Here is an inspirational video clip about a player who made the 2010 Victoria Seals spring training roster after attending one of the open pro baseball tryouts held by the Golden Baseball League that year:
His story is not that unusual, especially for guys who have been overlooked and/or developed physically later than some of their teammates who either got drafted or were signed to independent baseball teams without having to attend a tryout.
You also get to hear the sentiments from the team’s manager, former Major League player Bret Boone. You may be in a similar situation to the player who made the spring training roster, so take the lessons from this video (and other ones you find) seriously if you wish to make (and stay on) any pro baseball team.
