However, that hasn’t necessarily been the case. The first addition has been southpaw Sam Hentges, who is coming off of a significant shoulder surgery, despite being effective earlier in his career. The second is Jason Foley, who won’t be available until the back half of the season.
Due to the group looking eerily similar to the end of the 2025 season, they’re projected to be one of the worst bullpens in baseball. According to FanGraphs, the Giants can expect 1.1 fWAR from their entire bullpen. While projections are often wrong, that ranks 28th in all of Major League Baseball.
If the Giants want any chance at contention in a tough National League, they’ll need to add some more certainty to the group or hope for some huge strides from a few of the young arms. Let’s take a look at the best options for San Francisco to upgrade this group prior to Opening Day.
Kopech’s had an interesting ride in MLB but it appears that he’s finally found who he is as a pitcher. While it was a limited sample in 2025, his 2.45 ERA was the best mark of his career by nearly an entire run.
He also brings two things to the table that the current Giants bullpen doesn’t have. For one, he has real experience closing games. Kopech’s 15 saves in 2024 would have nearly led the Giants bullpen in 2025 and with the ups and downs of Ryan Walker last year, that experience could go a long way.
Kopech also boasts overpowering stuff, something the current group can’t necessarily brag about. While he only throws two pitches, the fastball holds a Stuff+ rating of 117 while the cutter has a rating of 124.
Clearly, he could bring a bit of excitement to a group that desperately needs it as we inch closer to Opening Day.
Miller is coming off a truly impressive season at age 34. He threw his second-most innings since 2016 (46.0 IP) with a 2.74 ERA and 3.44 FIP.
