As the first weekend of 2025 approaches, here are three things we will be keeping an eye on around baseball:

1. Hyeseong Kim’s deadline to sign is fast approaching:

We don’t mean to sound like a broken record, but there’s a good reason why Hyeseong Kim is back at the top of The Opener for a second day in a row. The KBO star was posted last month, and his negotiating window officially opened on December 5, giving him 30 days to sign a contract with an MLB team. He now has less than eight hours remaining before his posting window closes this afternoon at 4:00 PM CT.

MLBTR ranked Kim at no. 26 on our Top 50 Free Agents list this winter, predicting he’d sign a three-year, $24MM deal. However, his name hasn’t come up in many rumors or reports since he was posted. If Kim does not sign today, he will return to his KBO team, the Kiwoom Heroes, for the 2025 season. As Jeeho Yoo of Yonhap News points out, Kim will be an unrestricted free agent next offseason, which means he won’t need to be posted a second time if he wants to pursue an MLB career. That could improve his chances of inking a deal. Not only will he have more time to negotiate, but his new team won’t be forced to pay a release fee to sign him.

2. White Sox 40-man move incoming:

The White Sox have a full 40-man roster, which means they’ll need to make space for Josh Rojas before they can finalize his signing. The free agent infielder reportedly agreed to terms on a one-year contract with Chicago on Thursday, but the team has yet to confirm the news. Financial details of the deal are something else to keep an eye out for this weekend – as of today, they have not been reported.

Earlier this week, the White Sox traded for left-handed Tyler Gilbert and designated infielder Braden Shewmake for assignment to make room on the roster. Thus, their 40-man is currently quite pitching heavy, featuring 24 arms and just 16 position players. With that in mind, it seems more likely the White Sox will cut a pitcher to free up space for Rojas.

3. Owen White’s DFA resolution:

After signing free agent reliever Hoby Milner, the Rangers DFA’d former top prospect Owen White to make room on the 40-man roster. Since then, White has been waiting in limbo. Typically, teams have seven days to resolve a DFA, but that timeline can be extended during the period between Christmas and New Year’s Day. Now that the holiday season is over, however, the Rangers will have to trade White or place him on waivers, presumably before the end of the weekend.
