The majority of the top pitchers in baseball have dominant fastballs.
Soon-to-be American League Cy Young winner Justin Verlander flashes a wicked 95-97 mph fastball, while two-time N.L. winner Tim Lincecum lives in the 92-97 mph range. C.C. Sabathia, owner of 176 career victories, owns a mid-90s fastball, as does arguably the most dominant pitcher in baseball, Roy Halladay, who at age 34 can still hurl with the best of them.
As such, it only makes sense for scouts to put velocity at the top of their list while scouting high-school and college talent. After all, velocity is the one thing you can't teach.
Following that same logic, most of the top pitching prospects in each team's organization just so happen to be some of the hardest throwing players.
So without further ado, I present to you the hardest throwing prospects in baseball, one from each team, and in most cases you'll see that that player just so happens to be the team's top overall prospect, save for the few teams who's top flamethrower just so happens to be a reliever.
