This is why Joe Kelly should be the Boston Red Sox set up man.

#Joe Kelly hasn't allowed a run since April.

"He's working on a streak of 16 straight scoreless appearances and boasts a 1.27 ERA with 21 strikeouts in 28 1/3 total innings this season out of the Red Sox bullpen. Kelly has averaged 98.7 mph on his fastball in 2017, among the highest marks in the majors. He averaged 96.3 mph with his heater in 2016."
