OLDHAM gave manager Steve Robinson the reaction he hoped for as they knocked WIGAN out of the EFL Cup first round.
Wigan won the League One title last term while Oldham just managed to stay up and Robinson’s men lost 3-0 at Millwall in Saturday’s opening game of the season, when the new boss fielded 10 debutants.
But they bounced back on Tuesday night to claim a 2-1 victory over their local rivals, who themselves lost 2-1 at Bristol City on Saturday.
Ryan Flynn cut in from the left before sidefooting inside the far post to give Oldham an 18th-minute lead, only for Will Grigg to level 16 minutes later with a close-range volley.
But Wigan had Jake Buxton get sent off in first-half stoppage time and the hosts took advantage late on, Josh Law playing a one-two with Flynn before poking in the match winner.
ROCHDALE are also through after coming from behind to win 3-1 at home to Chesterfield.
Ian Henderson headed Dale level on 47 minutes, before Andy Cannon struck six minutes later and Nathaniel Mendez-Laing tapped in a late third.
BOLTON are out, though, after losing 4-2 after extra-time at Blackpool. Two late goals cancelled out Jamie Proctor’s opener for Wanderers, and although Kaiyne Woolery’s stoppage-time strike kept the tie alive, Jim McAlister and John Herron then struck for the Seasiders.
The draw for the second round will be made after the final first-round games are played on Wednesday night, when BURY visit Burton looking to follow up Saturday’s opening-day win over Charlton.
