so skilful.

"He takes it to the line, he's got a bit of a threat himself but he has also got an unbelievable passing and kicking game, so it's great to see him go well."
