Just a week ago the Yankees swept the White Sox, who had the best record in the AL coming into the series. They were 23-9 since their lousy start and things were looking up. Since then they were swept by the Tigers and have gone 2-6. So which version of this team is closer to their true form? It's still hard to say. To me the pitching is good enough, even without Kluber (barring an injury to another starter). They'll just have to mix and match every 5th game, maybe have an opener along with Garcia/King. Given that their bullpen is their greatest strength it shouldn't be like every 5th game is an automatic loss.
Defense and baserunning have been lacking, but ultimately the offense is the #1 problem by far. A bad error or getting thrown out at the plate might lose you a game or two, but continuous bad hitting will lose you every game that your pitching isn't excellent. With a third of the season already gone I don't think that we can assume hitters will snap out of it anymore. Cashman needs to make a move for either a CFer or middle infielder (or both). They can't keep running Gardner and Odor out there everyday and expect the offense to hit.
