Something has changed for Jordan Walker, now 24, 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: OPS moved from 0.581 to 0.887, which now sits in the 82th percentile leaguewide. It hasn't been all one direction. Chase% has slipped from 33.7% to 35.0%, but the trade has largely worked so far.

Walker has gained ground on Launch Angle (9.7°→14.4°), Bat Speed (76.1 mph→77.1 mph), and Ground-Ball% (48.6%→39.8%), while slipping on Swing Length (8.2 ft→8.3 ft) and Oppo% (24.9%→24.1%).
