š°ļø Ever wanted to see a hitterās bat path pitch-by-pitch? I just launched v1 of an interactive app that maps MLB swing paths (2023 ASB ā 2025 July) using Statcast + Savant data. Try it here: https://t.co/tHM0G1w6WG ā potential features & current critiques welcomed!

9/ Bottom Line. What do you think? Cut some FF volume, lean SV+CH vs LHB & SV+SI vs RHB, add a firm cutter, and tighten FF and SI profiles. Will Soroka outperform his $7.5M tag in 2026? #PitchDesign #BaseballAnalytics #MLB #DBacks #WinterMeetings #Cubs #FreeAgency #Baseball

8/ Playoff Weapon A velo tick would be nice, and definitely should wield some interest for Soroka this offseason, but the bigger unlock is adding a firm cutter and creating more consistent shapes. With these improvements, weāre looking at a stable mid-rotation piece in Arizona

7/ Pitch Design Targets Adding a new pitch to your arsenal is no small task in itself. However, it would also benefit Soroka to shrink his current FB profile clusters in the latter part of the offseason when that should be the focus. The goal should be to tighten the FF cluster

6/ 3-FB Model in Practice Secondly, from a strictly intuitive stance, adding multiple FBs allows for more tunneling combinations. We know this adds concrete value despite yet being fully quantified. (image: https://t.co/xT9LKrgybP)

5/ Why This Works A cutter plays optimally for Soroka in multiple ways. First, the addition of multiple FBs has been a successful trend recently for multiple starters: Seth Lugo, etc. This has been a way to find value for starting pitchers through the use of a wide range of

4/ Arsenal Addition Add a cutter. He moved away from SL in 2024. In the past his SL and SV were only 0.9 mph apart, which was less effective. A firm cutter that lives between FF and SV, with less iVB than FF, creates a true bridge pitch and a usable third option vs both RHB &

3/ Usage Tweaks + Optimization His weakest pitch is his 4-seam according to the model, while Sweeper and CH carry better returns vs LHB, and SV+SI play better vs RHB.

2/ Context + Arsenal Snapshot Soroka's velo and extension are not a strength of his. His FB averages 93.6 mph vs RHP avg of 95.0 mph, and his extension sits in the lower third of MLB. Naturally, this means shape and usage carry extra weight for him. He wields a FF, SV, CH, SI.

šØ External Focus for Athletes š§µ Many athletes focus internallyāon mechanics, arm angles, or the feeling of āperfectā mechanics. Real development happens when training shifts to external focusātargeting outcomes. Hereās why this approach dominates in player development. š

When we had an @ouraring trial with the #Reds, we had pitchers use earplugs to test sleep/readiness quality and they had a small but significant positive impact, as did eyemasks/curtain clips. Oura readiness scores were also positively correlated with Stuff+ improvements, so...
i slept with earplugs tonight i thought i wasn't sensitive to sounds but i slept suspiciously well.. gonna try some more and report back
