It appears the Boston Red Sox once again have their eye on Miami Marlins reliever Brad Ziegler.

The submarine-style pitcher has been the topic of several trade rumors involving the Miami Marlins. Brad Ziegler, who pitched in Boston before in 2016, could be a key addition to the American League East team in its push to the playoffs.

Per Sean Penney of FanSided’s bosoxinjection.com, “FanCred’s Jon Heyman mentioned the Red Sox as a possible landing spot for right-handed reliever.”

It’s a move that would allow the Marlins to receive compensation for a player who will be a free agent at the end of this season.

Ziegler started the 2018 season as the Marlins closer but lost his spot to Kyle Barraclough, who is also the subject of possible trade rumors. He has been effective as a setup man in Miami’s bullpen.

Red Sox still determined to add relief help. Looking into yates, kela, ziegler and many, many others. Have some luxury tax concerns as they are at an MLB high $238M already (not that they haven’t spent well; they have by far baseballs best record) — Jon Heyman (@JonHeyman) July 30, 2018

“He [Ziegler] pitched well for the Red Sox down the stretch, posting a 1.52 ERA over 29 2/3 innings. That’s the type of impact Boston’s bullpen could use now,” Penney added.

The Red Sox are not the only team looking to add relief help and have inquired about Ziegler. The Los Angeles Dodgers are also rumored to be interested if the price is right?

Before manager Don Mattingly moved Ziegler out of the ninth-inning role, he had converted 20 of 26 save opportunities and in his last 28 innings of work, the veteran has only allowed three earned runs.

Kevin Kraczkowski of Marlin Maniac wrote last week that the Dodgers need help in their bullpen as they move toward the playoffs and could call the Marlins to see if a deal could be worked out.

“He’s the perfect candidate for late-season rental-hood,” Kraczkowski writes. “He’s currently signed to a two-year, $16 million deal with the Marlins, but that ends after this season. The Dodgers would be a good fit for him.”

The fact Barraclough is not eligible for free agency until 2022 makes him a less likely candidate to be traded unless a deal comes along the Marlins cannot pass up.

Ziegler is one of four potential relievers in the Marlins bullpen who could be part of deals before the MLB Trade Deadline at 4 PM on Tuesday.
