5 options the Chicago Cubs have for the closer role in the bullpen

4. Jeremiah Estrada

One of the guys with the highest ceilings in the entire Cubs system is right-hander Jeremiah Estrada. With a blazing fastball in the upper 90s and a slider that ranks among the best on the team, Estrada is projected to be a long-term bullpen weapon. So far this season, Estrada has been called up twice and been utilized just four times. He has yet to surrender a run in 5.1 innings and has collected 9 strikeouts. For the Iowa Cubs this year, Estrada has also dealt at a high level with a 0.96 ERA in 9.1 innings. I don't think the 24-year-old has been given the opportunity to showcase his full potential yet and he needs to get some more high-leverage looks with others struggling.
