Robins rock Posh

Substitute Jermaine Hylton hit Swindon's second-half winner to keep alive their fading hopes of automatic promotion with a 1-0 victory against Peterborough.Hylton, signed from non-league Redditch United in January, replaced Andy Williams, who crashed a hotly-disputed first-half penalty against the crossbar.It was the 21-year-old's maiden league goal and at the very least it cemented the Robins' spot in the play-offs.Hylton emerged from the bench in the 68th minute and scored almost immediately - Jon Obika teeing up the chance after neat approach play by John Swift and Harry Toffolo.Without a goal in four games, Peterborough will consider themselves unlucky to have suffered a third defeat either side of Easter.Posh had a good shape and worked hard, but their efforts in the final third let them down.Marcus Maddison missed a good chance two minutes into the second half, while caretaker manager Dave Robertson was unhappy that referee Andy Davies turned down a late penalty appeal when Conor Washington appeared to have been pushed over.
