Martin Maldonado is expected to be the first string catcher again in 2023. But the the emergence of not one--but two--catching prospects mean there is competition for the 2024 season.
I would be rather surprised if either Lee or Diaz is the Astros primary catcher in 2024 and beyond. Lee is widely viewed as nothing more than average defensively (although he has a cannon for an arm). Diaz can flat out rake, but can generously be described as mediocre behind the plate. The lineup can carry Machete’s paltry offensive output. And as you said, his (immense) value to the Astros is in his other skills. I have to think that 2023 is his last year starting full time and the Astros are actively looking for his replacement outside the organization.
