there is a big difference in being a "pro" baseball player, and being a "Major Leaguer". You could spend your career in Single A baseball and be a "pro" player.
Difficult, but not impossible. Work hard, and you can get there.

Originally drafted by the Mariners and was known then as David Arias.
Traded to the Twins for Dave Hollins in 1996. He played with the Twins until 2002, when they non-tendered him after the 2002 season - fearing he would get a big raise in arbitration.
He then signed with the Red Sox and has been the heart and soul of their line-up since.

I haven't played baseball since 5th grade and I am currently in 10th grade and I wanted to try out for baseball in spring. Can somebody give me any suggestions on how I could get better (again) by then.

Do you have to start at lower ranks and work your way up? Do you have to take a special training class?

I wanted to get details on how to become a baseball score keeper?

How can you even get started at a lower level. My teenage son is interested in this and I want to provide him with this opportunity.

I am currently not that good!!!

All major league franchises have open try outs with there minor leagues teams. Your best bet is to contact the local minor league franchise owned by the major league team and see what their schedule looks like.
