At St. James' Park
Newcastle United Under-18s 4 (Quinn 3, Armstrong)
Sunderland Under-18s 0
Jonathyn Quinn hit a clinical hat-trick as Newcastle cruised into the fifth round of the FA Youth Cup with a 4-0 derby win over Sunderland at St. James' Park.
The Ashington-born striker, wearing the number nine shirt, was joined on the scoresheet by Adam Armstrong as United made it three wins out of three over their local rivals at this level in 2013/14.
A crowd of 3,501 were treated to a superb second half showing from the Magpies, with Quinn forcing a good save from Maksymilian Stryjek inside the first five minutes.
Greg Olley then shot well wide for Newcastle before Quinn cut inside but saw his shot easily saved and Aarons' looping header dropped over the bar.
Thomas Robson had the visitors' only shot on goal in the opening 45 minutes but, after a strong run, his effort was weak and comfortably saved by Freddie Woodman.
And in the 44th minute, Rolando Aarons jinked into the box before cutting the ball back for Quinn to stroke home.
The second half started with Armstrong shooting straight at Stryjek but the Sunderland keeper was to blame as United made it 2-0, dropping a routine cross from Olley and allowing Quinn to tap home from six yards.
Soon afterwards, from Aarons' deep cross, Quinn headed back across goal for Armstrong to prod wide, then the England under-17 frontman made space in the box but blazed off target.
But after a superb darting run from Jamie Sterry and an accurate low delivery, Quinn completed his hat-trick then Armstrong capitalised on a poor backpass to make it four.
Sterry saw a shot deflected wide and Aarons and Armstrong also came close late on, with United facing either Stoke City or Derby County in the last 16.
