Walsall moved above Burton Albion to lead the way in League One following a 2-0 victory over Jimmy Floyd Hasselbaink's men in a top-of-the-table clash on Saturday.
A first career goal from 19-year-old Liam Kinsella put the hosts ahead after 36 minutes, but Burton were denied an equaliser shortly after half-time when they hit the crossbar.
The three points were wrapped up by the hosts in second-half stoppage time, though, as Tom Bradshaw converted from the penalty spot, sending Walsall to the summit at the expense of their guests.
At the other end of the table, Fleetwood Town and Oldham Athletic suffered defeats to Coventry City and Scunthorpe United respectively.
Gillingham moved to within a point of Walsall following their 3-1 win away at Chesterfield, but Bury missed the chance to join the top two on 25 points as they were held at home by Wigan Athletic.
Southend United moved into the play-off places as James Pigott's goal proved enough for them to consign Port Vale to a second consecutive defeat, while Crewe Alexandra remain bottom despite picking up their second win of the season at Barnsley.
Elsewhere, there were victories for Sheffield United against Rochdale, Shrewsbury Town at home to Colchester United and for Peterborough away at Swindon Town.

Oxford United also took their points tally for the season up to 23 with a 1-0 triumph over AFC Wimbledon at the Kassam Stadium.
