O'Flaherty was mention by manager Bob Melvin as one of the guys in the closer mix with Sean Doolittle likely opening the season on the DL, reports Jane Lee of MLB.com. O'Flaherty was briefly put in the closer role in August when Doolittle missed a few weeks. O'Flaherty has put together five consecutive seasons with an ERA of 2.50 or under, but has only thrown 38 combined innings the last two seasons due to 2013 Tommy John Surgery. O'Flaherty did not have much of a platoon split in his limited 2014 innings (including an impressive career .186 batting average against to righties), but he has been much more effective in his career agaisnt lefties (.531 OPS against lefties and .714 OPS agaisnt righties) and is probably an underdog for saves to Tyler Clippard entering the spring.
