A 4-1 success at sixth-placed St Saviour's (16 points), thanks to goals from Richie Jones (2), Mark Swann and Paul Smith, puts them one point clear at the summit on 21 points, although the Oilmen have a game in hand.

Keith Williamson (penalty) and James Curtis netted for the basement dwellers but Jamie Fitzpatrick, Ian Martin and John Farrell (penalty) secured the points for the Motormen.

Princes Rovers (26) extended their lead at the top of The Holiday Inn Ellesmere Port Division Two by a point with a 3-1 win over fifth-placed RJS Sir Robert (16).
