In previous posts, I looked at the Revised Zone Rating (RZR) and Out-of-Zone Plays (OOZ) metrics listed at FanGraphs.  Links to these posts are provided below:
Now, I'm going to to do the above conversion for left fielders.  Table 1 below contains the following information for left fielders with 800 or more innings in 2014: 
  • Inn = Innings
  • RZR = Revised Zone Rating
  • OOZ = Out-of-Zone Plays
  • PIZAA =  Plays in Zone Above Average
  • OOZAA = Out-of-Zone Plays Above Average
  • PMAA = Total Plays Above Average
  • RSAA = Runs Saved Above Average
Royals left fielder Alex Gordon was the MLB leader in RSAA (+23) followed by Christian Yelich of the Marlins (+22).  Both outfielders were better on out-of-zone plays than in-zone plays: Gordon (+24 PIZAA, +4 OOZA) and Yelich (17, 10).

The worst left fielder according to these metrics was Domonic Brown of the Phillies with -19 RSAA.  He was +1 on plays in the zone, but -23 outside the zone.  

Two Tigers outfielders had positive results playing less that 700 innings in left field: Rajai Davis (+8 RSAA) and J.D. Martinez (+4).  Keep in mind though that defensive measures are not reliable with small sample sizes.
