Scouting reports

  • Kade Anderson Stat Grounded A 1.1 ERA and a 0.6 WHIP at Double-A aren't numbers that need context — they're the argument. Anderson has struck out 135 batters against 13 walks across 93.3 innings at AA this season, and the command profile translates cleanl...
  • Ryan Sloan Stat Grounded The walk rate is the whole argument: 16 free passes across 101.3 innings at AA, translating to a 2.1 BB/9 when the MLB average sits at 3.2. That kind of command at 20 years old in Double-A is genuinely rare, and the 27% K-BB% a...
  • Lazaro Montes Stat Grounded Thirty-eight home runs across AAA & AA at age 21, with a .309 ISO that translates to .215 at the MLB level — the power here is loud enough to survive the conversion. The problem is the strikeout rate, which goes from 31% in the...
  • Felnin Celesten Stat Grounded The .273/.363/.458 line across AA & A+ is genuinely tidy for a 20-year-old shortstop, but the translation softens it fast. That .185 ISO in the minors becomes a .135 MLB equivalent, which is below league average, and the 24% st...
  • Michael Arroyo Stat Grounded The contact is the carry here. Across AAA & AA in 2026, Arroyo is hitting .283 with just 87 strikeouts in 532 plate appearances, and that 16% clip translates to a 19.3% K-rate while the typical MLB hitter strikes out 22.0% of t...

Stat Grounded

SS / AA / WSN

The walk rate is the loudest thing in the profile. Eli Willits has drawn 95 walks across AA & A+ & A this season at 18 years old, an 18% clip that translates to 12.7% at the MLB level, and the .406 OBP it produces in the minors...

Stat Grounded

P / AA / SEA

A 1.1 ERA and a 0.6 WHIP at Double-A aren't numbers that need context — they're the argument. Anderson has struck out 135 batters against 13 walks across 93.3 innings at AA this season, and the command profile translates cleanl...

Stat Grounded

CF / AAA / MIN

The contact rate is the headline: 15% strikeouts across AAA & A+ & A translates to 18.7% at the MLB level, well below where most big-league hitters land, and that's with a .237 ISO in tow. At 21, Walker Jenkins is posting a .41...

Stat Grounded

P / AA / LAA

The K-BB% across AA & A+ sits at 24%, and the translation puts that at 14.9% in an MLB context, a tick above league average, which is roughly what you'd expect from a back-end starter who misses bats without embarrassing himsel...

Stat Grounded

P / AAA / CHW

The strikeout rate is the whole argument: 13.4 K/9 at AAA, translating to 10.3 against MLB hitters, well clear of the 8.6 MLB-average mark. The problem sits right next to it — 40 walks in 58.3 innings, a 6.2 BB/9 that translate...

Stat Grounded

P / AA / STL

The strikeout stuff is loud, 130 punchouts across 103 innings at AA, an 11.4 K/9 that translates to 9.1 at the MLB level, but the walk rate is the whole argument. At 4.7 BB/9, the 54 free passes he's issued translate to 4.6 at...
