If you are lucky enough to go to spring training and spend a little time around a team’s complex before the ML game, you’re bound to see a few former players in town as instructors. Most of the guys suited up for that team at some point in their playing career, but it’s not a requirement of the job.
As noted in this story about The Panda, almost all of the instructors are no longer playing. I always enjoyed seeing him play in person and sitting along the third base line.
I'd rather be sitting in a ballpark.
