Surfdog, the reality for players in talent deep areas like California is that it is very easy not to get noticed.
Notice that I did not say that it is hard to stand out.
Ways to stand out:
Be a total professional. Stand up at the fence at every point in the game and be a participant even if you are not batting or fielding. Help your teammates.
Practice with game intensity, look like a professional when practicing. Use good mechanics and dont goof.
In the on-deck circle, take a professionals approach in regards to total focus on preparing for upcoming at bat. Watch the pitch, practice mechanics, set your approach, be serious.
I'm not saying dont have fun. I am saying be a professional.
I believe make-up is what separated the noticed from the un-noticed in a skilled player.
