Earlier today, Kiley McDaniel published his consummately researched and demonstrably authoritative prospect list for the Oakland Athletics. What follows is a different exercise than that, one much smaller in scope and designed to identify not Oakland’s top overall prospects but rather the rookie-eligible players in the A’s 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 Oakland 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.

The right-handed Alcantara produced a strikeout- and walk-rate differential just above 15% in 2013, placing him at approximately the 90th percentile among all minor-league pitchers by that measure who recorded at least 100 innings or more. That he did it as just a 20-year-old facing older competition in the Midwest and then California Leagues (between which he split his season almost precisely) is more impressive. Owing to elbow trouble followed by a Tommy John procedure, Alcantara made only three starts in all of 2014 — and the earliest likely return is the middle of 2015. Despite the lack of current data, however, the Steamer forecast still calls for run prevention at something slightly better than replacement level — best among Oakland’s rookie-eligible pitchers.
