Nov. 5: After going unsigned until June, Craig Kimbrel struggled to find a rhythm in 2019, making multiple trips to the injured list and finishing with a 6.53 ERA in 23 games. However, he should remain Chicago's closer entering 2020.
Nov. 5: Archie Bradley could get a chance to be the D-backs' unquestioned closer entering 2020. The right-hander went 18-for-19 in save chances and had a 2.10 ERA over his final 25 appearances in 2019.

Nov. 5: Brad Hand dealt with a tired arm in the second half and posted a 5.68 ERA with four blown saves over his final 20 appearances in 2019. But if he's healthy to begin 2020, he will likely be the Indians' closer.
Nov. 5: After returning from the injured list in September, Sean Doolittle split closer duties with Daniel Hudson down the stretch and during the Nationals' run to a World Series title. But with Hudson now a free agent, Doolittle could regain the job in 2020.
