35 times this season the Astros have lost a game in which they were either tied or ahead in the score at some point from the start of the 6th inning on. I don't have the exact number, but there were at least a half dozen more games in which we were at some point down by only 1 run from the 6th inning on. That doesn't bode well for the playoffs. On a silver lining note, we have not been competitive in about only 20 games this season.
Absolutely. In the playoffs the Astros only need to have the lead when the game is over 11 times. It's a lot easier to do this 11 times than 92.
