Updated Top 10 Prospects (2020): Arizona Diamondbacks: Flush With Bats, Intriguing Arms Join Future


There was no question that the Diamondbacks were flush with intriguing young hitters, led by a trio of outfielders and a catcher (though he could transition to the outfield himself). The pitching prospects weren’t necessarily there, so it’s no surprise that they addressed that in the 2020 draft. Where do the new prospects fit in? Let’s take a look:

  1. Daulton Varsho (C, Grade – B+)
  2. Kristian Robinson (OF, Grade – B+)
  3. Alek Thomas (OF, Grade – B+)
  4. Corbin Carroll (OF, Grade – B+)
  5. Bryce Jarvis (RHP, Grade – B)
  6. Geraldo Perdomo (SS, Grade – B)
  7. Corbin Martin (RHP, Grade – B-)
  8. Luis Frias (RHP, Grade – C+)
  9. Levi Kelly (RHP, Grade – C+)
  10. Slade Cecconi (RHP, Grade – C+)

Why Jarvis at #5?

Based solely on his work during the abbreviated 2020 season Jarvis would seemingly grade out higher than a “B”.  However can we truly draw definitive conclusions based off of a handful of dominant innings?  After being selected in the 37th round in 2019 and not signing, there was obvious improvement as he added weight and developed his arsenal.  Here’s what MLB.com had to say:

After working with an 88-93 mph fastball at the beginning of 2019 and dipping to 86-91 by season’s end, Jarvis added 20 pounds to his 6-foot-2 frame and operated at 92-96 with effective downhill plane last fall and this spring. His breaking ball used to be average at best, and now he flashes a plus curveball in the upper 70s that he can manipulate into a distinct and equally effective slider in the mid-80s. His fading changeup remains his best secondary offering, grading as well above average at its best.

Baseball America noted that he struggled with his control over his first two seasons, something that will have to be monitored at the next level.  We also have to see if he can maintain his improved stuff over a full season, something we haven’t yet had the opportunity to see.  The answers to those two questions will ultimately determine his value, but he has the opportunity to be a top of the rotation arm before long.

Why Cecconi at #10?

You definitely could argue him over Luis Frias and Levi Kelly, but at the end of the day the makeup and questions are the same.  Some feel Cecconi ultimately profiles better coming out of the bullpen, especially after MLB.com noted that “his velocity drops off as he goes deeper into starts”. 

That’s not the only question hanging over him, though you have to wonder if this trio could form a dominant bullpen a year or two down the line (assuming Cecconi ultimately signs, which isn’t a given).
