My point is simply that the Phillies haven't done a good job developing players up to this point, and if they can revamp the coaching in the minor leagues, and take some of their young pitchers up a notch or two, they can produce some solid SPs.
As far as Sixto's velocity, call me when he throws a 100 pitches and tell me his velocity on the 100th pitch.
Again, another "uncertainty" that was never resolved because he couldn't stay healthy.
I'm not knocking his upside, just pointing out that he isn't close to a sure thing.
You won't know if he is for real until he starts 26 games, pitches 130+ innings and can sustain his velocity and command (first to go with arm fatigue) and not break down.
The thing that impressed me about Pivetta last year is he didn't lose velocity over 100+ pitches, that's "true" velocity for a SP (RP is another story, you're rarely throwing more than 20 pitches, but "bounceback" is key, can you bring it the next day? That's the issue with SD). His problem is lack of movement on his FB, whereas Eflin has developed a 2 seamer that showed good movement last night.
Sustained velocity is what matters,
Halladay for example, during his peak years averaged 93-94, t96-98.
Scherzer 94-95, t98-100.
