A comparison of career, 162-game averages for three second basemen who were in the news on Wednesday:
*Runs Created Per 27 Outs (over career)
The first guy, of course, is 32-year-old Cubs second baseman Mark DeRosa, who will become Cubs "super sub" Mark DeRosa if the team consummates the endlessly rumored deal for the second guy, the Orioles' 30-year-old Brian Roberts, in a transaction that seems likely to cost the Cubs young pitchers Sean Gallagher, Sean Marshall, and more.
And the third guy? The often injured Marcus Giles, just 29 years old, who cost the Colorado Rockies next to nothing when he signed a minor league deal with the National League champions on Wednesday.
