An essential aspect of any projection system that’s worth a damn is the integration of minor-league data into same — and the translation of that minor-league data to its major-league equivalent (MLE). The Steamer projection system, being worth several of damns, produces MLEs for what appears to be almost every minor-leaguer who exists — and probably some who even don’t.
Yesterday, I asked Steamer owner and operator Jared Cross for the MLE hitting data that’s currently being utilized for the production of Steamer’s rest-of-season and updated forecasts. What follows are four leaderboards featuring that data — specifically, of the MLE batting leaders by various, hopefully useful, criteria.
The first two leaderboards feature minor-league batting leaders (first all of them, and then just prospect-aged one) by translated wOBA. The second pair of leaderboards feature minor-league leaders by translated FIB* — a wOBA estimator (discussed here) which accounts only for home runs, walks, and strikeouts and which has some value insofar as those metrics become stable at least 1,000 plate appearances before BABIP (which metric influences wOBA considerably).
Below the aforementioned leaderboards, followed by some brief comments of varying quality.

Brief Comments of Varying Quality:
- With regard to overall MLE wOBA leader Kyle Roller, here’s who Kyle Roller is: an eighth-round selection by the Yankees in 2010 out of East Carolina University. And here’s who else: a prospect who’s always (a) been old for his levels and (b) produced above-average offensive lines relative to his leagues.
- Despite leading all prospect-age hitters by translated wOBA, Seattle infield prospect Gabriel Noriega’s line at Triple-A Tacoma is also mostly informed by batted-ball outcomes. Indeed, he hasn’t recorded an above-average offensive line since 2008, in the Rookie-level Appalachian League.
- That said, other Seattle infield prospect Chris Taylor — 16th among all minor-league hitters by translated wOBA and just fifth among prospect-age minor-league hitters — received the 38th-best WAR projection among rookie-eligible players before the season.
- Among the top prospect-age hitters by translated FIB* is Jose Ramirez, which Cleveland infield prospect (a) was recently promoted to the majors and (b) JD Sussman considered briefly in Monday’s edition of the Prospect Watch.
- Do you even Mookie Betts?
