Okay. From a baseball standpoint you're going to want to figure out if it was in fact a fractured growth plate or a torn labrum; the labrum can imply some debilitating athletic ramifications as a ball player. Gosh, I hope for your sake it's not in your throwing arm... Also, are you sure the injury was from lifting and not from actually playing the game of baseball? Baseball can do some nasty things to the body, and if you're following a sound strength training program it shouldn't be injuring you, but the game itself still might. As baseball players we need to lift not only to play the game in a more physical manner, but also to stay injury free.
As far as lifting tricks or tips go, make sure to hit the legs hard (as should all athletes) and really focus in on your rowing and chinning movements. These are money for you. And, once again, keep pushing the food. I know it's not the most fun thing to do, but the best advice I could give you is eat till you're full and then eat 1 more sandwhich, 1 more chicken breast, or drink 1 more tall glass of 2% milk. Alot of guys I played with over the years got really into the med ball movements, and I saw some success with those myself, but only after a decent level of strength was built up.
To specifically state why I told you to avoid the ezinearticles program is due to a lack of periodization, lack of fluctuating volume/intensity, lack of progression, and some pretty contested exercies (leg curls, pushbacks, leg press, leg extension, pushdowns, even pull-downs). Stick with chins, rows, dumbbell pushing exercises, squats, deads, single leg movements, and hit the posterior chain hard. Cycle em in, push it in the offseason with intensity and volume, and scale back on the volume when the season starts. Work the midsection, but don't limit yourself to high rep work only. Hit these hard and heavy, and you should be okay. The article doesn't list any reps under the number of 8, which in my mind is an athletic hazard. You gotta go heavier if you want to hit the long ball. Nutritionally the article wants you to take protein powder, creatien, glucosamine, chondroiton, glutamine, ZMA, and a multi. Just focus on eating food man. You can't go wrong with good ol' healthy calories.
I hope all this helps. Also, make your way over to elitefts and search their articles for baseball stuff. Cressey has some great ideas on that website for pressing movements too.
