Wow - now that's an interesting one. Peters is under control until 2032 and appears to be legit defensively in CF.
He's 26, so you get his prime years, but his minor league numbers suggest the bat isn't this good (perhaps not nearly this good), so there's risk there. Oddly enough, you could say the same thing about Valenzuela - they are very similar that way - the body of work, with this success offensively is very small.
The underlying numbers from Peters don't really move the needle - and likely suggest he isn't a 120 wRC+ hitter. But could he be a 105 wRC+ hitter? He'd still be valuable at that.
I actually like it. Trade from a position of strength with a probability that you're selling high on what likely amounts to a very good backup catcher (which he was always expected to be). It's a tough pill to swallow - I love what BV has brought and think there's a decent chance he can start at the ML level - but CF is going to be a really hard position to fill, with very few options. This would plug a big hole and allow us to spend FA money on positions with more depth and options. Kirk is our man behind the dish anyway and we just added 2 new catching prospects within the system.
To be honest - this is a great option for the Jays. We can include Varsho for a lottery ticket too if the Sox want to fill the hole Peters leaves - make it a bigger trade...
Unfortunately, the White Sox have Teel and Romo, who are both young, highly talented catchers, so I doubt this happens - but I think you're onto something. Trading BV for a young, controllable CFer should be explored.
