Cameron Congreve and Panashe Makokowe were on target as Swansea City Under-18s came from behind to run out comfortable winners against Crewe Alexandra.
Makokowe's own-goal left the young Swans trailing at the midway point in the first half of the Professional Development League clash at Landore.
But Byron Anthony's side equalised when Michael Williams put through his own net, before a Congreve free-kick turned the contest on its head.
Makokowe was then on target at the right end shortly after the restart to secure maximum points for the hosts.
Anthony had made three changes from the midweek draw with Ipswich Town.
Alex Rutter replaced Tyler Evans in goal, while Rio Campbell was recalled and under-16s midfielder Josh Carey was given an opportunity to impress from the start.
Congreve skippered the Swans and had the first shot on goal within a minute, but his effort was straight down the throat of Crewe keeper Tom Booth.
At the other end, Cian Williams blocked Charlie Finney's shot, while Rutter got down well to deny Joel Tabiner.
But the Swansea goalkeeper was powerless in the 22nd minute as Ben Wood's corner was inadvertently diverted into his own net by Makokowe.
The hosts then lost Geoff Bony to injury before the half-hour mark, but they responded well to those setbacks with Campbell drawing a smart save out of Booth.
And they drew level from the resulting corner, which deflected in off Williams at the far post.
The turnaround was completed within two minutes, as Congreve left Booth clutching at thin air with a precise free-kick into the corner of the net.
Aaron Hillier went close to stretching the advantage before the break when he fired over from close range, while Rutter kept out Finney at the other end.
The hosts did establish a two-goal buffer within four minutes of the restart.
Shortly after Iwan Morgan's goal-bound shot deflected over, Congreve's resulting corner was bundled in by Makokowe at the far post.
Despite the breathing space, the young Swans continued to attack in search of more goals.
Campbell saw a fierce strike tipped onto the post, while Morgan's curling effort was marginally off-target.
At the other end, Crewe's attempts to find a route back into the contest were stifled by a combination of stubborn defending and solid goalkeeping from Rutter.
