Over the course of just two seasons, Treinen, a now-31-year-old righty sinkerballer, went from being arguably the best reliever in all of baseball to being removed from the closing role by the Oakland Athletics during the regular season and being non-tendered this offseason by the team that drafted him back in 2011, before being signed by the Dodgers. The lanky 6’5” power pitcher mixed his sinker, fastball, changeup, and slider almost perfectly two seasons ago, solidifying the A’s bullpen on his way to his first career selection to the All-Star team. A seventh-round pick out of South Dakota State, a school that only went Division I the year he signed with them, Treinen needed less than 50 games in Single-A before being elevated into the MLB.
