Danny Hylton's second-half penalty secured Oxford a 1-1 draw at Southend.Hylton won the spot-kick after being adjudged to have been brought down by Shrimpers centre-back Luke Prosser.And he confidently stroked the 67th-minute penalty into the bottom left-hand corner for his fourth goal of the campaign.Southend had earlier taken the lead in the 36th minute with Jack Payne netting his third goal in two games.The young midfielder was found inside the penalty area by Conor Clifford and drove an impressive low, right-footed shot into the corner of the net.Oxford hit back strongly with Hylton having a well-struck volley smothered by Shrimpers goalkeeper Daniel Bentley at the start of the second half.Hylton then had a curling effort impressively tipped over by the young Southend goalkeeper.But Hylton's penalty ensured the game ended all square, despite nine minutes of injury time being played.
