Answer
Carlos,
Who told you you need to throw 90 mph from 3rd base?  This is not accurate.  A 3rd baseman with a good arm is certainly a plus, but there is no 90mph requirement as far as I know.  The best way to increase arm strength is by playing long toss and strengthening your rotator cuff muscles.

This is a link to a response to a similiar question where I detail a good long toss regiment.  Check it out and then let me know if you have any further questions.  Hope this helps, Carlos.  Good luck.
