George Kirby had 20 throws from 60 feet. He will bump up to 75 feet tomorrow. The Mariners have it mapped out with some days off from throwing scheduled. He said the biologics shot in the shoulder definitely helped the process.

Fantasy Impact:

Kirby’s 20 throws at 60 feet Friday, post-biologics injection, advance to 75 feet Saturday, signaling progress from his right shoulder inflammation for the Mariners, with no debut timeline yet. The 27-year-old heals steadily. Fantasy managers in all leagues should stash him, banking on his elite arm for a midseason return to Seattle’s 2025 rotation if his ramp-up continues without hitches.
