The biggest return at the MLB trade deadline for the Pirates was Rafael Flores, and his start in Triple-A has been rather disappointing. He's posted a 63 wRC+ through 24 games. He has a ton of time to figure it out, but all of his success in the Yankees' organization will be history as he has already come out and revealed the differences in player development.
Colin Beazley of the Pittsburgh Post Gazette interviewed Flores, and what Beazley was able to come away with is somewhat concerning.
"He’ll also have to adapt to a new organization," Beazley wrote.
