Something has changed for Miguel Vargas, now 27, between 2025 and 2026. We went through what the data can actually measure, including contact, plate approach, swing shape, and the results they produce, to separate the signal from the noise. The clearest gain: BB% moved from 10.0% to 15.3%, which now sits in the 94th percentile leaguewide. It hasn't been all one direction.
