I don't which stations might be associated with cricket grounds, but a giant pair of wicket keeper's gloves.
Or goalkeeper's gloves, if Ashton Gate ever reopens (though it wouldn't have a terminal platform).
Oval on the Northern line or Arsenal on the Piccadilly line though neither are terminating stations

And anyway Arsenal have since moved on.
Although Drayton Park is maybe a little closer, Arsenal is still the closest main 'tube' station to the Emirates (along with Holloway Road - closed on match days).
