8:15pm: Oswalt's agent Bob Garber says he's unaware of any interest the Mets may have in his client for the 2013 season, writes Marc Carig of Newsday.

1:32pm: The Mets are interested in free-agent right-hander Roy Oswalt, and the door has not fully closed even with the addition of Shaun Marcum, a baseball source told Adam Rubin of ESPNNewYork.com. It was reported earlier this month that Oswalt was on the fence about pitching in 2013 and many teams had given up on trying to lure him back, sensing that he would choose to call it a career.

Oswalt hooked on with the Rangers on a minor league deal last summer and posted a 5.80 ERA with 9.0 K/9 and 1.7 BB/9 in nine starts and eight relief appearances. The 35-year-old has dealt with his fair share of injuries over the last couple of years with issues ranging from lower back inflammation in 2011 to a forearm strain at the end of last season.
