Cubs OF Pete Crow-Armstrong looked like a difference-maker on defense in his debut. I’ve read some speculation that he wouldn’t be a lineup regular over the next few weeks, and I have to disagree with that. Granted, teams don’t always do the things that make sense with their prospects, but PCA is a playoff weapon, and so long as he doesn’t strike out too much (29.7 percent in Triple-A), he’ll make the team better by covering center.
