The Giants’ trade-deadline haul already looks like it could pay off in more than one way, and right-hander Miguel Mendez is suddenly the kind of arm worth watching closely. Acquired from the Padres in the Robbie Ray deal, Mendez is in position to get a real look when spring arrives, and San Francisco’s thin pitching picture gives him a lane to matter sooner rather than later.
Mendez made his @GoSquirrels debut in Bowie after coming off the IL, and the line was a clean one: 2.2 innings, 2 hits, 0 runs, 1 walk and 5 strikeouts on 50 pitches. His fastball reached 99. That kind of outing fits the profile the Giants are betting on.
The official MLB scouting report points to the growth behind the numbers. “Increased fastball velocity has fueled Mendez's climb, with his four-seamer sitting at 95-99 mph and touching 101 with explosive carry and significant armside run, the analysis states.
"Mendez also improved his control last year, enhancing his chances to remain a starter moving forward, though his strike-throwing still needs more work. He missed six weeks this year with shoulder and neck issues but returned just before the Deadline.
Even if he winds up as a reliever, his fastball-slider combo could make him special in a shorter role.”
For now, the Giants view him as a starter, even if the bullpen might eventually prove to be the better fit. Either way, the organization sees enough arm talent to keep pushing him forward.
Mendez will likely open the 2027 season at Triple-A Sacramento, but there’s a clear path for him to climb if he handles spring well. With San Francisco short on dependable rotation options, that opportunity is real.
Logan Webb is the one rotation name that looks secure. Beyond him, the picture is far less settled.
Carson Whisenhunt had been trending toward a role, but his UCL tear this week changed that fast. He’ll need Tommy John Surgery and is expected to miss likely most of 2027, which only opens the door wider for Mendez.
As one of Buster Posey’s key deadline pickups, the former Padres prospect may be one of the first pieces from that trade-deadline class to surface in the majors. What he does with the chance is still to be determined.

Giants Injury Crisis Could Force A Veteran Move Fans Didn't Expect
The Giants have spent much of the 2026 season piecing together a roster that has been battered on both sides of the ball, with injuries hitting position players and pitchers alike. In response, the front office has already cycled through plenty of roster moves just to keep the club afloat, and now the search for help appears to be widening beyond the usual internal fixes.
Among the veteran names being discussed are Eugenio Surez, Michael Lorenzen, Zack Littell and Austin Slater, a group that would give San Francisco more depth and flexibility as the injury problems continue. It is the kind of backup plan teams rarely want to lean on for long, but for a Giants club trying to stabilize the daily lineup and the pitching staff at the same time, the need for reinforcements is becoming impossible to ignore.

Giants Infield Shuffle Could Mean More Than A Buddy Kennedy Exit
Bryce Eldridge is back with the Giants after a brief stay on the bereavement list, and the roster move that made room for him sent Buddy Kennedy off the 40-man roster. It is the kind of infield shuffle that can look routine on the surface, especially for a player like Kennedy, who has hit much better in Triple-A than he has in the majors and has spent much of this season fighting for a foothold.
The wrinkle for San Francisco is what comes next, because Kennedy has already used up his option years and now has to go through waivers. If another club claims him, the Giants lose a depth piece they clearly had room for only in the short term; if he gets through, his past outright assignments give him the ability to choose free agency, leaving his future tied to a process the Giants cannot fully control.

Giants Already Have One Painful Question About That Red Sox Trade
The early returns on the Red Sox-Giants swap have been impossible to ignore from San Franciscos side. Marcelo Mayer still has not made his Giants debut because of injury, while Erik Miller has settled quickly into Bostons bullpen and has not allowed an earned run in his first 10 appearances. For a deal built around a high-upside prospect and immediate major league help, the contrast has been stark enough to make the trade feel like a live conversation rather than a finished transaction.
Millers underlying numbers have only sharpened the point, with a strong FIP and a strikeout rate that suggest the Red Sox may have found a real late-inning arm. Add in three more seasons of team control, and Bostons end of the deal suddenly looks even more valuable if Miller keeps pitching this way. For the Giants, the question now is whether Mayer can get on the field soon enough to keep this from becoming the kind of trade that looks harder to defend with every passing week. [Read more 🡒]
