I would trade him in a heartbeat if the team and MLB as a whole wasn't so short on catchers who can provide 2.0+ WAR. Fangraphs list Yainer as 1 of only 17 catchers who project to hit that mark, and most of them are not available. The way he gets his WAR is in opposition to how the Astros want the team to operate and perform, but they must have a replacement.
Stros really need him to have an all-around bounce back year. I'm not sure if I was more disappointed with him at the plate or behind it.
The pitching was really good, so I give him credit for behind the plate. Not so much for his bat. He had an off year.
