MLB | Super Nasty Curve 

That is some wicked spin they are putting on those balls

Greinke has such a cool delivery

Matt Brash has some brutal pitches

M.y favorites are when the batter ducks and then sees where it stops!!

0:13 that curveball slowed

The movement on those pitches how could you hit them lol

Berrios as a jays fan is more of a slurve more than a curveball or in modern baseball known as a sweeper it's got more slider movement than curveball movement but all are very very nasty curveballs

Can somebody explain to me how THE FUCK the catchers are able to not only catch these balls but catch them in the middle of the batter swinging at it.

Spelled savage wrong, embarrassing

Barry Zito still has the nastiest curveball
