Some colorful baseball terms we rarely hear anymore. Most of these died long ago. These are just a few off the top of my head, but there are many I've missed. I enjoy the old-style phrases and terminology.
Can of corn
Stepping in the bucket
Pickle (usually referred to as a rundown nowadays)
Runner dying on base
Dead fish (Pitch thrown with very little speed)
Hat trick (Now mostly associated with ice hockey. This is now called a cycle)
