Doesn't matter what pitch you throw or where you throw it. All hitters against you have an expert eye and won't chase anything out of the strike zone. Played two games back to back. One game I did exactly what the catcher called. The other game all fastballs down the middle. Gave up one run in 6 innings throwing the fastballs, 2 runs in 7 innings doing what the catcher called.. And had 2 strikeouts in each game.
