The Pirates have some shopping to do once the off-season really gets under way (and that might not be for another month). They need pitching, mostly starting pitching, but also possibly a late inning reliever to add to their current mix of Tony Watson, Felipe Rivero, and Juan Nicasio.
They have a lot of pitching prospects in the upper levels right now. We started to see some of them arrive in 2016, with Jameson Taillon and Chad Kuhl making the biggest impacts. Guys like Steven Brault, Trevor Williams, and Tyler Glasnow also arrived for brief appearances. All three of those guys should provide starting depth in 2017, with the hope that Glasnow figures it out, and with the option for Brault and/or Williams to transition to the bullpen, if needed.
