Christian Koss spent much of the Giants’ season in the background, but that doesn’t make his situation any less precarious now. His fate on the roster is no longer in his own hands, and after the year he just had, there’s no guarantee the Giants will keep betting on familiarity.
Koss got his biggest run when the injuries piled up and Casey Schmitt, Willy Adames and Matt Chapman all landed on the injured list. That pushed him into an everyday role in September, and he ended up appearing in 70 games overall.
Last season, he looked like a useful piece with 1.8 WAR in 74 games. This year was a different story entirely.
The numbers were brutal. Among the 135 qualified hitters in 2026, Ezequiel Tovar finished with the lowest OPS at .617.
Koss wasn’t far behind at .562, along with a 58 wRC+. His final five games summed up the slide: 1-for-16 with 10 strikeouts and no walks.
The glove helped at times, but not enough to erase the damage at the plate, and FanGraphs had him at 0.0 WAR.
That leaves the Giants weighing whether the default option is still worth keeping. Koss probably enters the winter with some kind of edge simply because he’s already there, and because so many other pieces are unsettled.
But that edge looks thin. Marcelo Mayer, despite his own rough showing at the plate, offers a higher offensive ceiling and could push into the backup middle infield role next season.
That outcome, though, depends on how the Giants handle the rest of the middle infield. Casey Schmitt or an outside addition such as Luis Arraez could take over at second, with Adames at short and Mayer backing up.
If Schmitt winds up spending more time in left field, the picture changes again. The sense is that Schmitt is more natural in the infield and would help the club more there, but if Harrison Bader leaves and the Giants don’t add outside outfield help, Schmitt could log plenty of innings on the grass and create another opening for Koss.
Left field already looks unsettled. A Bo Davidson/Victor Bericoto platoon could be the answer there, or the Giants could turn to a Turner Hill/Schmitt platoon. Either way, the position doesn’t have the kind of fixed answer it once did with Heliot Ramos, and the source material notes that, with the way he played for the Yankees, hindsight suggests he was no great miss anyway.
What makes Koss’ position even shakier is the sheer volume of roster churn coming. The Giants currently have 57 players on the 40-man roster because so many are on the 60-day IL, which means 17 players will have to be cut loose through waivers or outright releases. In that kind of squeeze, Koss is hardly a safe bet.
Maybe the Giants still like what they see in him long term. Maybe they don’t. Right now, all that’s certain is that Koss has run out of chances to make the case himself, and his future will be decided by the moves Posey makes - and doesn’t make - over the next few months.

Giants Fans Already Have A Krukow Successor Debate Brewing
Mike Krukows impending retirement after the 2026 season has already put Giants fans into speculation mode, because filling that chair will not be a simple handoff. Krukow has been one of the defining voices of the franchise, and now the conversation has turned to who might fit the job when the Giants eventually have to replace him.
J.T. Snow has already said he has interest in the role, and he is far from the only name floating around. Hunter Pence, Javier Lopez, Shawn Estes, Rich Aurilia, George Kontos, Sergio Romo, Jeremy Affeldt and Dusty Baker are all among the possible candidates, and the Giants are expected to look at multiple options before making a decision. For now, it is less about a single frontrunner than a familiar question around this team: who can step into a role that means so much to the fan base? [Read more 🡒]
Buster Posey May Revisit A Giants Path Fans Know Well
Buster Posey spent the 2026 season focused on shaping the Giants future, even as the roster swelled to a record number of players and the club ultimately finished fourth in the NL West. The front office still found a way to add to the next wave, using the MLB Draft to bring in pitching prospects, but the bigger work this offseason could come in the form of familiar names.
Several former Giants are now free agents, and that opens the door to a path fans know well: revisiting players who already have history in San Francisco. Kevin Gausman, Luis Arraez, Robbie Ray and Michael Conforto are among the possible additions the Giants could weigh as Posey looks to keep improving a roster that still needs more certainty, even after an active year of turnover and prospect accumulation.

Grant McCray May Already Be Losing His Place In The Giants Outfield
The Giants are heading into the winter with more outfield names than obvious openings, and Grant McCray is suddenly one of the players whose future feels the most unsettled. With Drew Gilbert, Jonah Cox, Bo Davidson, Jung Hoo Lee and Harrison Bader all in the mix for 2027 roles, San Francisco has plenty of competition on the grass, and McCrays appeal has to be weighed against the reality of where he fits in that crowd.
McCray still brings speed and the kind of minor-league flexibility teams like to keep around, but the Giants also have to decide how much patience to give a player whose 2026 offense and defensive numbers did not do much to strengthen his case. That has made an offseason trade a real possibility, though keeping him at Triple-A is still on the table if the market does not cooperate, which leaves his status as one of the more interesting roster questions on the board.
