whats all the forearms drills you guys do and have heard of? any is appreciated thanks.

As far as forearms are concerned there is the following drills that most people do.

1.) Wrist curls
2.) The ever fun Rice Bucket for those pitchers

The other dril I know which is going to be strange to many of you Yankees down there is take a Hockey stick, (ya know the long piece of wood with a curved end that those crazy Canadians use on that indoor frozen pond called a hockey arena to chase around a little black puck) and take some rope and attach weights to either end of the stick and curl the rope up and then uncurl it around the stick a few times and then when you can do 3 sets of 12 increase the weight thats on the end of the stick, keep the stick arms length away from you and raised at shoulder height.

Hope this helps

Basically all there is for weights is wrist rolls and curls using various standing/sitting motion. For example with wrist rolls you can stand, holding a bar with a free weight attached on a rope to the bar, and roll your wrists up and down. Or you can kneel/sit down in front of a bench or table, with your arms straight laying on the bench or table, and hold a barbell over the edge of the table and do rolls that way.
Other things are the rice bucket, and Ted Williams says he used to do finger-tip pushups and squeeze rubber balls to develop his wrist and forearms.

Here are some exercises that are interchangeable. Use according to your coach's training program if he has an offseason program in place. If your school does not have enough players for a team program you might add some of these into your arm workout if you have not already done so.
1. Reverse Barbell Curls-primary muscles are forearm and bicep.
2. Hammer Curls-primaries again are forearm and biceps
3.Reverse wrist curls-primary is forearm
4. Behind the back wrist curls-primary are forearm
These are just variations of what has already been suggested.

Coach O,
what are hammer curls?

I believe hammer curls are arm curls while sitting down with the dumbells held down at your sides. You start and finish the curl with the palms facing in toward each other. Arm curls primarily target the biceps, but by angling your foreaems so the palms face each other helps target the upper forearms, the muscles just below the biceps under the elbow.

Mr3000 your close. Hammer curls can be done standing or sitting. Grab the dumbbells in each hand with your palms turned toward the midline of the body(facing inward). Inhale and curl the dumbbells to your shoulders. You can either alternate or do them together. Exhale as you complete the movement(return to the side).
This is an excellent exercise for a muscle called the brachioradialis. This muscle attaches (originates at the humerus near the lateral condyle and its insertion point is at the radius on the lateral side near the the distal end (farthest point of the bone away from the body near the styloid process (towards the thumb side of the forearm.
The brachioradialis helps to flex, semi supinate and semi pronate the forearm. This muscle is extremely important at release point of the throw and in keeping your top hand in place at contact at the plate.
