Looking at the standings it isn't that difficult for the Jays to make the playoffs. There are three WC that will make it and those are three of Yankees, Orioles, Jays, and Rangers/Astros.
No AC Central team will make it, Angles and Mariners are out and the Red Sox are out as well I would think.
If Ryu or Manoah comes back, and is a decent middle-of-the-rotation, starter then the rotation is set. They also have depth with one of Manoah or Ryu or they can go with a 6 man rotation in the best-case scenario.
Chad Green will improve the bullpen and they could use another arm.
Jays definitely need a right-handed bat that mashes righties something they didn't get in the off-season.
