New A's Pitcher From Houston Astros Made One Big Change in Debut

On Thursday Brandon Bielak was traded from the Houston Astros to the Oakland A's. A few hours later, the 'Stros completed their four-game sweep of Oakland. On Friday, Bielak was officially added to the A's 26-man roster, with the team optioning left-hander Hogan Harris back to Triple-A. With the A's struggling to get innings from their pitching staff of late, having fresh arms to get through each game has resulted in a revolving door between the big leagues and the minors for the past week.
