Most Doubles Allowed in a Season

This follows the previous post by looking at the most doubles allowed by a pitcher in a single season. There's a lot of recent seasons on the list. Who would've thought that five of the only fifteen 60+ doubles allowed seasons in the past half century took place in 2006 or 2007? I like it when I can pick an arbitrary cutoff at a nice number: only twenty-five pitchers have given up 58 or more doubles in a season (since 1957).

I guess you have to be pretty durable and usually play in front of a bad defense (cough...Milwaukee...cough) to make the list.
