Many players have played for numerous teams but what is so unusual about San Francsico Giants outfielder Ellis Burks. As faar as I know he's the first to accomplish it.

This probably isn't the answer.
I'm not sure if he's the first to do it or not.

Ellis Burks has worked his way from East to West throughout his career.
Started with Boston, went to Chicago, on to Colorado and finally to San Francisco.

May also have something to do with playing in all 4 time zones.

Leprechaun, you should have more faith in yourself. Youe answer is exactly what I was looking for. Congratulations
