Giles signed a minor-league contract with Atlanta on Friday that includes an invitation to spring training.
Giles held a showcase for teams last month and came out of it with a deal from Atlanta. The veteran reliever allowed 19 earned runs in 18 innings last season at Triple-A Oklahoma City and made just nine total appearances in the majors from 2020-22 due to injury. Still, the 33-year-old righty has 115 career saves and a 12.3 K/9 over 362 big-league relief appearances, and he carries little risk as a non-roster invitee.
