The San Francisco Giants have not been flashy this offseason, but it does not mean that moves are not being made.

The club recently signed free agent right-hander Adrian Houser for a two year, $22 million deal to supplement the starting rotation. Also, there have been moves to stack the bullpen with various arms that can be considered reclamation projects.

The Giants now have multiple relievers who, if not for injuries, could be commanding a lot more attention right now. Instead, they have come to San Francisco to try and revitalize their careers. Recently, Grant Brisbee of The Athletic identified who these relievers are, and two of them are featured below.

Brisbee started with Gregory Santos, a right-hander who finds himself back in a Giants uniform after spending the 2021 and 2022 season with the club.

"Santos was an “if he could just harness his stuff” champion," Brisbee wrote. The Giants got tired of waiting, though. They traded Santos to the White Sox after the 2022 season, and in 2023, he put up an excellent season for them, with a 3.39 ERA (2.65 FIP) in 60 appearances.

"His walk rate dropped dramatically, and he looked like a high-leverage arm that the Giants regretted losing. " After arthroscopic knee surgery in April, now he’s back on the Giants on a minor-league deal, and he’s still just 26 years old and in possession of a live fastball."

Santos only made five appearances during his first stint in San Francisco, so most of his reps came over the last three seasons. In 81 career appearances, Santos has a 3-6 record with a 4.17 ERA. Perhaps now, he will produce the results the Giants are hoping for.

Another name on Brisbee's list is Sam Hentges, who spent the first four years of his Major League career with the Cleveland Guardians.

"The best way to explain Hentges (and the concept of building a bullpen in general) is that if he were a free agent after the 2022 season, he would have made $30 million, easy. If he were a free agent after the 2023 season, he might not have made as much guaranteed money, but he still would have netted a multi-year deal."

"However, he missed most of the 2024 season following shoulder surgery, and during his recovery, he also injured his knee, which cost him the 2025 season. I think there should be a “throws harder than 95” union, where the relievers who get those $30 million contracts kick a little down to the pitchers who didn’t get the same fortuitous timing with their free agency. Get them a gift card, at least."

In 168 career games, Hentges, 29, has a 7-8 record and a 4.18 ERA. Both Hentges and Santos have potential and are under 30, giving San Francisco a chance at low-risk, high reward arms.
