The A’s have claimed right-hander Domingo Tapia off of waivers from the Royals and optioned him to Triple-A Las Vegas, the team announced. To make room on the 40-man roster, the Athletics designated Mickey McDonald for assignment.
Tapia, 30, has not appeared with the Royals this season. He appeared with the Royals, Mariners, and Red Sox over the past two seasons, however. Tapia owns a career 2.61 ERA over 38 innings between the three teams, notching most of that experience with the Royals last season.
McDonald, 27, has walked twice but failed to notch a base hit in his first six plate appearances. The switch-hitter doesn’t hit for power, but he did put together a .305/.402/.390 line in 430 plate appearances with Double-A and Triple-A last season. He’s likely to pass through waivers and return to the A’s Triple-A affiliate in Las Vegas.
