FACTS/FLUKES: Hader, Pederson, Flowers, J. Iglesias, Hellickson

Hader an elite option, regardless of role ... Control issues plagued Josh Hader (LHP, MIL) in the upper levels of the minors when he was a starter, but to say his transition to the pen has been a success would be an understatement. He put up a 2.08 ERA in 35 relief appearances following his call-up in 2017, and then was the most dominant pitcher in the game in 2018, when he whiffed 47 percent of the batters he faced. He now looks poised to record a higher percentage of saves in the Milwaukee pen, so let's check in on these absurd skills.
