Free Agent Rumors: Oswalt, Delmon, Sizemore, Ross, Ludwick

Here's the latest from the Winter Meetings on a handful of free agents:

• Roy Oswalt is unsure about whether he'll pitch in 2013, one of his agents tells Morosi.
• The Mariners checked in on Delmon Young, tweets Jon Paul Morosi of FOX Sports.  Morosi reported previously that Young might wait until January to sign given his November ankle surgery.
• Grady Sizemore had been drawing interest from a few clubs, including the Red Sox, but he won't be a real option until midseason, according to MLB.com's Anthony Castrovince.  Agent Joe Urbon confirmed to Castrovince that his client underwent microfracture surgery on his right knee in September.
• Besides being interested in Scott Hairston, the Yankees are also eyeing Cody Ross, according to Jon Morosi of FOX Sports (Twitter link).
• The Mariners have checked in on Ryan Ludwick, among other hitters, tweets Jon Heyman of CBS Sports.
• Cesar Izturis' reps are expected to meet with the Mets this week and there could be a match there, writes Adam Rubin of ESPNNewYork.com.

Earlier updates:

• The Orioles' interest in righty Brett Myers appears minimal, tweets Dan Connolly of the Baltimore Sun, and they have no meetings set up with his reps.
• The Twins are one team with early interest in southpaw John Lannan, tweets Adam Kilgore of the Washington Post.  The Pirates also have an eye on Lannan, reported Rob Biertempfel of the Pittsburgh Tribune-Review earlier today.
• The Cubs are talking to many agents about bullpen help and they like Jason Grilli, tweets Bruce Levine of ESPNChicago.
• Solid interest in Jason Bay (from teams other than Boston) may lead to a Major League deal, tweets Rob Bradford of WEEI.  
• The Marlins are interested in utility man Mark DeRosa, according to Juan C. Rodriguez of the South Florida Sun Sentinel. The 37-year-old had indicated at season's end that he was unsure what his future held.
• The Royals are "sending out signals" that they have the money and the motivation to pursue a pitcher who could be considered a No. 1, reports Danny Knobler of CBS Sports. A run at Anibal Sanchez isn't out of the question for Kansas City, according to Knobler.
• Tigers people continue to say the team isn't even considering Rafael Soriano, tweets Joel Sherman of the New York Post. However, Sherman notes that owner Mike Ilitch's great relationship with Scott Boras still makes Detroit a wild card in the Soriano sweepstakes.
• Rival executives view the Nationals as a good fit for Mike Pelfrey, especially considering GM Mike Rizzo and Scott Boras have a history of working out deals, says Jerry Crasnick of ESPN.com (Twitterlinks).
• Teams are showing "no hesitation whatsoever" in pursuing Jeff Keppinger, who underwent surgery to repair a right fibula fracture, agent Keith Grunewald tells Ken Rosenthal of FOX Sports (Twitterlinks).
• Jason Giambi would like to continue his playing career, and is drawing interest from three or four teams, tweets Jon Heyman of CBS Sports.
