The Oakland Athletics made there Bullpen even better this off season in adding Jim Johnson and Luke Gregerson. Johnson replaces Grant Balfour as the team's closer and his been a save machine with the Baltimore Orioles the past two seasons he recorded 50 saves last year with a era of 2.94 and it's really impressive what he did in the AL East.
Luke Gregerson has been the setup man for four years for the San Diego Padres and last year he had 41 holds on the season. So Johnson and Gregerson join Ryan Cook, Sean Doolittle, Dan Otero and Fernando Abad in the bullpen. To be they have the best bullpen in the game right now and the way Bob Melvin knows how to mange a bullpen with mixing and matching this is going to be key to there season.
