I've read some social media posts making comments about Valencia's defense being subpar during spring training games.
Here's a scouting report from Bless You Boys:
From the article: Behind the plate, Valencia still lacks the framing, blocking, and pop times to play the position regularly at the major league level. He stands 6’1” but he’s quite stocky at this point, with below average speed and agility, which doesn’t bode
real well for his ability to improve behind the dish. Gabe Alvarez, his manager in Toledo, preached some patience considering the injury history and lack of reps, and that carries some weight, but we’ll just have to see how he’s improved this spring after
an offseason in which defense was a major focus for him.
On a club that highly values catchers for their defensive ability, it’s hard to imagine Valencia getting much catching work without some real improvements. He’s clearly put a ton of work into it already, and so the odds of a major transformation at age 26 are
slim.
The Tigers place strong emphasis on defense from their catchers so Valencia seems to be 4th or even 5th on the depth chart because his defense isn't major league level. He could be the best hitter of the Tigers' catching options, but
right now he's behind Tomas Nido because Nido is much more polished defensively (apparently Nido has been working with Valencia on his catching skills). I'm not saying I agree with putting Valencia behind Nido (or even Jake Rogers) in the depth chart, but
that's what the Tigers are doing because they don't think Valencia's defense is ready for the majors.
The good news is that Valencia gets good reviews of his hitting skills (plus he lost some weight going into camp this spring). He made huge improvements last year and has some legit hitting skills. If Tork gets injured or struggles badly, Valencia might be
a 1B/DH option.
