Bad or questionable calls are magnified when teams are losing. If the Sox were on a six game sinning streak, you'd have forgotten about any bad calls, especially ones like yesterday that had no bearing on the outcome.
When you are struggling, every call, every at bat, every blown save, everything is magnified.
Yeah and also i think its got to do with karma. I mean when you dont put out much effort, the breaks are going to go against ya.
