TORONTO -- Another piece of the Blue Jays' future was added to the 25-man roster on Thursday afternoon with the arrival of left-hander Thomas Pannone.
Pannone was promoted from Triple-A Buffalo prior to Toronto's series finale against the Red Sox, while right-hander Mike Hauschild was optioned to the Minor Leagues. The 24-year-old Pannone is the Blue Jays' No. 28 prospect, according to MLB Pipeline.
The Blue Jays promoted Pannone after he made six starts for the Bisons and posted a 4.91 ERA. The native of Rhode Island missed the start of the Minor League season after he received a suspension for testing positive for a performance-enhancing substance.
Toronto has an opening in its rotation following the departure of Hauschild, who was being used as an emergency replacement. Hauschild allowed four runs over 2 1/3 innings in a 10-5 loss to Boston on Wednesday.
