If he didn't have defense to work on, when he was raking earlier I would have loved to have seen him called up. If he hit, stay up (give up rookie status), if he struggled get 2023 Cowser treatment and go back down. But the closer we get to the 45 day mark, it makes less and less sense not to wait for it if every other hurdle is crossed.
