Seamus Conneely's goal sent Accrington back to the top of Sky Bet League Two with a 1-0 win at 10-man promotion rivals Mansfield.Conneely struck on the hour mark after Mansfield had wasted two good chances following Mal Benning's 13th-minute dismissal for a high tackle on Billy Kee.It left the Stags without a league win over Stanley in 14 attempts and new boss David Flitcroft without a victory in his first five games in charge.In an ill-tempered first half, Mansfield started well and Lee Angol had a vicious shot tipped over after only two minutes.After losing Benning the hosts almost stole the lead after 33 minutes as Aaron Chapman turned over a powerful Rhys Bennett header and Angol volleyed wide from the corner.The home side missed another sitter in the 50th minute as Kane Hemmings side-footed wide from six yards from a low Hayden White cross.Stanley punished them after 60 minutes as Conneely was left unmarked from a Sean McConville corner to send a six-yard header past Conrad Logan to steal the points.
