He made his Major League debut with the Astros in 2011. Carpenter spent the first half of 2012 with the Astros before being traded to the Toronto Blue Jays, he ended the season in the Toronto bullpen. In 2013, Carpenter was the set up man for the Atlanta Braves and posted an ERA under 2.00. Carpenter was traded to the New York Yankees before the start of the 2015 season and again to the Washington Nationals midway though the season.
