Let’s look at the closer situations around the Majors. I’m going to be using a color system, “red” means that there is a likely closer change or a very unstable situation; “orange” means that there are warning signs; “green” means that there isn’t likely to be any change at closer.
AL
AL EAST
TEAM: New York Yankees
CLOSER: Aroldis Chapman
STATUS: Green
DETAILS: He’s arguably the best closer in the game. Barring injury he’s safe in his role.
TEAM: Boston Red Sox
CLOSER: Brandon Workman
STATUS: Orange
DETAILS: If not for his xFIP and Matt Barnes and Nathan Eovaldi being better and just having bad luck, I would have put green.
TEAM: Tampa Bay Rays
CLOSER: Emilio Pagan
STATUS: Green
DETAILS: He seems to be running away with the job.
TEAM: Toronto Blue Jays
CLOSER: Ken Giles
STATUS: Orange
DETAILS: Well Giles is easily the closer when healthy, but he’s injured and might miss significant time. He is also a lock to be traded in the offseason. Derek Law might get significant time filling in as their closer this season.
TEAM: Baltimore Orioles
CLOSER: Mychal Givens
STATUS: Orange
DETAILS: He’s not good this season and they replaced him once before, the problem is their bullpen is really weak and he’s still the best overall reliever that they have.
AL CENTRAL
TEAM: Cleveland Indians
CLOSER: Brad Hand
STATUS: Green
DETAILS A very good closer who had the job locked down.
TEAM: Minnesota Twins
CLOSER: Taylor Rogers
STATUS: Orange
DETAILS: He hasn’t been sharp lately, but they don’t have any better options unless they actually go with Sergio Romo.
TEAM: Chicago White Sox
CLOSER: Alex Colome
STATUS: Green
DETAILS: He’s been very good despite shaky peripherals and they seem committed to him in the role.
TEAM: Kansas City Royals
CLOSER: Ian Kennedy
STATUS: Green
DETAILS: He’s set in that role at this point.
TEAM: Detroit Tigers
CLOSER: Joe Jimenez
STATUS: Red
DETAILS: He’s not very good and has no experience as a closer, Buck Farmer is better and might get the job at some point.
AL WEST
TEAM: Houston Astros
CLOSER: Roberto Osuna
STATUS: Green
DETAILS: An elite closer.
TEAM: Oakland Athletics
CLOSER: Liam Hendricks
STATUS: Green
DETAILS: He’s running away with the job at this point.
TEAM: Los Angeles Angels
CLOSER: Hansel Robles
STATUS: Green
DETAILS: He seems to be set in the role at this point.
TEAM: Texas Rangers
CLOSER: Jose LeClerc
STATUS: Green
DETAILS: He has to completely fall apart to lose his job.
NL
NL EAST
TEAM: Atlanta Braves
CLOSER: Luke Jackson or Mark Melancon
STATUS: Red
DETAILS: Whoever pitches best going forward will win what’s turning into a mess of a situation.
TEAM: Philadelphia Phillies
CLOSER: Hector Neris
STATUS: Green
DETAILS: He has to collapse to lose his job and even then there’s no one good enough to get the job.
TEAM: Miami Marlins
CLOSER: Jarlin Garcia
STATUS: Red
DETAILS: Who knows at this point, they might be going with a committee.
TEAM: Washington Nationals
CLOSER: Sean Doolittle
STATUS: Green
DETAILS: He’s set at this point.
TEAM: New York Mets
CLOSER: Edwin Diaz
STATUS: Red
DETAILS: Another poor outing and he will lose it to Seth Lugo.
NL CENTRAL
TEAM: Cincinnati Reds
CLOSER: Raisel Iglesias
STATUS: Orange
DETAILS: He’s not that good, but he doesn’t have much competition.
TEAM: Milwaukee Brewers
CLOSER: Josh Hader

TEAM: Chicago Cubs
CLOSER: Craig Kimbrel
STATUS: Green
DETAILS: He’s set at the job.

DETAILS: He’s set at the job.
TEAM: San Diego Padres
CLOSER: Kirby Yates
STATUS: Green
DETAILS: He’s set at the job.
TEAM: Colorado Rockies
CLOSER: Scott Oberg
STATUS: Orange
DETAILS: If he struggles, they might give it back to Wade Davis due to his contract and track record.
TEAM: Arizona Diamondbacks
CLOSER: Archie Bradley
STATUS: Green
DETAILS: He’s clearly the best reliever in their bullpen.
Interesting extra fact: 17 teams made changed closers this season.
