FWIW, Z-Contact numbers for various recent Cubs at AAA and MLB
PCA ('23/'24) - 79.8% / 77.2%
Caissie - 82.7% / 79.3%
Mo Baller - 86.4% / 83.7%
Matt Shaw - 85.9% / 86.4%
Worth noting that PCA since the start of last year is at 84%, and Mo/Caissie's numbers are better this year than they were in their cups of coffee last year. So like, a 3 point drop is basically the high end of what you could expect, and generally it's less than that as guys get their feet under them.
Pedro Ramirez at 95.2% is elite. Would rank 4th in MLB last season behind Nico. Even if you lop 3 full points off hes still ~90th percentile, in line with guys like Jung Hoo Lee and Jose Ramirez.
Pedro is an absolute data darling.
