Call-up watch

Scouting reports

  • Franklin Arias Stat Grounded Everyday contact regular, with a useful reserve floor; he barely strikes out. The open question is damage. He is 20 in Triple-A and Double-A over 351 PA, so confidence is high.
  • Kyson Witherspoon Stat Grounded The walk rate is the whole argument here. Witherspoon is running a 4.1 BB/9 at A+ that translates to 4.2 at the MLB level, while MLB starters average 3.2, and his 78 strikeouts across 75.3 innings haven't been enough to offset...
  • Anthony Eyanson Stat Grounded A 1.1 ERA and 0.9 WHIP across AA & A+, both sitting at the 99th percentile of the pitcher pool, are the kind of numbers that demand explanation before belief. The K-BB% of 26% across those same 63.6 innings translates to a 15.6...
  • Justin Gonzales Stat Grounded The walk rate is the thing to watch. At A+ in 354 plate appearances, Justin Gonzales is drawing 47 walks against 66 strikeouts, a 13% BB% that translates to 10.0% at the MLB level, where the average sits at 8.5%. The raw ISO of...
  • Gage Ziehl Stat Grounded The walk rate is the whole argument here. Seventeen walks in 75 AA innings, and that control sits at the 96th percentile of his pitcher pool. The AA strikeout rate of 10.6 per nine softens to 8.6 in translation, right where the...

Stat Grounded

P / AA / SEA

A 1.3 ERA and a 0.60 WHIP at Double-A, across 77.7 innings, is the kind of line that makes you look for the catch. Ten walks in 276 batters faced — that's the whole argument. The translation puts his K/9 at 10.0 and his BB/9 at...

Stat Grounded

SS / A+ / WSN

The line does not show a second offensive strength at the same level; he forces pitchers into the zone and takes the free pass. The walks create an everyday path, but the present outcome is a reserve. He is 18 in High-A and Sin...

Stat Grounded

CF / AAA / DET

The strikeout rate is the lead. At AAA in 2026, Clark is punching out at 16% across 418 plate appearances — a number that translates to 18.7% against big-league pitching, well below a league average that sits around 22%. That's...

Stat Grounded

P / A+ / LAA

The strikeout-to-walk gap is doing real work here: a 22% K-BB% at A+ ranks 92nd percentile in his pitcher pool, and the 12.1 K/9 across 43.3 innings translates to 8.7 per nine at the MLB equivalent, which lands almost exactly a...

Stat Grounded

CF / AAA / MIN

The contact-plus-patience combination here is the argument. Across AAA, A+, and A this year, Jenkins is hitting .294/.398/.482 with 32 walks against 33 strikeouts in 231 plate appearances, and when you translate that discipline...

Stat Grounded

P / AAA / CHW

The 13.5 K/9 at AAA is the loudest number in the profile, and it translates to 10.3 per nine against MLB hitters while the league sits at 8.6. The problem sitting right next to it is 39 walks across 56 innings, a 6.3 BB/9 that...
