the brewers have talked about having flexibility in the back end of their bullpen. when you look at it, there isn't as much flexibility as one would think (assuming that no players are dfa'd). when a player is optioned, he has to spend at least 10 days optioned, unless replacing a player placed on the disabled/paternity/bereavement/restricted list. thus, someone like adrian houser, who was optioned 9 april, is off limits for an overworked bullpen. if taylor williams is optioned today for junior guerra, he's off limits for 10 days. it's conceivable that the brewers could option brett phillips for guerra, and then option guerra and recall jorge lopez (the only true reliever on the 40-man eligible to be recalled barring a disabled list move). of course, that would mean guerra is off limits for 10 days. management and fans will also have to take note of this when boone logan is ready to come off the disabled list, and again for corey knebel. relievers on the 40-man and number of remaining options: jacob barnes (2) oliver drake (0) josh hader (2) adrian houser (1) dan jennings (0) jeremy jeffress (0) j.j. hoover (0) corey knebel (1) boone logan (unclear on remaining options, but if he does have an option, he can refuse the minor league assignment, void his contract and become a free agent) jorge lopez (1) taylor williams (2)
