This comment sounds like it’s coming from someone who doesn’t know the Jon Singleton story. There’s little doubt Yordan will be up in 2019, I don’t think anyone will argue that. But it won’t be before Super 2.
FYI, Grichuk is out of options and can’t be sent to AAA without clearing waivers. That said, I think the Jays will make room somehow for Teoscar if he keeps hitting, even if it means releasing Grichuk.
