Brian Cashman's Deadline Blunders Just Handed the AL to the Astros

New York Yankees GM Brian Cashman has done an excellent job building a contender this season, but that doesn't mean that he's beyond reproach.

Cashman had a lot on his plate this trade deadline, as he needed to improve the Yankees' poor starting rotation in order to tread water in the AL pennant race. Not only did Cashman fail to make a trade to bolster the rotation, but he let arguably his biggest obstacle to a pennant add the biggest name on the market now that Zack Greinke is a Houston Astro.

With a four-man playoff rotation of Greinke, Justin Verlander, Gerrit Cole, and the surprising Wade Miley, the AL is officially Houston's to lose.

Even if Greinke had New York on his no-trade list, other pitchers were right there for the taking, but the Yankees proved too stingy to act. Due to that wavering, Marcus Stroman is a Met and Trevor Bauer is a Red.

Hoarding prospects is one thing, but Cashman's apparent reluctance to jettison even one or two of them in the hopes of building a World Series contender is baffling. In doing so, he's allowed the Astros to leapfrog his Yankees as AL favorites.
