Sheffield Wednesday produced a five-star display away at Hartlepool to move a point ahead at the top of League One.
Neil Mellor was the star as he scored one and made another two, with the Owls now 7/2 to be crowned champions at the end of the season.
The result also means that Hartlepool are still searching for their first home victory.
Craig Mackail-Smith continued his fine record of scoring against Plymouth with a second-half brace to hand Peterborough a 3-0 victory at Home Park.
The forward scored three times against Plymouth last season and proved their nemesis again, while Aaron Mclean added the third to seal the win.
Charlton began the day joint top of the division but now sit eighth after being defeated 3-1 at Huddersfield.
They were always facing an uphill struggle from the moment Jordan Rhodes gave Lee Clark’s men a first-half lead and had little to smile about despite substitute Matt Fry’s last minute consolation.
Charlton are now 14/1 to win League One this season, with Huddersfield still well fancied at 4/1.
Oldham were another of the early season pace setters but they also lost some ground on Sheffield Wednesday by being held to a goalless draw at home by Yeovil.
Southampton remain the 5/2 favourites to finish at the head of the League One standings at the end of the campaign after claiming their first victory of the season against Bristol Rovers.
Rickie Lambert came back to haunt his former club with one of the goals in the 4-0 success.
Arguably the game of the day saw Notts County claim a 3-3 draw at Bournemouth and they are 40/1 to win a league for the second season in succession. See the whole League One winners market.
