This winter will be a tumultuous one for the Yankees, with a lot of new faces expected to be brought in and old ones expected to depart. To keep up with it all, we will track each of the players the Yankees are trying to keep or pursue in a feature we call "Market Watch."

Before every game, Joe Girardi makes a list of his available relievers, beginning with his closer and working his way down. Next year, the top of his card will read David Robertson instead of Mariano Rivera. After that? Well, at this point, it is anyone's guess.

The eighth-inning job, left-handed specialist and basically every other spot is open. Boone Logan is a free agent, but may not fit in the $189 million picture. Joba Chamberlain's Yankees career is over. Shawn Kelley, Preston Claiborne, David Phelps, Cesar Cabral, Adam Warren and Dellin Betances could all be in the mix.

So the Yankees will have their eyes open for anyone who could help in the pen. The New York Post reports that could include 31-year-old Korean righty Oh Seung-Hwan.

According to reports, Oh’s fastball is between 94 and 96 mph and he has a splitter that disappears. The 5-foot-10, 208-pound right-hander was 4-1 with a 1.74 ERA and saved 28 games.

Like Masahiro Tanaka, Seung-Hwan is scheduled to be posted in November.
