The New York Yankees
The Yankees have one of the best bullpens in baseball so, on paper, you might think that they don’t need bullpen help but they have suffered a lot of injuries in their bullpen recently.
Miguel Castro (the Miguel Castro that the Rockies got in the Troy Tulowitzki trade) is on the IL with a shoulder injury. He won’t even throw a baseball for another two weeks, let alone be pitching in the majors. Setup man Michael King also is done for the year with an elbow injury. Former closer Aroldis Chapman has also been awful on the season (5.48 ERA, 5.61 FIP).
The Chicago White Sox
The White Sox are another team on the periphery of the playoff picture as they are also at .500 and 3.5 games back of the final AL Wild Card spot.
The White Sox have a good closer in Liam Hendriks (who was an All-Star) but their bullpen still has an ERA of 4.07, or 21st in baseball. One of their setup men (Reynaldo Lopez) is also on the 15-day IL. He has been great for them as he has a 2.98 ERA in 37 appearances.
