Seabold was recalled from Triple-A Worcester ahead of Monday's game against the Blue Jays.
EDGE Analysis
The 26-year-old will make his season debut as Monday's starter in Toronto after Kutter Crawford was sent down Sunday. Seabold has made 11 starts in Worcester this year and has posted a 2.09 ERA and 1.00 WHIP in 51.2 innings. Whether he makes another return through the rotation following Monday's start likely depends on when Garrett Whitlock (hip) and Nathan Eovaldi (back) are cleared to return.
