Everyone loves a big fastball.
As much as we claim to have fun watching soft-tossers like Tim Wakefield, Jaime Moyer, and Livan Hernandez pitch, the type of pitching that sells tickets comes with the arms of baseball's flamethrowers.
These are the guys whose fastballs you can hear. With them, the approach at the plate is to swing early and hope you make contact.
Not everyone on this list is an elite pitcher. In fact, some of these pitchers are not very highly-regarded at all.
But it is nevertheless a spectacle watching these men pitch.
That being said, here are the 10 hardest throwers in baseball.
Note: Pitch speed data is taken from Fangraphs, using highest average fastball velocity between 2009 and 2011 among pitchers with at least 50 IP.
