Ever since the Chicago Cubs World Championship-winning 2016 campaign, the team has enjoyed a handful of guys who have been able to close out baseball games successfully. Aroldis Chapman played a significant role during the postseason that year, followed up by Wade Davis and his 2.30 ERA in 2017, and Brandon Morrow and his 1.47 ERA in 2018.
Unfortunately, last season there lacked a baseline of stability. Craig Kimbrel signed his contract midway through the season, and, while there was significant excitement from fans at first, it quickly fizzled out after his extreme performance and trip to the disabled list in September.
