We won 7 in a row against mostly lousy teams. We lost 2 in a row to a team that, along with the Rays, Jays, Astros, and White Sox, are the pool of teams with pitching good enough to get to the ALCS.
The Sox hitting is pretty good, but the Yankees pitching nevertheless cut them down to size. The Yankees hitting, on the other hand, hammered our ace in game 1, were in turn cut down to size by Pivetta, and then hammered our bullpen, all of whom (except Brasier, who pitched a meaningless 9th) showed their asses: Robles with his first pitch wild pitch that brought in the Yankees first run, Houck with his obvious stage fright and abysmal four walks, and Hernandez, also scared to death in a big game, with his walk/HBP, followed by a fast ball down the middle to the Yankees hottest hitter for a grand slam.
The Sox, as you imply, can still get to the wild card because they have a favorable schedule. But even most loyal of Sox fans must recognize that this year the pitching just isn't there and the actually pretty good Sox hitting is no match for good pitching.
