Interesting that the Jays are either going for one year deals to older players (Estrada extension, Grandy, possibly the fifth starter) or trading for players with many years of pre-FA$ control left (Diaz, Solarte, Grichuk). No in between. They are also stacking up the AAA team with near ready prospects. This seems like the type of set up where the front office is bracing itself for a mid season sell off and don't want to commit to too many older players, while at the same time having cheap fill ins to take over positions in 2019, 2020, etc. They may not even want a free agent starter on a three year deal. Maybe the Morales deal has made them scared.
