Britt Ghiroli of MLB.com reports that the Orioles could be interested in free agent closer Chris Perez. The O's have set to the open market in search of a closer after dealing Jim Johnson to the A's, and Perez can be added to a list of possible candidates that already includes John Axford. The 28-year-old struggled in his final season in Cleveland, posting a 4.33 ERA, 1.43 WHIP and 54/21 K/BB ratio over 54 innings.
