There was little doubt that the Astros were interested in retaining the services of free-agent Michael Brantley this offseason. The feeling appeared mutual from the five-time All-Star. Only the status of Brantley’s surgically repaired right shoulder — or a surprising suitor willing to offer money and security — could plausibly deter the two parties from reaching their third agreement in four years. After all, it likely wouldn’t take much to re-sign a 35-year-old left fielder and part-time DH coming off shoulder surgery, even in this market. As long as Brantley’s overall health checked out fine and the financial terms were amiable, it felt like only a matter of time before an agreement was made public.
