So, two of our posters above commented on Sheets' swing. I thought it was a bit loopy also, but then I thought it must have always been that way, because his minor league stats were not overwhelming. I thought then that he probably worked hard to improve it. Of course, I say this without ever seeing him play before this year.
Speaking of long, loopy swings, the extreme here is the Dodgers' Cody Bellinger.
