The All England Club has received a boost to its plans to build 39 new tennis courts on Wimbledon Park.
Officers at the Greater London Authority (GLA) have recommended the Deputy Mayor should grant conditional planning permission at a public hearing next Friday.
Merton Council approved the plans, but the proposal was referred to the GLA after Wandsworth Council rejected the scheme last November.
Officers say the proposal complies with most relevant planning policies and there are "no material considerations that are considered to justify the refusal of consent".
They admit there will be a loss of open space, and harm to protected Metropolitan Open Land, but conclude the "balance is clearly in favour of" approving the scheme.
