In 20 years, the Arizona Diamondbacks have had a total of 60 player-seasons, by 30 different men, where there were 10 or more stolen-bases. There were four this year, two off the franchise record of six, set in 2011. At the other end, there was only one man in 2004 with ten stolen-bases. If you can remember who that was, without looking it up, you have a better memory that I do! [Mind you, this may just be a defensive mechanism: I have to suppress the urge to curl up in the fetal position and start sobbing, any time I have to remember the 2004 season...]
On an individual level, two currently share the lead with five such seasons. One is a current Diamondback, one former: they never did it the same year, though did overlap in one season. 17 of the 30 were “one and done,” and that’s likely where the greatest trouble is going to be found. As the intro suggests, there were a couple of names to be found which quite surprised me. Nailing 55 of the 60 seasons would be the target score here, I think. As usual, last names only are fine: link for mobile, if what’s below is not working for you.
