The one we would most likely lose is Ron Washington, and yes it has already been reported that Washington, the current 3rd base coach for the Atlanta Braves, is possibly at the top of the list for AJ Preller who is trying to fill his coaching spot for the San Diego Padres.
In fact, it has been reported that Ron Washington has had a formal interview with the Padres. Reports state that the Padres are indeed very serious about offering the job to Washington.
We will probably have several days of reports circulating before anything is finalized though.
