One name to watch, according to Jon Paul Morosi of FOX Sports (via Twitter) is Padres right-hander Luke Gregerson. The 28-year-old could appeal to clubs as he has a 3.05 ERA with 9.5 K/9 and 2.6 BB/9 on the year. While Gregerson could be a valuable trade chip for San Diego, the Mets reportedly turned down a proposal that would have sent Gregerson to Queens for Daniel Murphy.
