The Pirates have had no shortage of breakout prospects over the last few years. This comes from their approach of drafting and signing toolsy players who are raw, but have a lot of upside. After signing so many of those players each year, a few are bound to break out. We've seen this take place almost every year recently, from the big breakouts like Gregory Polanco and Tyler Glasnow, to the smaller scale breakouts like JaCoby Jones or Elias Diaz.
The term "breakout" can be very subjective, as there are different levels of breakout performances. Steven Brault could be considered a breakout guy this year.
