Out of the Past Posted April 22, 2008 Share Posted April 22, 2008 I wanted to see how Hanley is doing defensively this year compared to last year. Defensive stats all have flaws but I think the best ones are the Revised Zone Rating (RZR) and Out of Zone (OOZ) published by the Hardball Times. They suggest to use both stats together. I decided to combine them and see where Hanley ranks this year compared to last year. The RZR simply calculates the plays made divided by the balls in his zone. The OOZ are the plays made by a player outside his zone. I adjusted the RZR by difference between the OOZ plays made by a player compared what the average player would have made. For example, Jeter has made 19 out of 24 plays in his zone for a .792 average and has made 9 plays outside his zone in 117 innings (one every 13 innings). The average player has made one play out of his zone every 25 innings so the average player would have made 4.7 OOZ plays in Jeter's 117 innings. To adjust his RZR for his proficiency in making plays OOZ, I added 4.3 to Jeter's 19 plays made in the zone and came up with the adjusted RZR. I did the same for all the qualified SS in both '07 and '08. In '07, Hanley ranked 24th out of 25 qualified SS with an adjusted RZR of 74.3%. In '08, Hanley ranks 4th out of 28 qualified SS with an adjusted RZR of 93.3%. The sample size is small but that's a pretty dramatic improvement.
