Pirates option Daniel McCutchen to Triple-A
The Pirates announced the move Wednesday.
Pittsburgh is the third team this season for Qualls, who began the year with Philadelphia and was acquired in a trade with the New York Yankees on Tuesday. He is 2-1 with a 4.89 ERA this season.
McCutchen, who was recalled Tuesday, has not pitched in the majors this season after making 73 appearances with the Pirates a year ago.
