The Giants’ 2027 offseason checklist starts with the pitching staff, and it doesn’t stop there.
San Francisco went 65-97 and finished fourth in the National League West, leaving President of Baseball Operations Buster Posey with a roster that still has too many unsettled spots. Rafael Devers, Willy Adames, Matt Chapman, Casey Schmitt and Bryce Eldridge are expected back in 2027, but deadline moves and injuries have left the rest of the group in flux.
The biggest issue is the rotation. After trading Robbie Ray and Tyler Mahle, the Giants could really only pencil in Logan Webb and Landen Roupp as established starters for next year.
Webb’s season ended with a blister, and the organization is also facing a wave of injury-related uncertainty: Hayden Birdsong, Trevor McDonald and Carson Whisenhunt are expected to miss much of 2027 after Tommy John surgery, while Blade Tidwell’s late-season elbow injury created another problem. Anthony Molina put himself in the conversation for a rotation spot, and there are other young arms worth a look, but Posey still needs at least one proven starter and another reliable innings source.
The bullpen comes next. San Francisco entered its final series with a 4.18 bullpen ERA and no clear answer on who would handle the biggest late-game spots.
The club brought Camilo Doval back in September, but that only shifted the conversation into an arbitration decision instead of settling the closer role. Ryan Walker also spent time at Triple-A after struggling, and Randy Rodríguez is coming back from Tommy John surgery.
Trent Harris emerged as a promising internal option, but the Giants still need another dependable late-inning arm and enough depth to absorb injuries. Whether Posey targets a closer, a setup man or both, relief pitching remains a priority.
The outfield is another area that needs real answers. Jung Hoo Lee is still part of the picture, but Heliot Ramos was traded to the Yankees and Harrison Bader’s injuries interrupted his first season with the Giants.
Drew Gilbert, Jonah Cox and Bo Davidson give the club some options, with Davidson reaching the majors in the final week, but that group still doesn’t equal a settled everyday alignment. A healthy, established outfielder who can help both at the plate and in the field would take pressure off the younger players, and the Giants also have to decide how much they want to count on Bader returning.
Second base is still open too. Luis Arraez’s departure created the vacancy, and Marcelo Mayer arrived at the deadline as a possible long-term answer.
Injuries slowed his first stretch with San Francisco, and when he returned in September, he initially appeared as a designated hitter. Schmitt’s versatility gives the Giants another route once he comes back from knee surgery.
Posey doesn’t have to lock in a permanent starter right away, but he does need to find out whether Mayer is ready and identify a dependable fallback if he isn’t.
Before any of those pieces can be added, though, the Giants have to make room. San Francisco is dealing with players returning from the 60-day injured list, and Giants On SI previously reported that the club was looking at 55 players under team control for 40 spots. Fringe players, injured veterans and arbitration-eligible relievers will shape how much flexibility Posey has for acquisitions and prospects.
Catching is lower on the list because the Giants have Daniel Susac, Jesús Rodríguez and Drew Cavanaugh in the pipeline. The more immediate challenge is simpler: clear the roster, then use the space to add enough pitching and outfield production to support the young core.

Giants Face Awkward Zach Morgan Question Heading Into The Offseason
Zach Morgan spent about 10 days on the Giants active roster this season, getting called up twice and never actually getting into a game. Even with a chance to find him a role late, including the final weekend of the year, San Francisco never brought him back onto the field, leaving his time on the big-league roster as more of a roster-management footnote than a true audition.
Now the Giants have to sort through a crowded offseason picture at catcher and elsewhere on the 40-man roster, with injured-list decisions also hanging over the mix. Morgan is part of that broader puzzle, and the question is no longer just whether he can help, but whether the Giants see enough of a path to keep carrying him through the winter. [Read more 🡒]
Giants Suddenly Have Two Rotation Hopefuls Worth Watching Closely
The Giants spent much of the season fighting through a pitching staff that never quite held together, and the injuries and thin depth were a big reason they finished fourth in the NL West. Even so, the late surge from Matt Wilkinson and Anthony Molina gave the organization something to circle going into the offseason, with both pitchers showing enough promise to at least get themselves into the conversation for spring training.
Tony Vitello already noted that Wilkinson could help in more than one role, whether as a starter or in a long-relief job, and that kind of flexibility matters for a club still sorting out its rotation picture. Molina is in the mix too, which gives San Francisco two younger arms worth tracking as camp opens and the Giants try to turn a troublesome season on the mound into a more stable one. [Read more 🡒]
Giants Face A Tough Pitching Decision They Cant Miss
The Giants offseason already has a familiar shape to it: protect the rotation and bullpen depth without boxing themselves in financially. After a season that left real questions about pitching depth, the front office is weighing how much value to place on dependable innings and roster flexibility as it sorts through its free-agent and arbitration decisions.
JT Brubaker fits the kind of modest, practical move the Giants can make to keep the staff insulated from injuries and attrition, while Camilo Doval presents the tougher call. His inconsistent 2026 performance and arbitration price tag put the club in a bind, and the next step there will say plenty about how aggressively San Francisco intends to manage payroll while trying to avoid another thin pitching season.
