Few prospects ever had the hype of Vladimir Guerrero Jr. And those plaudits were well-earned. No one — since FanGraphs started tracking the data — had a rate of homers to strikeouts at age 19 at Double-A or higher approaching Guerrero’s, a list that includes Mike Trout. And that was while hitting .381 with a .437 on-base percentage.



But in the majors, Guerrero just can’t seem to get on track.



After a horribly slow start seemingly driven by being pitched to “like a feared slugger while also getting the rookie treatment from umps,” Guerrero seemed to find his stride with a titanic homer against the Yankees on June 5. After that game, his average was .256 with an isolated slugging (slugging average minus batting average) of .216. His on-base plus slugging stood at .798.



But that’s been his only homer in the entire month of June. On Sunday, he went 0-for-5 with two Ks and his slash line fell to .246/.315/.410.
