The Giants turned a roster squeeze into a little something on Friday, sending left-handed reliever Reiver Sanmartín to the Nationals and getting minor league right-hander Robert Cranz back in return.
It’s not the kind of deal that changes a franchise, and nobody is going to mistake it for a headline-grabber. But after Sanmartín was designated for assignment Monday, the Giants were staring at the possibility of losing him for nothing. Instead, they came away with a 23-year-old arm who has flashed enough in the minors to merit a closer look.
Sanmartín’s time in San Francisco wasn’t empty. He made 24 appearances for the Giants in 2026, logging a 4.22 ERA with 16 strikeouts over 21 1/3 innings.
He also finished stronger than he started, posting a 1.69 ERA across his final 19 outings. Even so, that late run wasn’t enough to keep him in the Giants’ plans.
Cranz, a seventh-round pick out of Oklahoma State in 2024, brings a different profile. He struck out 40 batters in 26 1/3 innings at Double-A this season and put up a 3.42 ERA there. The Triple-A numbers were far rougher - a 13.11 ERA in 11 2/3 innings at Rochester - which makes it clear there’s still work to do.
For the Giants, the appeal is simple: they didn’t let a pitcher walk away for nothing. Cranz may wind up in Sacramento next season, or elsewhere in the system, but he gives San Francisco another development project instead of an empty loss.
That said, this move barely dents the bigger issues in front of the club. The Giants still need proven pitching and healthier players who can help them compete again, and a minor league reliever won’t move the projected win total much at all.

Victor Bericoto Is Giving The Giants A Real Outfield Dilemma
Victor Bericotos strong run in the Venezuelan Winter League has given the Giants something to think about as they sort through their outfield picture for next season. He has been hitting .391/.513/.672 with four home runs and 21 RBIs in 17 games, production that has quietly put him on the radar at a time when San Francisco is weighing how much depth it really needs in the grass.
The Giants already have several outfield options in house, but Bericotos winter surge adds another name to a conversation that could still go in a few different directions. They can lean on the players already in the organization or look outside for a veteran addition, and his performance is at least making the internal debate a little more interesting than it was a few weeks ago.

Giants Face A Tough 40-Man Crunch They May Not Escape Soon
The Giants are staring at a roster squeeze that has been building for months, and it is not hard to see why. Six pitchers on the 40-man roster have undergone Tommy John surgery in the past 14 months, a reminder of how much of the clubs pitching depth is tied up in long recoveries rather than immediate innings.
Randy Rodrguez has already started a rehab assignment in the Arizona Fall League, while Rowan Wick remains in the organization after his team option was declined and he now waits on a non-tender decision. Hayden Birdsong, Trevor McDonald, Carson Whisenhunt and Blade Tidwell are all still working back on different timelines, and the Giants intend to keep all four on the 40-man roster even with no clear read yet on how much they might be able to help in 2027.

Giants Bullpen Depth Could Keep Joel Kuhnel In The Picture
Joel Kuhnels run with the Giants was brief but useful enough to keep his name in the mix. Claimed off waivers from the Brewers during the 2026 season, he gave San Francisco 10 appearances and posted a 2.79 ERA, the kind of steady relief work that can matter when a bullpen is being patched together over the course of a long year.
The wrinkle is that Kuhnel is no longer on the 40-man roster, and after going unclaimed on waivers he became a free agent. Even so, the Giants could still circle back on a minor league deal if they want more depth in the relief corps, leaving his future in the organization very much unresolved for now. [Read more 🡒]
