Giants sent RHP Gregory Santos outright to Triple-A Sacramento.
Santos was passed through waivers to free up a spot on San Francisco’s 40-man roster to claim reliever Eric Cerantola off waivers from the Royals. The 26-year-old made three appearances for the Giants earlier this year. He was an interesting high-leverage option a couple years ago, but is merely extra organizational depth at the juncture of his career.
