The problem with that is that 1) Salazar uses that pitch a ton(13th of 78 qualifiers in 4 seam uses) 2) his second pitch is a changeup which also loses effectiveness as the fastball loses velocity and 3) his other pitches are used so little we can't be super confident they'd be effective alternatives. If Salazar had more MLB innings that highlighted the strength of those 3rd-5th pitches or we could be more certain he'll keep his stuff through 200+ IP that'd help, but we don't have either of those yet. For another small datapoint, September was his worst month performance wise, and he also failed to average 95 mph in 5 of his final 6 starts(he averaged 95+ in 14 of the other 24). This has been a lot of words on what was really a minor point in the overall comparison though, I want to make sure to describe it thoroughly because it's a bit in the weeds and interesting to me conceptually, but Salazar's specific repertoire isn't the linchpin of why I prefer Teheran over him. I'm grabbing this post because it's the last one in the sequence, but isn't it likely that a guy losing velocity on the 4 seamer is going to lose similar velocity on the change up? I mean, not exactly on a 1:1 scale, but reasonably close enough that you're still going to have a decent delta in there to continue having the deception you're looking for?
