Jesus Montero is fat.

 Pineda was traded for Montero, as we all know.

Therefore, Jon Heyman feels compelled to bring up Montero ... and mention the word "neck":

"Maybe they are guilty of not knowing how crazy he is about this stuff, of not knowing that on the maturity scale he's in a neck-and-neck (sorry) battle for the basement with even Jesus Montero, the young man with the sinking career he was traded for two years ago, the young man who admitted upon arriving in Seattle's camp this spring that the reason he looked like he weighed 270 pounds and resembled a blimp is that he couldn't stop himself from eating everything in sight.

Montero is buried in the minors for struggling Seattle, so in terms of baseball value the Yankees stand far ahead in the trade of child-like savants. They are quite a pair indeed, a couple addicts in their own way (Montero for food and Pineda pine tar). But in the race for maturity, by owning up to his sins even Montero may be a neck in front."
