the personnel for the "bullpen shuttle" have certainly changed in recent weeks. brandon woodruff is being held at colorado springs as a starter, so he apparently is no longer a bullpen candidate. were the need arise for the club to option a reliever to get a fresh arm, the obvious candidates at the moment would be corbin burnes or taylor williams, but corey knebel could be a candidate. if knebel were optioned and recalled 1 september, he would not burn his final option. the brewers relievers on the 40-man and number of remaining options (any optioned player must spend at least 10 days down unless replacing a player on the disabled list): matt albers (0; on disabled list) jacob barnes (2; optioned 13 august) corbin burnes (3) josh hader (2) ariel hernandez (2; unclear when he was optioned by the dodgers, but he has spent at least 10 days optioned between both clubs) adrian houser (1; optioned 11 august) dan jennings (0) jeremy jeffress (0) corey knebel (1) jordan lyles (0) joakim soria (0; on disabled list) jake thompson (2; optioned 2 august by the phillies; he has spent at least 10 days optioned between both clubs) aaron wilkerson (2; optioned 13 august) taylor williams (2) thus, the only relievers who are eligible to be recalled to replace a non-injured player in the coming week or so are hernandez and thompson.
