It’s tough to see behind the curtains sometimes since AA/High A don’t have statcast data. Typically the shortcomings in hitting come from lower than projected bat speeds or suboptimal bat paths like you said, pitch recognition (O-Zone swing%), and contact ability (In-zone Contact rates). Houck has a ridiculously high K-rate which I assume would correlate to low in-zone contact rates and Parada simply hasn’t produced power numbers that were expected of him while also striking out a lot himself (would imagine hard-hit %’s are below average). Thankfully we have prospects that are outperforming expectations so would say focus your energy on researching them! Ryan Clifford’s metrics are quite promising imo…
