Mason Miller made his MLB debut on 04-19-23, striking out the side in order in his first big league appearance. The 6-6, 240-pound right-hander from the A's bullpen worked a perfect eighth inning, punching out Yordan Alvarez, Alex Bregman and Jose Altuve in succession. Miller's blazing fastball and wipeout slider had Texas' potent lineup frozen throughout his memorable debut.
