Yes. UZR = the number of runs above (or below!) average a player is at his position. UZR/150 is the same, per 150 games played.

I never knew what the equation was to figure out WAR. I tried looking it up, but I couldn;t find anything official. I know it has to do with how many wins a player creates for their team over the course of a season, compared to a replacement player.
First you have to translate wOBA into runs.

From Fangraphs (link for full article):

Quote:
The other great advantage wOBA has is that it’s extremely easy to convert into run values. Simply take a player’s wOBA difference from the league average, divide by 1.15, and multiply that by how many plate appearances he got, and you have a run value above or below average for that player.
So to use Rajai Davis as an example.

.354 wOBA in 2009
.354 - .332 (league average OBP, which wOBA is scaled to) = .022
.022 / 1.15 = .025
.025 x 432 PAs = 10.9 runs above average.

10.9 runs as a hitter + 11.3 runs as a fielder = 22.2 runs above average total, which is 2.2 WAR

However, you also have to factor in replacement value, which is set at 20 runs per 600 PAs. The point of this is to assume that the time the player isn't on the field, he's substituted by a replacement level player. Since Davis had 432 PAs, he gets 432/600 worth of that 20 runs. 432/600 = 0.72, so you take 20 * 0.72 and get 14.4.

He also gets a slight positional bonus because he played centerfield (2.5 runs) but he didn't play a full season so he only gets 1.4 runs.

So: 10.9 (hitting) + 11.3 (fielding) + 14.4 (replacement) + 1.4 (fielding adjustment) = 38 runs.

10 runs = 1 WAR, so Rajai Davis was a 3.8 WAR player in 2009.

-------------------------------------------------------------------------

*EDIT*

So, to put this into OOTP terms, you could calculate some sort of WAR value assuming the ZR can be (or is) calculated as runs above/below average. However, you'd also have to figure out what replacement level is for whatever league settings you are using.
