Well, Im not going to get into listing all of the muscles, but, some good exercises are as follows…
One Arm Dumbbell Rows, Lat Pulldowns, Zottman Curls, Facepulls and the list goes on.
The thing is, these are usually considered “accessory” exercises. Or exercises to be done in addition to the main core lifts…for baseball…squat, deadlift, bench and pull ups.
You want to stay away from heavy over head pressing and lateral raises.
So strengthening the decelerators is important. Doing pull ups and scapular pushups are a great place to start. If you are doing exercises like the lat pulldown, face pulls or Zottman curls please take the time to make sure they are being done correctly. Much more important to activate the right muscles with the movement than get sloppy to move more weight. Also, in season, you want to make sure you are not lifting to the point of being very sore. In fact, with a proper balance in programming and design a lot of soreness can be avoided when lifting.
