The Top-Five Pirates Prospects by Projected WAR
Yesterday, Kiley McDaniel published his consummately researched and demonstrably authoritative prospect list for the Pittsburgh Pirates. What follows is a different exercise than that, one much smaller in scope and designed to identify not Pittsburgh’s top overall prospects but rather the rookie-eligible players in the Pirates system who are most ready to produce wins at the major-league level in 2015 (regardless of whether they’re likely to receive the opportunity to do so). No attempt has been made, in other words, to account for future value.
Below are the top-five prospects in the Pittsburgh system by projected WAR. To assemble this brief list, what I’ve done is to locate the Steamer 600 projections for all the prospects to whom McDaniel assessed a Future Value grade of 40 or greater. Hitters’ numbers are normalized to 550 plate appearances; starting pitchers’, to 150 innings — i.e. the playing-time thresholds at which a league-average player would produce a 2.0 WAR. Catcher projections are prorated to 415 plate appearances to account for their reduced playing time.
Note that, in many cases, defensive value has been calculated entirely by positional adjustment based on the relevant player’s minor-league defensive starts — which is to say, there has been no attempt to account for the runs a player is likely to save in the field. As a result, players with an impressive offensive profile relative to their position are sometimes perhaps overvalued — that is, in such cases where their actual defensive skills are sub-par.

As McDaniel notes, Diaz was signed as an 18-year-old out of Venezuela for just $20 thousand. Age and bonus amount are pretty strong indicators of a Latin American player’s prospect status — and Diaz’s indicators suggest that his status as a prospect wasn’t “very highly sought after.” Statistically, though — with the exception of a couple low-BABIP seasons — he’s demonstrated a promising and constantly improving offensive profile, never striking out in more than 20% of his plate appearances and always exhibiting something better than negligible power. Moreover, his defensive skills at catcher appear to be his actual strength. Considered altogether, that’s a promising collection of qualities — one that renders him probably somewhere above replacement level.
