The Top Prospect-Age Hitters by FIB*
Introduction
Minor-league regular seasons everywhere have come to their respective conclusions. Last week, before the author had become a really big deal and moved to Europe, he published a leaderboard of the top-10 qualified minor-league pitchers by kwERA (i.e. an ERA estimator derived entirely from just strikeout and walk rates).
Today, despite the fact that he’s a really big deal now and lives in Europe, the author has condescended to publish a second leaderboard — in this case, of the top-10 qualified minor-league hitters by FIB*, or Fielding Independent Batting (Asterisk). What FIB* isn’t is the same metric introduced to readers by Bradley Woodrum about two years ago. That one, called Fielding Independent Batting, but without the very integral asterisk, accounts for xBABIP and is presented as an index stat, like wRC+. What FIB* is is a batting metric calculated almost precisely like FIP, except then placed on the same scale as wOBA*.
*The equation, in full: [(HR*12 + BB*3 – K*2) * .141] + .3267.
Leaderboard: The Top Prospect-Age Hitters by FIB*
FIB* is a wOBA estimator which accounts only for home runs, walks, and strikeouts and was popularized — to the degree that it’s popular, at all — by the author just, like, 30 seconds ago. Below are the top-10 qualified prospect-age minor-league hitters by FIB* this season. (Note: batters who made zero appearances above rookie-level ball have been excluded, as have all Mexican League hitters, because their numbers are super loco.)
Rank | Name | Team | Level | Age | PA | HR% | BB% | K% | FIB* |
---|---|---|---|---|---|---|---|---|---|
1 | Miguel Sano | Twins | A+, AA | 20 | 519 | 6.7% | 12.5% | 27.4% | .416 |
2 | George Springer | Astros | AA, AAA | 23 | 589 | 6.3% | 14.1% | 27.3% | .416 |
3 | Zachary Borenstein | Angels | A+ | 22 | 465 | 6.0% | 9.2% | 18.9% | .414 |
4 | Ryan Rua | Rangers | A, AA | 23 | 525 | 6.1% | 10.7% | 21.9% | .413 |
5 | Joey Gallo | Rangers | R, A | 18 | 467 | 8.6% | 10.7% | 36.8% | .413 |
6 | Max Muncy | Athletics | A+, AA | 22 | 625 | 4.0% | 14.1% | 16.3% | .408 |
7 | Jabari Blash | Mariners | A+, AA | 23 | 452 | 5.5% | 13.3% | 25.0% | .406 |
8 | Mookie Betts | Red Sox | A, A+ | 20 | 551 | 2.7% | 14.7% | 10.3% | .406 |
9 | Maikel Franco | Phillies | A+, AA | 20 | 581 | 5.3% | 5.2% | 12.0% | .405 |
10 | Marcus Semien | White Sox | AA, AAA | 22 | 625 | 3.0% | 15.7% | 14.4% | .404 |
Three Notes
• Were he a year or two younger, San Diego minor-league first-baseman/catcher Robert Kral, 24, would actually appear atop this entire list, after having produced a .426 FIB* on the strength of a Cal League season during which he hit 13 home runs and recorded walk and strikeout rates of 18.5% and 15.0%, respectively.
• It’s entirely possible that Angels outfield prospect Zachary Borenstein, playing in his age-22 season, deserves more attention for his offensive skills. There’s also a non-zero change that he, like other hitters (including Robert Kral, above), benefited from the offensive environment of the California League.
• To that point, it should be noted that the calculation of FIB* in this instance makes no allowances either for park or league.

Today’s Complete Schedule
Here’s the complete schedule for all of today’s games, with our very proprietary watchability (NERD) scores for each one. Pitching probables and game times aggregated from MLB.com and RotoWire.
Note that these NERD scores are calculated using the methodology introduced recently and designed to account for the influence of playoff odds on the watchability of games. ***Unlike in recent iterations of this table, the author has adjusted the day’s NERD Game Scores such that, combined, they average 5.0.*** This allows said table to resemble more closely the Game Scores that have appeared here over the preceding four months.
