Defensively, Gimenez is a wizard, and he’s actually having an even better season in the field than he did last year. He’s already up to 2.1 WAR and should probably finish somewhere around 3 WAR. Offensively, if he ends up around .250 with 10–12 HR, 20 SB and an 80–90 wRC+, I can live with that considering everything he gives you defensively. He's a solid player and the Jays could do a lot worse at shortstop.
The bigger issue is that the Jays simply have too many noodle bats in the lineup at the same time: Clement (98 wRC+), Lukes (96), Straw (70), Bateman (83), Kirk (95), Vladdy (97) and Springer (100).
Obviously, Kirk, Vladdy and Springer regressing this badly has hurt them tremendously. But even coming into the season, the Jays were still planning on regularly running out Gimenez, Clement and Lukes. That worked last year because they had Vladdy, Kirk, Springer, Bo and a healthy Barger producing at a high level, along with Varsho when he was healthy.
That’s why the priority this offseason has to be adding as much offense as possible, regardless of where it comes from. If Gimenez and Clement are both going to be everyday players again, you need to compensate for that elsewhere in the lineup and if the plan is also to give Bateman or Straw significant everyday ABs in CF, then yikes. At that point, adding a legitimate bat in LF becomes even more important.
