The Cubs had a big problem in 2009 at 2nd base. We all thought Mike Fontenot would beat out Aaron Miles for the starting job, which he did, but it turned out that Fontenot was somewhat of a bust. Miles played horrible all year so he didn't do the Cubs any good either.
On July 2nd the Cubs got Jeff Baker from the Colorado Rockies to take care of the problem at 2nd. For the most part he did a pretty good job. He batted .305 for the Cubs in 2009 in just 69 games. The problem is, is he has never a played a full season. He is expected to be the everyday starter for the Cubs in 2010. In 2008 he batted .268 in 104 games, which is the most games he has played in a season during his career. Mark DeRosa, on the other hand, batted .285 in 149 games for the Cubs in 08.
Mark DeRosa doesn't just hit better than Baker but he can run better. DeRosa had 6 SB and 2 CS while Baker had 1 SB in 09 with 0 CS. This was a problem with the Cubs last year, they had no one to steal bases. Now I'm not saying DeRosa is Ricky Henderson but he will get some needed SB for the Cubs.
If DeRosa was back with the Cubs then he could play 2nd. He could back-up Lee at 1B (depending on the status of Micah Hoffpauir this off-season), He can play an excellent LF, which was really needed last year. Plus, he can play 3B. So we know he is versatile so why not get him?
There is speculation that Starlin Castro will earn a spot in Spring Training which could move Theriot to 2nd. I doubt Castro makes the big leagues this year before September.
Guys who could also play 2nd base for the Cubs in 2010 besides Baker, Fontenot, and DeRosa are Felipe Lopez, Orlando Hudson, Adam Kennedy, and Ronnie Belliard. To me it's either DeRosa or Hudson, but out of the 2, I choose DeRo.
