The Mets have shown interest in free-agent right-hander Roy Oswalt, and the door has not fully closed even with the addition of Shaun Marcum to round out the projected rotation, a baseball source told ESPNNewYork.com.
Oswalt, 35, went 4-3 with a 5.80 ERA in 17 appearances (nine starts) in 2012 with the Texas Rangers. He made his season debut June 22 -- less than four weeks after signing with the club on a minor league deal.
Oswalt worked entirely in relief last September. He made only 23 starts in 2011 because of lower-back inflammation.
