The well named Hunter Greene, a pitching prospect in the Reds system, is lighting up the radar gun:

In that start (see the highlights above), Hunter Greene was clocked as throwing 37 fastballs at 100 MPH or higher. According to JJ Cooper of Baseball America that is the most 100+ MPH pitches we’ve ever been able to track in a single game during the pitch tracking era, which dates back to 2007. In the big leagues only Jacob deGrom has thrown 30 100 MPH pitches in a game. He did so on June 5th this season. It’s the only time it’s ever happened in Major League Baseball. Greene has done it three different times this season in the minors.

Greene is averaging 12.6 K per nine this season, split between AA and AAA. He is seasonal age 21, and while he had nothing to prove at AA, AAA is a little tougher for him. He’s still pitching well there, but not so well that he’s obviously ready to help the Reds this year. I suspect we’ll see Greene on the Reds sometime next year.
