Leyton Orient scored four goals in 23 second-half minutes after trailing at the interval to claim a 4-3 win against Barnsley and move into the play-off places.

Stephen Humphrys scored in the 11th and 19th minutes to seemingly put the Tykes in control but a stirring second-half performance from the hosts saw goals from Ethan Galbraith, Charlie Kelman, Sean Clare and Omar Beckles earn them the points.

Galbraith had reduced the deficit in the 51st minute after exchanging passes with Jamie Donley but Barnsley restored their two-goal advantage after 65 minutes when Davis Keillor-Dunn seized on a Keiren Flavell goal-kick .

Within three minutes, Donley picked out Kelman for the striker to net his 20th league goal of the season as Orient’s fightback intensified.

Kelman turned provider after 71 minutes when he laid the ball into the path of substitute Clare and he calmly placed the ball wide of Flavell for the equaliser and the O’s comeback was completed three minutes later when defender Beckles stabbed the ball home from a corner.
