Hello,

This appears to be Alternaria fruit rot. Unfortunately there is no reliable chemical control against this disease. Your best course of action will be to remove all infected fruit from the orchard to make sure that inoculum doesn't remain into next year. It can be exacerbated by physical damage to the fruit by things like birds or hail.
