Who are the hardest-throwing pitchers in baseball?

13 Comments

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.

Mets pitcher Zack Wheeler will be placed on the 10-day injured list due to fatigue in his right shoulder, Newsday’s Tim Healey reports. The roster move is retroactive to July 12. Steven Matz will open up a two-game series in Minnesota, starting in Wheeler’s place on Tuesday.

As Healey notes, the soonest Wheeler can return is July 23, which would give him at most two starts ahead of the July 31 trade deadline. Wheeler has frequently been brought up in trade conversations as he can become a free agent after the season and the 42-51 Mets have been freefalling.

Wheeler, 29, owns a 4.69 ERA with 130 strikeouts and 34 walks across 119 innings of work this season.
