Garcia signed a minor-league contract with the Athletics on Nov. 14.
Garcia is expected to open the 2023 campaign at Triple-A Las Vegas, though he'll likely get the opportunity to attend Oakland's big-league camp this spring as a non-roster invitee. He made six appearances out of the Baltimore bullpen in 2022 but otherwise spent the majority of the season at Triple-A Norfolk, where he produced a 2.34 ERA and 1.14 WHIP in 34.2 innings.
