There's a couple of ways to anticipate Angel's impact on Game 2 as the HPU. We can be pretty sure that the strike zone will be something between quizzical and nonsensical. However, if Angel shows up and decides Friday's strike zone begins at the ankles, that could be very good for Keuchel. If, on the other hand, Angel decides that anything below the waist is a ball, that would be a problem.
Then, of course, there's the likely reality of Angel's strike zone moving around like a Niekro knuckleball.
