The Los Angeles Dodgers have the arduous task of replacing Zack Greinke after the right-hander suffered a broken collarbone in a bench-clearing brawl on Thursday night (via ESPN.com). Ted Lilly will presumably fill the rotation void initially, but there are other internal and external candidates to consider.
Free agents like Roy Oswalt and Carlos Zambrano could still contribute despite their forgettable 2012 campaigns. However, neither cracked this top-five list.
We seldom see blockbuster trades around this time of the season because, in most cases, MLB teams believe they still have opportunities to contend. Even the bottom-dwelling Chicago Cubs and Miami Marlins would hesitate to move starting pitching as they deal with their own injuries.
The Dodgers ought to speak to the lowly Houston Astros in the coming days. Otherwise, we'll probably see them scour their own farm system or stretch out a reliever.
