OK Bob I'll try. He's not the chattiest of children but here's what I've got so far:
1. Each level you go up, the pitchers miss less and less so you have to be ready when you get that "mistake" or you have to learn to take the pitches you get where they are pitched. In other words, no more pulling every fast ball for HRs (he's a lefty and his HRs were LCF or LF).
2. There is no room for extras in your swing (quiet your hands, shorten your swing, get your base strong [and use it], get rid of the waggles, twitches, bells and whistles)
3. Pay attention in Spanish class. Just like the pitching, it's a lot faster in the pros LOL (plus if you look like you could be from the DR they WILL come up and speak to you in Spanish...poor guy he's SOL on this one).
4. Sometimes you're just going to get beat. Don't be a baby about it. It's a very long season.
5. Be coachable but know enough about your swing and your game to understand the coaching and ask questions if needed so that you are not just making blind adjustments that don't make sense to you.
