Willy Adames gives the Giants a winter decision that is simple on the surface and a lot messier once you get into the details. San Francisco should bring him back and open 2027 with him at shortstop if he’s healthy. The real issue is how long the club can keep rolling with him there if the defensive problems that showed up in 2026 don’t go away.
The glove is the part that changed the conversation. Statcast had Adames five outs above average at shortstop in 2025, then 17 below average in 2026, which tied him for the lowest mark in the Majors. That kind of drop puts a spotlight on every ground ball and every throw.
The bat was steadier, even if the overall line still left plenty to want. Adames hit .230/.289/.424 in 2026, after .225/.318/.421 the year before. His slugging stayed about the same, but his walk rate slid from 11.7% to 7.3%.
There were health issues in the mix, too. Adames dealt with back trouble before a left elbow sprain ended his season in August. Buster Posey pointed to the back issue when he backed Adames as the Giants’ shortstop.
Even with the uneven year, Adames still managed 21 home runs in 121 games. If the defense snaps back, that kind of power plays at a premium position. In camp, the Giants need to pay close attention to how he handles ground balls on both sides and how cleanly he finishes throws while moving.
Money makes the whole thing harder. Adames is owed $140 million in base salary over the final five years of his deal, and any trade would need his approval because of the contract’s full no-trade clause. After a down season and with that much salary left, a quick trade partner would not be easy to find.
That’s why Marcelo Mayer matters in this picture. The Giants should give him regular shortstop innings in spring training.
He started 20 games there for the Boston Red Sox in 2026 and played six games for San Francisco after the August trade. A left forearm injury pushed back his Giants debut until September, and he still needs real at-bats and defensive reps before the club can trust him with the job.
If Mayer needs more time, San Francisco could look for a veteran who can back up shortstop and also cover second and third. Edmundo Sosa is one free-agent option that fits that description.
The first few weeks of the season should tell the Giants plenty. After six to eight weeks of healthy regular-season play, they should reassess Adames’ range, throwing and walk rate.
If the defense comes back and the on-base percentage stays near .289, batting him sixth or seventh would keep his power in the lineup while opening more plate appearances for hitters who get on base more often. If the range still isn’t there and Mayer is ready, the Giants should split the shortstop starts.
There’s also the possibility of trying Adames at second base in camp so the team can see how that alignment looks. That move would have to lift the infield enough to justify taking starts away from Casey Schmitt or another second-base option.
And if both the bat and the glove stay stuck, the Giants may have to cut back his starts and find out whether he’d consider a trade before the deadline. That only makes sense if he approves it and the return brings either real salary relief or a player who fills another need on the roster.

Giants Catcher Depth Problem Leaves Familiar Name In The Mix
The Giants catching picture has been unsettled enough this season that a familiar face is suddenly back in the conversation. Andrew Knizner returned to the organization after opting out of a minor league deal with the Boston Red Sox, giving San Francisco another experienced option at a position that has been thinned out by injuries and roster shuffling.
Knizners stint with the Giants covered 29 games, and his production looked a lot like what the club already knew from him a year earlier. After the season, San Francisco put him on waivers, then outrighted him to Triple-A when no one claimed him, and he is expected to elect free agency. Even so, a return on another minor league deal is still on the table, which leaves the Giants with one more familiar name in a spot they clearly still need to sort out. [Read more 🡒]
Giants Infield Crunch Just Put Christian Koss On Notice
Christian Koss spent most of 2026 trying to carve out a place in the Giants infield, and he did enough to stay in the conversation. He appeared in 70 games, mostly at shortstop, but the season also showed the limits of his current role. The bat was light, with a .217 average, four home runs and 12 RBIs, and the defensive side brought its own challenges as he tried to hold down a spot on a crowded roster.
The squeeze only gets tighter heading into 2027, with newly acquired infielder Marcelo Mayer joining a group that already includes Matt Chapman, Willy Adames and Casey Schmitt. For Koss, the issue is no longer just whether he can stick around, but where the opportunities will come from if the Giants start sorting out playing time differently under Tony Vitello. In a situation like this, every spring rep matters, and every mistake can shift the depth chart a little more. [Read more 🡒]
Giants Suddenly Have A Real Center Field Question This Offseason
Harrison Bader is back on the Giants 40-man roster with one year left on his contract, but the bigger question this offseason is whether he can be counted on to handle a regular center field workload. Bader missed most of the 2026 season because of a left foot injury and the related setbacks that followed, leaving San Francisco to sort out a position that looked settled not long ago.
Drew Gilbert has emerged as the likeliest answer if Bader needs more time, after starting 83 games in center field in 2026. Jonah Cox gives the Giants another layer of depth, but the clubs center field picture now hinges on how much Bader can rebound and whether Gilbert is ready to carry the job for a full season.
