Ruiz is still fairly young and was a top 30 prospect. I think a new hitting coach could unlock his potential and make him more of at least an average bat. He can make contact, but he doesn’t draw walks and doesn’t hit the ball hard consistently. I think he could work to increase his bat speed, patiently wait more for pitches he can do damage with, and sacrifice striking out a little more. A 250/300/450 slash is a reasonable goal. He still will be bad defensively, but with automation of balls and strikes, pitch framing at least won’t matter.
I think ultimately we likely need a solid catcher to pair with Ruiz versus him being the bell cow. A Gomes/Suzuki split is what I’d expect. Perhaps the other catcher can be stronger defensively to play in matchups against teams that run a lot.
