Yeah the Jays depth cascade is just a bit awkward.
A left handed bat who can play CF would fit well. I guess that's Palacios but he can't be relied on much.
Also a left handed infielder who could fall into a platoon with either Smith or Espinal would fit well. This could literally be Biggio if a bona fide starter at 2B or 3B of any handedness is brought in.
Lefties, lefties, lefties. Jays have zero good lefty bats even on the 40 man roster unless you consider Biggio one. Maybe this is why Greg Bird was brought in on the minor league deal.
Might have to be a trade though because you've named all the worthwhile lefties and the list is so short. And they are so flawed, all of them.
