As always, just like with scouting, it is always important to keep context in mind with these stats. A pitcher who is old for his level using that experience to succeed against young, inexperienced hitters must be taken with a grain of salt; the same goes when looking at these WAR totals.
But it is a useful tool to put each player’s performance into context and look at where they sit in regard to the rest of the league.
As a reminder, a 0.0 WAR per 162 games is replacement level — otherwise known as the kind of performance an average player from the level below could offer — a 2.0 WAR per 162 games is average, and a 5.0 WAR per 162 games is All-Star level.
Also, the lack of good defensive metrics for the minor leagues means we have to adjust for a range of defensive abilities. To account for this, I will give you each player’s WAR with a qualifier: either poor-defense WAR for a poor defender (-10 runs below-average per 162 games), average-defense WAR for an average defender (0 runs per 162 games), or great-defense WAR for a great defender (10 runs above-average per 162 games).
Additionally, note that pitchers have FIP-based WAR — which is based on peripherals like strikeouts, walks, home runs, etc. — and RA-based WAR — which is based on runs allowed.
One more thing, all “+” stats are averaged at 100. Anything over 100, like 110, is higher and means that player is 10 percent better than the league average. Anything under 100, like 90, is lower and means that player is 10 percent worse than the league average. In the case of any “-” stats — when lower is better, like with ERA — a 90 ERA- means that player is 10 percent better than the league average.

The WAR Room featured outfielder Bradley Zimmer last week, which would typically mean someone else would be highlighted here. But with Zimmer putting up Mike Trout-level numbers through 10 games — headlined by 0.7 average-defense WAR and a .324 isolated power (299 ISO+) — the outfielder is able to break the mold. Zimmer’s early-season surge is not really a BABIP mirage as his .320 BABIP (109 BABIP+) is perfectly normal and the outfielder is not showing a ton of swing and miss either (20.0% strikeout rate, 106 K%+). Just a dozen or so games into his full season career, Zimmer is doing nothing to dissuade the organization from thinking he is ready for the challenge of Double-A. Read More…
