The San Francisco Giants have plenty to sort out on the mound this winter, but one move they should resist is the easy one: chasing Zac Gallen because of who he used to be.
That’s the danger of free agency. A pitcher can string together a few standout seasons, build an All-Star résumé, and suddenly the market starts paying for the name on the back of the jersey instead of the numbers on the page. Gallen fits that warning sign right now.
Not long ago, he looked like one of the most dependable starters in baseball. He finished third in National League Cy Young Award voting in 2023 and was a key part of Arizona’s run to the World Series. For a stretch, he was one of the more recognizable arms in the division.
That version of Gallen is hard to find now.
After a 4.83 ERA in 2025, he went back to Arizona on a one-year, $22.025 million deal, apparently with the goal of rebuilding his value before hitting the market again. Instead, his 2026 season went sideways.
He posted a 6.07 ERA over 105 1/3 innings, gave up 71 earned runs and struck out only 64 batters. His 1.547 WHIP was another ugly marker, and it was a career high.
The trouble didn’t stop there. An elbow injury landed him on the injured list in July, and he finished with just 20 starts. The year before, he had made 33.
San Francisco’s need for pitching is obvious. Logan Webb gives the rotation a real anchor, but injuries have shredded the rest of the group. The depth chart has become so thin that Buster Posey’s rotation looks more like a construction site than a finished product.
That’s why Gallen could show up on the Giants’ radar. The name still carries weight, and a down season could push his price into a range that looks appealing. But the Giants have already lived through the pain of betting big on players who couldn’t deliver what the contract asked for.
There is a version of this where the fit makes sense. If Gallen comes cheaply on a short-term deal, he gets a chance to rebuild his value, and the Giants avoid tying themselves to a long commitment.
Anything more than that starts to look like a mistake.
The Giants don’t need the pitcher Gallen was in 2023. They need someone who can help in 2027, 2028 and 2029. Right now, he hasn’t shown enough lately to make that feel like a safe bet.

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.
