Dan Szymborksi's 2013 ZiPS projections are being released on FanGraphs this year, and they posted the Reds this morning:

Something of which people never tire is to learn that there is both good news and also that there’s bad news. The bad news, in the case of the Cincinnati Reds, appears to be — at least so far as Dan Szymborski’s finely calibrated ZiPS projection system is concerned — appears to be that newly acquired Shin-Soo Choo is probably a pretty bad defensive center fielder. The good news, though, is that he’s still expected to be worth about three wins in 2013 — i.e. more than he produced in either 2011 or -12.
