The Chicago Cubs have rebounded from early-season bullpen struggles to boast one of the most effective relief corps in baseball. After starting the season with a 5.23 ERA and facing significant meltdowns, the Cubs have transformed their bullpen, now leading the majors with a 2.70 ERA since mid-April. Key contributors like Ryan Pressly, despite early setbacks, have found their groove, while manager Craig Counsell's adept mixing of pitchers has been crucial. The notable rise of Daniel Palencia as a closer adds depth to an already impressive lineup.

This impressive turnaround has kept the Cubs firmly atop the NL Central, with a favorable odds of -220 to clinch the division. Much of their success can be attributed to the manager's strategy in utilizing a diverse set of pitchers, reminiscent of the “Island of Misfit Toys” from Billy Beane's era. With the season progressing, the Cubs are looking to maintain momentum and solidify their status as playoff contenders.
