Who are the hardest-throwing pitchers in baseball?

Yordano Ventura Royals

Reds flame-thrower Aroldis Chapman is almost ready to return from facial fractures, but in the meantime the Hardest-Thrower In Baseball title belongs to someone new.

Here are the leaders in average fastball velocity after one month of the season among pitchers with at least 10 innings, according to Fan Graphs:

STARTERS MPH
Yordano Ventura 96.7
Nathan Eovaldi 96.0
Garrett Richards 95.9
Gerrit Cole 95.6
Jose Fernandez 95.4

Ages of the five starters with the fastest average fastballs: 22, 24, 25, 23, 21. And apparently being named Garrett/Gerrit helps, too. My crush on Yordano Ventura is well-documented in this space, but suffice it to say that the Royals rookie is living up to the hype, velocity-wise and performance-wise, leading all starters with both a 96.7 mph fastball average and a 1.50 ERA. He’s a bad, bad man.

RELIEVERS MPH
Kelvin Herrera 97.1
Carlos Martinez 97.0
Jordan Walden 96.7
Jake McGee 96.7
Trevor Rosenthal 96.2

Just for some context, Chapman averaged 98.3 mph with his fastball last season. St. Louis places setup man Carlos Martinez and closer Trevor Rosenthal in the top five velocity list and Jake McGee of the Rays is the only left-hander in either top five.

Oh, and the softest-thrower in baseball? Knuckleballer R.A. Dickey at 82.0 mph, followed by slop-slinging southpaws Mark Buehrle at 83.2 mph and Bruce Chen at 83.9 mph.
