David Ortiz is coming off A (unless my math skills fail me). I'm not sure what his contract status will be if traded, but since he was an E player in 1999, I am assuming he is at worst a B15. That would be 480K for a guy who hits 263/355/517.
The other carded player who I'm shopping is Tony Cingrani (B2), who might be of interest to rebuilding teams. 25 year old has very good K rates in both majors and minors, but wasn't very successful or very healthy in 2014.
I can also move cash and/or draft picks.
I am looking to contend again and would like to add one more playoff caliber starting pitcher.
