"Maybe Lucroy’s issues are purely mechanical or mental, the product of bad habits or frustration about his slow start at the plate. But it’s probable that age and injuries have taken their toll. Lucroy suffered a fractured finger in 2011; a fractured hand in 2012; hamstring soreness in 2014 and 2015; a fractured toe in early 2015; and a concussion in late 2015. Maybe that accumulated wear and tear has made him less low, less mobile, and less steady behind the plate.
The bad news for Lucroy — and, for the rest of this season, the Rangers — is that large changes in framing performance tend to be sticky; it’s rare for a catcher to suffer a significant decline as a receiver and then bounce all the way back. In other words, the elite Lucroy, and even the average Lucroy, may be gone for good. "
The good defensive Lucroy is history pal.
