Leyton Orient gained bragging rights in their London derby with near-neighbours Charlton thanks to a goal from Omar Beckles.

The central defender met a cross on 80 minutes from substitute Dan Agyei – who had only been the field for two minutes when he sent a ball into the box – to earn a 1-0 win.

Neither side had anything to show for their intense energy in the first half with a lack of true quality proving their shortcoming.

Orient keeper Sol Brynn kept his side on level terms before the break when he was at full-stretch to keep out efforts from Corey Blackett-Taylor and Chem Campbell, after Watford loan striker Shaq Forde had spurned a good opportunity in the third minute for the home side when he blazed over the bar following a Theo Archibald corner.

Orient improved after the interval and were rewarded with Beckles’ defining goal, although they were indebted to Brynn’s fine late save from Blackett-Taylor that protected their win.

The victory exacted revenge for the O’s defeat by the same scoreline in the opening match of the season at The Valley.
