While it remains possible that Corey Kluber will be traded, a deal becomes less likely by the day, according to sources.

Kluber will soon report to his ninth Spring Training with the Cleveland Indians.

The Milwaukee Brewers, Los Angeles Dodgers and San Diego Padres have all been linked to the right-hander.

The Detroit Tigers haven't found a trade partner for Nicholas Castellanos and are unlikely to deal him until midseason.

His agent recently said Castellanos would prefer to be traded sooner rather than later.

"He wants to win and understands the direction of the franchise right now is to procure prospects," Castellanos' agent, David Meter, said. "That being said, he would rather start with his new club going into spring training."

Nicholas Castellanos will be a free agent after the season and has made it clear to the Detroit Tigers that if he's traded he wants it to happen before Spring Training.

"He wants to win and understands the direction of the franchise right now is to procure prospects," said David Meter, Castellanos' agent. "That being said, he would rather start with his new club going into Spring Training."

Recently, Al Avila said the trade market for Castellanos has "been very frustrating."

The 26-year-old is due to make $9.95 million in 2019.

The Atlanta Braves will "definitely" be involved in trade talks as the offseason progresses.

The Braves pursued James Paxton and Edwin Diaz before they were dealt to the New York Yankees and New York Mets, respectively.

"We're definitely going to be involved in trades," Alex Anthopoulos said. "At the end of the day, we really feel strongly about the talent we have. We've put some good young players on the table in [proposed] deals.

"Whether it was Trade Deadline last year or even this offseason, we've been pretty engaged on the trade market," he continued. "But we haven't been able to say 'yes' to a deal we thought made sense for us. We have the players to go get [big names]. We certainly have the currency. We have the prospects to do it. It's not a financial thing. It's ultimately when we're making a decision from a baseball standpoint, do we think this is the right move for the organization?"

The Miami Marlins remain in discussions with the Los Angeles Dodgers regarding J.T. Realmuto, according to multiple sources.

The two clubs have had on-and-off dialogue for most of the offseason.

The Houston Astros, Atlanta Braves, San Diego Padres, Tampa Bay Rays and Cincinnati Reds are also in the mix for Realmuto.

The Los Angeles Dodgers are looking for some right-handed hitting and have had "ongoing and active discussions" with the Pittsburgh Pirates about Starling Marte, according to a report.

Marte is under contract through 2021.

Even after trading Yasiel Puig and Matt Kemp to the Cincinnati Reds, the Dodgers have a surplus of outfielders.

Marte carries a base salary of $10 million this coming season.

The Cincinnati Reds and New York Yankees are nearing a trade centered around Sonny Gray, according to multiple reports.

The Yankees would reportedly get a draft pick and infield prospect Shed Long in the deal.

Cincinnati is working on a contract extension with Gray.

Gray avoided arbitration by agreeing to a one-year, $7.5 million contract with the Yankees last week. He will be eligible for free agency after the 2019 season.

The Chicago Cubs are facing a budget-crunch and have considered the idea of trading Ben Zobrist, according to a report.

Zobrist carries a $12.5 million salary for 2019 and the Cubs are looking for bullpen help.

The New York Yankees appear focused on trading Sonny Gray.

The shift in focus comes after reaching an agreement on a three-year deal with Adam Ottavino.

The Cincinnati Reds, San Francisco Giants, Milwaukee Brewers, Oakland A's, San Diego Padres, Atlanta Braves and Seattle Mariners have been linked to Gray.

Wil Myers said Saturday that he's moving back to the rebuilding Padres' crowded outfield, indicating that San Diego is likely still in the market for a third baseman.

Myers said the decision to switch positions yet again was made during a recent discussion with general manager A.J. Preller and manager Andy Green.
