Prospects TLDR: Martinez is a wild stallion pitching prospect with upper-90s arm strength and plus raw breaking ball quality. Though he has prototypical starter size and physicality, he's struggled to throw strikes and produce good results in the lower minors. His 40-man timeline gives the Pirates through mid-2027 to help Jeter make strike-throwing progress before it might be prudent to put him in the bullpen. If left to air it out an inning at a time, he could be a late-inning weapon.
