[Dbacks.com] Rotation picture and more offseason questions for D-backs - 4. What to do about the bullpen? The bullpen was a huge strength for the D-backs in the second half of 2023 and during their postseason run to the World Series that year. Almost the same cast of characters returned for '24 and the results were, well, not as good. Paul Sewald will likely depart via free agency, but the club can bring back Ryan Thompson, Kevin Ginkel, Joe Mantiply, A.J. Puk and Justin Martinez next year. Do the D-backs trust that group enough to make only marginal additions, or do they need to get an experienced closer?
