Outfielder Everson Pereira has been with the Yankees for a while. He signed for them in the July international free agent period (it’s now in January) of 2017, yet he is still 22. The team has been patient with him, and he has developed slowly (mostly because of injuries), but steadily.
He has now mastered Double-A. That process started last year, when he hit .283/.341/.504 in 123 plate appearances (128 wRC+), and continued this season with his .291/.362/.545 line and 143 wRC+ in 185 trips to the plate before going to the injured list in late May with was described by Mike Ashmore as a lower body injury.
