Pinch Hitting

Why does Ty France continuously pinch hit for Charlie Blackmon when Blackmon is set for do not pinch hit for both LHP and RHP and France is not even my designated pinch hitter vs LHP? It seems to happen mid game so I lose one of my middle lineup hitters constantly and end up Ty France vs a RHP Closer at the end of the game.

Sounds like you accidentally set France as Blackmon's "platoon PH" partner in the lineups tab.
