Beware of hypertrophy for hypertrophy's sake. Adding muscle gained via sarcoplasmic hypertrophy/increased energy storage will be of little benefit and may in fact reduce your performance (train slow, be slow).
You will probably benefit from the power variations of the oly lifts, jerks, and the foundational strength exercises (squats, presses, rows, etc.).
The thing you need to realize is that most of the skills in baseball lay toward the speed end of the force continuum. Baseballs and bats do not weigh too much so too great an emphasis on increasing maximal strength will eventually slow you down.
Your program should always include (in approximate order of importance):
1. Baseball skill training
2. Speed activities
3. Speed-strength training (includes rotational activities)
4. Foundational Strength training
5. GPP as needed (additional energy system training, flexiblity, restoration, etc.)
6. Practice your autograph for when you make it big
The amount of each will depend on time of year relative to the season, your training tolerance, and your immediate/ongoing needs.
