What Others Said:
Solid bat-missing ability and a knack for inducing weak, ground-ball contact points to more of a floor than ceiling for Peterson, but it might not take him that long to reach that potential. –

Peterson doesn’t have elite stuff, but it should be good enough to get big league batters out.  – Prospect 361

It’s pretty obvious that Peterson isn’t going to emerge as an ace, but he should be able to develop into a solid starter for the Mets.  He brings a strong repertoire, as described by

  • Fastball – “fastball is average in terms of velocity, as he’ll sit at 89-91 mph and touch 93, but few starters in the Minors can sink and command it as well as he does…”  Baseball America adds that, “the extension in is delivery that makes his 87-92 mph fastball look faster”
  • Slider – “plus slider that has good depth and bite, registering in the 82-84 mph range…”
  • Changeup – “fringy changeup registers in the same velocity band and would benefit from more separation…“

It will be interesting to see how the stuff plays at the highest level, especially since he has never set foot on a Triple-A diamond.  He did show a strong skillset at Double-A in ’19, displaying strikeouts (13.7% SwStr%), control and an ability to generate groundballs (52.6%).  He owns a minor league career 2.10 GO/AO as well as 243 K vs. 68 BB over 247.2 IP.  Maybe he’s not an ace, but at the very least he’s a streaming option depending on the locale/matchup.
