Sometimes, you just have to look at the guy playing baseball. I'm a saber-minded person who's had a job analyzing the data.
Vogelbach is, visually obviously, not a major league baseball player. Whatever his numbers are in AAA, he will never...not ever...hit for power in the big leagues. Without power, he's a Mike Hargrove level DH. That is...I'd rather have 2007 Jose Vidro than that.
He is the least athletic man I've ever seen at the big league level...his body control is ATROCIOUS. And yes...you have to have some athleticism to hit in the majors or they'll pick you apart by keeping you off your very fragile balance. Which is what they're doing to him right now. He's not just too passive, he's incapable of hitting cripple pitches hard if they are following decent pitches.
I will be personally shocked if he ever turns in a season worth more than 1.5 WAR or so.
