Thanks, Brad Penny. But it may be time to move on.
Luck hasn't been on his side, I will give him that. Penny has had to deal with a .326 BABIP, while surrendering line drives on only 18 percent of batted balls against. And his LOB percentage is at 66, which is far too low. Eventually, he should strand a few more base-runners.
But it is his love with the fastball, and the home run that is killing him. Do you know how often Penny throws the fastball? 73 percent of the time! This is the American League East, Brad. There has to be somewhat of a reliance on the breaking stuff too. Maybe he doesn't feel comfortable throwing it. And he doesn't always seem to have command of it. But his curveball has a "Pitch Type Value" of -15.4. That is horrendous.
Point is, he has no viable pitch outside of the fastball, and at times he even struggles with that. That is why he is so reliant on it. he simply cannot do anything positive with the breaking ball.
