At League One AFC Wimbledon as they dug out from a deficit to achieve the Carabao Cup third round and secure Manuel Pellegrini's first win as chief.

Joe Pigott headed the hosts ahead from Mitchell Pinnock's corner.

Wimbledon's Rod McDonald was sent off following 18 minutes however West Ham needed to hold up until the second half to balance. Issa Diop made it 1-1 preceding Angelo Ogbonna scored the guests' second, with Javier Hernandez fixing the win.

Wimbledon delivered a gutsy guarded execution to disappoint the Premier League guests, who rolled out nine improvements to the side that began a weekend ago's 3-1 vanquish at Arsenal. Ukraine forward Andriy Yarmolenko, marked by Borussia Dortmund, and Spanish forward Lucas Perez, acquired from Arsenal, made their first begins.

However, the Hammers, base of the Premier League table after three straight thrashings, were behind after only 72 seconds as Pigott, who played in non-alliance for Maidstone last season, found the net with an eminent header. McDonald was expelled after two appointments in the space of five minutes for fouls on Robert Snodgrass and Hernandez.

West Ham was not ready to exploit the additional man advantage until halfway during that time half when Diop terminated home from outside the punishment region, the French protector's first objective since joining the club from Toulouse for a club record £22m in June. The Hammers led the pack out of the blue with seven minutes remaining: Ogbonna with a header from Snodgrass' corner.

Hernandez scored the third in included time in the wake of taking the ball round manager Tom King.'I was stressed' West Ham supervisor Manuel Pellegrini: "I was concerned in light of the fact that you play against these groups that protect extremely well and after that, you are losing 1-0 in the principal minutes, subsequent to working the entire week not to endure those sorts of objectives.

"The best thing the group did today around evening time was that we resisted the urge to panic - we kept moving and making space. "It's critical to win. In the event that we lose this diversion, that is another outcome - it's imperative. We have to keep working and I trust on Saturday we can have our first triumph in the Premier League." AFC Wimbledon supervisor Neal Ardley on the red card: "At the time I was shocked. The principal yellow is sufficiently reasonable as he misses the ball. The second, I think he has gone down simple. In our group that happens everywhere throughout the pitch and it's not given.

"It's a huge choice. We can't cause them issues after that and it would have been the assault against Safeguard. It's a distinct advantage."
