The Blue Jays acquired Seabold from the Tigers on Wednesday in exchange for Juanmi Vasquez.
Seabold had been designated for assignment by Detroit and is now headed to a new organization. He was with the Blue Jays during spring training but was a late roster cut before linking up with Detroit. The 30-year-old held a 3.45 ERA and 14:5 K:BB over 15.2 innings out of the Tigers' bullpen and will give the Blue Jays some additional length in their relief corps.
