Let’s take a look at the closing situations around the Majors. Generally speaking trades for closers are hard, as they’re typically overpriced, so I don’t recommend them unless you find a reasonable owner.
NYY: Clay Holmes has the job locked up. Nothing to see here folks.
TBR: It’s a committee.
BAL: As long as they’re winning, Jorge López isn’t losing his job. If they fall out of the playoff race he still is likely to keep his job.
TOR: Jordan Romano is keeping his job.
CWS: Liam Hendriks is safe.
CLE: Emmanuel Clase received an extension prior to the season, so he’s not going anywhere.
MIN: I expect them to acquire a closer, so this maybe a good time to trade Jhoan Durán.
HOU: Ryan Pressly is pretty safe.
LAA: Raisel Iglesias signed a massive extension last off-season, he’s not going anywhere.
TEX: They have a committee.
OAK: Dany Jiménez is unlikely to be traded as he’s coming off of an injury and isn’t a free agent any time soon.
MIA: Tanner Scott is one of the few productive relievers in their bullpen, and isn’t a free agent for two years. He’s unlikely to be traded when he’s not a free agent for a couple years. Keep an eye on Anthony Bender as a potential replacement though.
PHI: Seranthony Dominguez is doing a great job and isn’t a free agent for a couple years. The pitching-needy Philadelphia with an eye on contention next year won’t trade him. Former closer Corey Knebel will be moved if they drop out of contention though.
ATL: Kenley Jansen isn’t going anywhere, but there’s an outside chance that they’ll look for an upgrade.
WAS: There’s a chance that Kyle Finnegan is moved, and if he is then he’s no longer going to be a closer and they will have a committee.
NYM: Edwin Díaz isn’t going anywhere and isn’t losing his job.
STL: Ryan Helsley has the job locked down, but they can always upgrade.
LAD: Craig Kimbrel has a -0.2 WAR with a 4.09 ERA, but a 1.96 FIP. They will look for bullpen help, but Kimbrel might be safe.
SDP: Taylor Rogers has been shaky, but they may stick with him.
ARI: Mark Melancon isn’t closing anywhere else and might not even be traded, as he’s not a free agent until after next season.
COL: The smart thing to do is to trade Daniel Bard, but it’s the Colorado Rockies. In the rare case of them making a smart transaction, he won’t be a closer on a new team and they‘ll have a committee.
SFG: Camilo Doval is safe, but they may look for an upgrade.
