Allow the hitter only one foul ball after strike two. After that a foul ball counts as a strikeout. Batter can’t call time during an at bat, has to be back in the box five or so seconds after the previous pitch. No conferences between pitchers and infielders or even the catcher when they’re in the field - talk strategy in the dugout during the half inning you’re at bat.
Surprising, but by my count games played since the trade are Gagner 101 AA 75 so that explains a bit. AA was hurt and has only played 19 games this season.
