The Toronto Blue Jays have had very little success under General Manager Ross Atkins in developing starting pitching. Whether it's been guys who haven't lived up to their potential, such as Nate Pearson, or players who have showcased flashes of brilliance before getting hurt, such as Alek Manoah, the Blue Jays pitching rotation has survived mostly thanks to the trade and free agent routes.
In fact, the Blue Jays have had just two home grown players start a playoff game for them in the last ten years. Marcus Stroman got the ball in Game Three of the 2016 ALCS against the Cleveland Guardians, and Manoah was the Game One starter in the Blue Jays 4-0 loss to Seattle in the 2022 Wild Card series.
