A simplified delivery and a stolen slider could push Dan Altavilla into the Mariners opening day bullpen

PEORIA, Ariz. — If a pitcher — reliever or starter — struggles and puts up poor results in the Cactus League, there’s often one of a variety of reasons listed as the cause behind it.

Some examples being:

  • Working on a certain pitch
  • Experimenting with a mechanical adjustment
  • The dry air of Arizona affecting breaking pitches
  • Just trying to build the pitch count and not show too much to hitters.

Within reason, all of these are somewhat acceptable and logical causes of a statistically bad outing.
