The Askern clinched the Doncaster Sunday Alliance League Division One title with a game to spare after romping to a 9-1 win over second-bottom Leopard.

The Division Two title race looks set to go down to the wire.
Leaders Rycroft Rovers retained their two-point lead after receiving a walkover against FC Wadworth.
Legion Park Rangers kept the pressure on with a 9-1 win at Schoolboy Norton.
Scott Henderson claimed five of the Legion goals with Reese Pegden and Mark Ridley both bagging a brace.
Balby Athletic effectively wrapped up the Division Three title after beating Newlands (William Amps) 6-1.
The Railway did all they could to deny them by beating White Hart (Askern) 2-0 in their final game.

Rhino’s, who are a point clear with a game in hand, also boast a slightly better goal difference.
Championship leaders Rossington United ended their campaign on a winning note when beating Tank (Stephen Phillips) 4-1.

They need to pick up at least a point in their last game to ward of the challenge of Carpenters Arms.
