Dickerson may be turning a corner at the plate. He put up OK numbers at Inland Empire (.276/.387/.425), but considering the lack of power there was too much swing-and-miss. Early in Everett, the whiff is down, the power is up, and the power results aren't just about numbers in a better environment to hit. He's made more contact overall on swings, generated more loft, and he's getting to his pull side more. If most of it is sustainable, it's a pretty significant step in his age-22 season.

The power jump is bigger than the slugging line suggests. At Inland Empire, Dickerson hit a home run every 38.8 plate appearances. At Everett, every 22.2 — six in 133 trips after nine in 349\. His isolated slugging went from .150 to .200, and he pulled 46.3% of his batted balls after 39.4%, which is the seven-point move you noticed.

Here is the check on the environment question, and it cuts both ways. His wRC+ was 111 at Inland Empire and 111 at Everett — identical. The raw slugging gain was largely absorbed once the league and park were accounted for. But producing the same adjusted number at the harder level is not nothing, and the home run rate is the piece that survives the adjustment.

Your "early in Everett" framing turns out to be precisely the right window. Across his first 15 games at the level he struck out 21.5% of the time, down from 24.9% at Single-A. Across his last 15 he struck out 30.9%. The power held through both halves — three home runs and a .200 ISO in each — but the contact did not. The improvement was real and then it wasn't, which is a more useful thing to know in April than either half alone.

The tool nobody is talking about is his running. Dickerson stole 35 bases in 41 attempts, an 85% rate, and 14 of those came in 30 games after the promotion.

He also kept getting on base all year — 95 of 107 games — including a 25-game on-base streak from May 20 through June 27 with a 12-game hitting streak inside it. And of the 61 games where the log records a position, 46 were in center field.
