The Yankees have expressed interest in Nationals lefty reliever Sean Burnett, though the two clubs have not yet had any discussions according to MLB.com's Bill Ladson (Twitter links). Craig Heist of WTOP 103.5 FM in Washington originally reported the rumor. Ken Rosenthal of FOX Sports says that the Yankees have discussed Burnett internally, but Washington has not yet made him available (on Twitter).
New York has been looking for left-handed bullpen help basically all season, since they learned that free agent signing Pedro Feliciano would miss considerable time with a shoulder injury. Burnett, 28, has an ugly 5.59 ERA in 29 innings this year, but he's held lefties to a .224/.304/.347 batting line against. He is under contract next year ($2.3MM) with a club option ($3.5MM) for 2013 ($250K buyout).
