Marshall (shoulder) is expected to begin throwing again in six weeks, C. Trent Rosecrans of the Cincinnati Enquirer reports. Marshall underwent a shoulder procedure in mid-May that is expected to keep him on the shelf for the remainder of the 2015 season. The soon-to-be free agent will likely have to showcase for teams to prove he's healthy before getting much attention on the market. At 32 years old and with several noteworthy procedures under his belt, he'll likely have to catch on with a low-risk, team-friendly deal.
