And he started to do so this call-up, having finally been given a reasonable chance with some starts against non-elite starting pitching, and making some good contact for outs in addition to his overall line.
Certainly, that June batting line isn't setting the world on fire, but let's be honest. His role on the 2015 team was always going to riding the AAA shuttle. Even a .300/.400/.500 line over almost a week's worth of plate appearances would have meant packing up his locker to make room for Victorino.
Whether that's fair or what's best for any party involved, whatever. But you can't reasonably consider two separate call-ups, the first of 13 PA and the second of 22 PA, to count as "having an opportunity to succeed." That's simply disingenuous. JBJ had an opportunity to succeed last season, and fell flat on his face with one of the worst batting lines I've ever witnessed. That being said, he has never been given any opportunity to succeed this season, after he changed his swing back to the one that made him a top prospect in the first place.
