Something has changed for Yordan Alvarez, now 29, 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: xSLG moved from 0.686 to 0.965, which now sits in the 98th percentile leaguewide. It hasn't been all one direction. Oppo% has slipped from 29.8% to 20.5%, but the trade has largely worked so far.

The Results

On the bottom-line production (what it all adds up to), the arrows point the right way. Alvarez has improved on xSLG (0.686→0.965), OPS (0.769→1.004), and xwOBA (0.393→0.493), with nothing here moving meaningfully against him.

Section 3 / 4

Plate Approach

On his approach at the plate (what he swings at and how often he misses), it's a genuine mix. Alvarez has gained ground on Whiff% (22.4%→18.4%) and BB% (13.7%→14.2%), while slipping on K% (17.5%→19.3%) and Chase% (26.2%→26.2%). The net picture is a real shift in profile, not a simple up-or-down.

Section 4 / 4

Swing & Batted-Ball Shape

On his swing and batted-ball shape (the mechanical fingerprint behind the changes above), it's a genuine mix. Alvarez has gained ground on Launch Angle (18.0°→18.7°), Bat Speed (74.8 mph→74.9 mph), and Ground-Ball% (35.5%→29.5%), while slipping on Oppo% (29.8%→20.5%). The net picture is a real shift in profile, not a simple up-or-down.

Verdict

The takeaway

Bottom line: between 2025 and 2026, the broad picture is a step forward, and the results are following the process. More of Alvarez's underlying markers are pointing up than down. It's worth re-checking as the sample grows, but the direction is already readable in the numbers.
