What players had the biggest differences between their home and away walk rates?

I looked into this because I saw that Mel Ott walked 955 times in home games but only 765 in away games (and he had more PAs in away games). He hit 323 HRs in home games and 188 away. So maybe opponents wanted to be careful with him at the Polo Grounds where it was only 257 feet down the RF line (Ott batted left-handed).

I had Stathead call up all the players with 2,500+ PAs in both home and away games. Then I only looked at guys that were on both lists (924). Then I calculated walk% as walks/PAs

Here are the top 33 in Home walk%/Away walk%. I went down to 33 because Ott was 33rd. Tillie Walker and Rondell White are outliers. Walker hit 79 of his 118 HRs at home. White hit 124 of his 198 HRs in away games. So maybe there is no pattern.
