If the Giants are serious about fixing their rotation, they need to think bigger than a stopgap. One trade that fits the bill sends Reid Detmers from the Angels to San Francisco for Casey Schmitt, Bo Davidson and Ramon Marquez.
It’s a steep ask, and that’s the point. The Giants would be parting with a productive big-league infielder and two well-regarded prospects, but Detmers is the kind of arm that can justify that kind of hit. San Francisco has been framed as needing meaningful rotation help, and this would clear that bar.
Detmers delivered a strong 2026 season, posting a 3.36 ERA and 1.04 WHIP over 185 innings. He made 32 starts, struck out 211 and walked 48. For a Giants club looking to shore up the front of its staff, that mix of innings and swing-and-miss ability would be a real upgrade.
The appeal goes beyond one season, too. Detmers is under club control through 2028, and MLB Trade Rumors projects his 2027 arbitration salary at $7.5 million. That kind of contract structure would give San Francisco some breathing room as it tries to spread offseason spending around other needs.
He’d slot in next to Logan Webb and Landen Roupp and immediately lessen the pressure on injured pitchers to return quickly or younger arms to survive full workloads. The Giants would still need depth, but Detmers would give them another starter capable of taking regular turns near the top of the rotation.
Of course, there’s risk baked into the move. Detmers spent all of 2025 in relief before returning to the rotation, so San Francisco would be betting on the version that just held up across a heavy workload. The hope would be that his command gains and strikeout stuff carry over.
The price tag is what makes this trade complicated for the Giants. Schmitt brings power and real value at the major-league level, while Davidson is the kind of outfield bat who could push toward regular playing time. Giving up Schmitt would also mean the Giants need a real answer at second base, with a healthy Marcelo Mayer and dependable depth if he can’t handle the job.
For the Angels, the package works on multiple levels. Schmitt could step in at third base once Yoán Moncada’s one-year deal is done, while Davidson and Marquez would add younger talent with more runway. Denzer Guzman is still an internal option at third, but Schmitt would offer a more established bat.
Schmitt’s 2026 line gives the idea some real bite: 21 home runs and a .271/.301/.483 slash line in 98 games. He’s controlled through 2029, which makes him more than a bridge piece if his recovery from knee surgery checks out for the Angels’ medical staff.
Davidson, meanwhile, would cost San Francisco a left-handed outfield bat that looks close to MLB regular work. He hit .290/.361/.527 with 29 home runs across Double-A and Triple-A before making his September debut with the Giants. Losing him would remove a legitimate internal option for 2027.
Marquez adds a different kind of value. The 21-year-old posted a 2.22 ERA with 105 strikeouts in 69 minor league innings in 2026 and sits on MLB Pipeline’s Top 100 list. For the Angels, he would be a development bet with starter upside after moving Detmers.
That matters because the Angels already dealt José Soriano for three prospects in August. Trading Detmers would make their rotation thinner still, so any return has to help in the present and restock the future, especially on the pitching side.
They could always choose to extend Detmers instead, or push for a different package. But Schmitt, Davidson and Marquez would be enough to make this a legitimate offer. The Giants would be giving up real talent to land two years of pitching that fits the next version of their roster.

Giants Pitching Need Just Put This Offseason Market In Focus
With multiple pitchers in the organization rehabbing from Tommy John surgery, the Giants search for outside help this offseason is already taking shape around the arms they can realistically add. One area of focus has been Japan, where San Francisco has reportedly been scouting Hiromi Itoh and Karima Taira as possible pitching targets, a sign the club is casting a wider net as it looks for reliable innings and depth.
Itoh and Taira are not simple fits, though, and the process for landing either one is different from a standard free-agent pursuit. Tairas path would hinge on whether his Japanese club chooses to post him through the posting system, and so far there have been no signings confirmed, leaving the Giants with interest for now and plenty of moving parts still to sort out.

Giants Still Have Key Roster Gaps These Free Agents Could Solve
The Giants offseason shopping list still reaches well beyond the headline additions and into the kind of value signings that can patch over a long season. With depth in both the rotation and the everyday mix still in view, the club is looking at low-risk free agents who can soak up innings, move around the diamond and give the staff some matchup options without blocking the rosters higher-end pieces.
Cal Quantrill and Taylor Clarke fit the pitching side of that equation as possible one-year answers, while Isiah Kiner-Falefa and Randal Grichuk stand out as position-player fits who could add flexibility and a different look against certain opponents. The appeal is straightforward: none of these targets is being eyed as a marquee fix, but each could help steady a roster that still has a few gaps to cover before Opening Day. [Read more 🡒]
Giants Are Betting On Logan Webb After A Season Fans Can't Ignore
After a disappointing 2026 season, the Giants have made their direction clear by keeping Logan Webb in place rather than shopping their ace. It is a notable stance for a club that could have used a rough year as cover for a larger reset, but instead remains committed to building around the same core and keeping the roster aimed at contention.
Webbs season was uneven by his standards, with a 4.31 ERA in 27 starts and time lost to a knee issue, but San Francisco is still investing around him, especially in the bullpen and other key pieces. The choice says as much about the Giants expectations for 2027 as anything else, even if the questions around Webbs recent form are not going away anytime soon. [Read more 🡒]
