I don't know how many times I've written that Boone Logan's future with this club relies largely on his ability to develop that (hopefully large) muscle between his ears, with good reason. Logan has major league stuff; featuring a riding 91-93 MPH fastball, funky delivery, and a sweeping breaker. Don Cooper agrees, saying, "with the physical stuff [Logan] possesses, he can be one of the top lefties in the American League," before finishing with a signature Cooper colloquialism about Kewpie dolls at carnivals. Those physical tools can only take you so far, however, as Logan demonstrated when he melted down with a series of errors in a single inning in May and the inability to find the strike zone with any reliability at the major league level.
The kid wasn't ready to deal with everything that goes along with being in the big leagues. Logan addressed that himself in quotes provided by the Sun-Times' Joe Cowley.
I'm still unsure if Logan has the mental fortitude to succeed at the majors in high pressure situations, but I feel better about his chances than I did before reading this article.
