Wednesday's Hollywood ending to the postseason is the formal beginning of offseason business for the Rays, who are expected to have a busy winter.First up is free agency, which is formally granted this morning for eight Rays: starter Alex Cobb; 1B/DH Lucas Duda and Logan Morrison; relievers Steve Cishek, Tommy Hunter and Sergio Romo; OF Peter Bourjos; and INF Trevor Plouffe.The Rays have what amounts to an exclusive window to re-sign then until 5 p.m. Monday, when players are free to sign elsewhere. No pre-emptive deals are expected. By Monday, the Rays also have to decide on — and are expected to go ahead with — making a one-year, $17.4 million qualifying offer to Cobb, essentially hoping that within the allotted 10 days he turns it down, allowing them to get draft pick compensation when he signs elsewhere.As those eight players come off the 40-man roster, the Rays have to reinstate four from the 60-day DL: INF Matt Duffy and pitchers Nathan Eovaldi, Taylor Guerrieri, Shawn Tolleson (who might be released after missing the full season and is recovering from Tommy John surgery).The Rays also are expected to shortly hire a first base / assistant hitting coach, with Triple-A hitting coach Ozzie Timmons among the candidates.KEY ANALYST OUT: Noted pitching analyst Josh Kalk, an industry expert in PITCHf/x data and injury prevention studies and modeling, has left the Rays. Kalk, said to be pursuing other opportunities, joined the Rays in March 2009 as a research and development analyst, and in December 2015 was promoted to director of pitching research and development.Game 7 tidbitsThe Dodgers turned to pitching legends Don Newcombe and Sandy Koufax for ceremonial first pitches before Game 7 of the World Series on Wednesday against the Astros.
