Right-hander Sean Hjelle was optioned to Triple-A Sacramento, clearing space for a new addition from the farm system. That spot will now be filled by Carson Seymour, who is set to make his Major League debut.
Seymour, 26, is ranked as the Giants' No. 20 prospect by MLB Pipeline. The Southern California native was quietly scratched from a scheduled Triple-A start on Thursday, a late change that foreshadowed his call-up.

Seymour has posted a 3.89 ERA over 74 innings in 15 starts for the River Cats this season. He was acquired by the Giants as part of the Darin Ruf trade with the New York Mets in 2022. While he has worked primarily as a starter in the minors, he's expected to contribute out of the bullpen for San Francisco.

The Giants' relief corps leads MLB in several key metrics this year but has struggled lately, allowing at least one run in six straight games and posting a 5.84 ERA over that span.
Hjelle gave up four runs in one inning during his last appearance against the Miami Marlins on Thursday. He has a 6.75 ERA over nine outings this season.
