How is Jack Perkins performing?
Jack Perkins has not appeared in a game this season, so evaluation rests on pre-season metrics alone. His 33.61% whiff rate suggests swing-and-miss stuff typical of a relief arm, but without live innings pitched, the profile remains untested. Any projection of strikeout volume or effectiveness is premature until he takes the mound.
