Last week, or maybe it was the week before, I was looking up something in "The New Bill James Historical Baseball Abstract" and came across a bit on Donie Bush, a Tigers shortstop in the Ty Cobb era. The Tigers won American League pennants in 1907, 1908 and 1909 -- Bush's first year as a regular -- but never won again despite talented teams. "One key reason they didn't win," James wrote, "was that Bush was awful at turning the double play. I'm sure there are teams which have won the pennant despite being unable to turn a double play, but frankly, I've never heard of any.
