Billy Sharp strike sees Sheffield United increase lead to five points
Sheffield United left it late to turn their dominance into a 1-0 Sky Bet League One victory at Peterborough.
The League One table-toppers squandered a host of chances before Billy Sharp struck from point-blank range with three minutes to go for his 20th goal of the season that extended their lead at the top to five points.
Sharp pounced at the back post after strike-partner James Hanson had headed down a cross from the right. It sparked jubilant scenes among a travelling army of almost 4,000 Blades fans at the ABAX Stadium.
Chris Wilder's men had looked like drawing a blank with Hanson being denied by Posh goalkeeper Luke McGee either side of half-time.
Hanson also fluffed the rebound on the first of those occasions with Daniel Lafferty lashing a follow-up over after the second opportunity.
Hanson also headed wide late on, but then turned provider for Sharp to settle the contest in the 87th minute.
Blades goalkeeper Simon Moore was a virtual spectator. His only real task was keeping out a 30-yard drive from Marcus Maddison in the second half.
Home debutant Anthony Grant also flashed a long-range blast wide late on for a home side who were short on attacking ideas.
