what does it take to throw a 90mph fastball?

Answer 1

grip it so the seams cross your fingers, a 4 seam fast ball. work your arm, espescially your rotator cuff. make sure that it is strong, however, the most important thing in pitching speed, is your legs. look at clemens or randy johnson's leg strength. its all about getting the transfer of weight between the two legs. however, as a college baseball player myself, and a little league coach (my brother and i taught my little brother how to pitch and at 12, he already throws in the high 60s), there are two things to remember, first of all, dont wear your arm out, i tell this espescailly to my little leaguers, because if they want to make it to the big leagues, their arm has to last them up to 35 years. also, there is no point in throwing fast if you cant throw accurate. id much rather take a kid in the draft who throws 50 mph and over the plate 90% of the time, than a kid who throws close to 70 mph and cant find the plate.

Answer 2

You need a strong arm, VERY strong legs, and the ability to work the two of them together as a team. I don't know how old you are, but it's important not to try to throw too much junk when you're young. You're only going to damage your arm at a time when it's still developing, and at all but the best high school levels, the ability to change speeds and place your pitches is going to get you looked at by colleges. If you have a good coach, father, etc... listen to them. ALWAYS warm up your arm before you put heat on the ball. You screw that arm up now, you'll never get there. If you throw enough to get sore, (even a little), ice it down when you're done. If you want to play ball after highschool, you're way better off being a pitcher that throws smoke, and can hit his spots, but has no junk, than you are a junk-baller with a sore elbow, and a torn up shoulder.

Answer 3

Honestly, I think just as is portrayed in the movie Bull Durham, having the Gods bless your arm is probably the most important thing. If you're in HS, and can throw hard enough to approach 90, you might be able to pull it off some day if you get drafted and work with MLB pitching coaches. If you're in the low 70s, I honestly think you'll hurt your arm before ever being able to hit 90 MPH. I wouldn't push yourself unless you've got some coaches that really know what they're doing. Its sad how many true talents blow their arms before they even get signed because they aren't well coached.

Good luck, and be careful!
