A new ball will come out faster then a ball that is used....and as for goico serving the ball 145 mph i dont belive it. The ball will come out faster with a reverse then a right side .....remember milford was having contest to see who throw the fastest. i think wayne got to 128 or something. the hardest rightside i have i have heard of is elorduy, the hardest reverse o have seen is davie then lopez. davie plaued in conn and ft pierce and ocala.
