Bailey signed a minor-league contract with the Athletics on Tuesday.
Bailey was let go by Minnesota in September of 2020, and he'll report to Triple-A Las Vegas going forward. The right-hander didn't appear with a team during spring training, but he made the roster for Team USA during the Olympic qualifying tournament. The 35-year-old has made 33 major-league starts across the last two seasons, and he posted a 4.52 ERA and 1.31 WHIP in 171.1 innings during that time.
