🐾 Jade-ringed cells = top 4 HR-vulnerability flags (above-league BRL%-A, HH%-A, Pull%, xwOBA on this pitch). The pitches getting hammered. ⚡ PUT-AWAY = his go-to out-pitch (highest 2-strike K rate · 30.0% put-away); a 🐾 EXPLOIT tag means even that pitch is getting hit hard. Platoon detail below breaks each pitch into vs-LHB / vs-RHB — the jade-tagged side is the one hitting it hardest (the exploit), and the ⚡ PUT-AWAY tag marks his top out-pitch separately vs each hand.
