Danny O'Brien brace and Sam Cosgrove winner give Latics the edge over Port Vale at Christopher Park.
- Sam Cosgrove scores second-half winner for Peter Atherton's side.
- Danny O'Brien had given Latics a 2-0 half-time lead.
- Port Vale's Dan Turner grabbed a brace to draw the scores level on the hour.
Wigan Athletic's development squad recorded their second win from three games in the Central League Cup group stage as Sam Cosgrove stuck a 68th minute winner for Peter Atherton's side after they had thrown away the two-goal advantage that Danny O'Brien's first-half double had given them.
Vale, who included former Latic Michael Brown in their ranks, replied twice in the second-half through Dan Turner but Cosgrove made sure his side collected the three points, scoring the fifth goal of the game for 3-2.
Latics were ahead inside 90 seconds as O'Brien was played in down the left channel before finishing coolly past Miguel Santos at close range.
Both sides made a couple of half-chances before Atherton's side took full control on 16 minutes as a wonderfully worked move starring Luke Burke - fresh off signing his new contract -, Cosgrove and James Barrigan linked up before the latter crossed for O'Brien to head home at the far post.
A good recovery challenge from Burke and a good Dan Lavercombe save from Vale's Quentin Pereira kept the two-goal advantage intact at half-time, though the Valiants had a chance to level early in the second-half from the penalty spot only for Lavercombe to again produce a good save.
Vale found a way back into the game on 55 minutes as the lively Turner found himself in behind the Latics defence before finishing neatly past Lavercombe.
Turner's second came on the hour as he again beat the offside trap before producing another replica finish past Lavercombe.
The visitors were level for just eight minutes, though, as Cosgrove finished O'Brien's square ball emphatically after superb defensive work initially by Adam Anson.
With just one side going through from the group, though, Latics will hope Fleetwood Town - currently with two wins from two - lose to Morecambe when they meet in the final group match otherwise Atherton's side will exit the competition.
Latics: Lavercombe, Burke, Taylor, Gregory (Trialist 60), Stubbs, Anson, Barrigan (Lang 70), Baxendale, Cosgrove, Boyd (Randall 88), O'Brien (Powell 83).
