getting a late break is so important, i dont know how big your break us but i have friends with big curves but it doesnt have a tight spin and is real easy to read and see and it gets hit. i think what makes mine good is well i have a huge break but it also breaks very late and thats why people will swing at it no where near the strikezonem, you can have a huge break but if its not late anygood hitter will just wait back and watch it in and take it or serve it up for a hit
the late break is the difference between the pros and everyone else i went to spring training last season and have video of Mark Buerhle and Demaso Marte doing a bullpen (i hate the sox but i couldnt pass up getting video that good of pro pitching) i was right behind there bull pen catcher on the other side of this cage about 3 feet behind the catcher a great video and well the curves i will not lie have a great break but ive seen many highschool kids that get as much or at least close to as much break as both, i have video of me and my curve i think has as much total break as both
the difference though is when it breaks, i thought i had a late break LOL well its rediculous it seems like the pitch is a fastball until about 2 feet from the plate and just drops like 3 feet its amazing. like my curve has a big drop like and a later break then most highschool pitchers but well if mine dropped as late as theres i dont think anybody in highschool baseball could hit it, really sort of hard to describe how late it breaks its amazing how could of hitters there are in the majors that they can still hit these pitchers consistenltly
another major difference is there curves are faster then mine and the spin is real hard to pick up, like when i catch my friends they give me the glove signals for pitches but its no biggie if they dont cause i can still react when i see the spin but with these guys if they said a fastball was coming and it was a curve the ball would probably miss my glove by 2 feet
what i would give to have the stuff of pro pitchers those people are just freaks
