I think the season turned with Seattle in town. 9-2 coming out of the AS Game, rare successful west coast road trip completed, one W vs Seattle in the books, up 6-2 on Seattle going into the top of the 8th...and Jovanni Moran happens. Four batters later it's tied. All the good vibes, gone.
Lose that game followed by 4 more in a row and back in the ****.
Almost entirely due to the bullpen, too.
