A's manager Bob Melvin lists Liam Hendriks and Daniel Coulombe as relievers who could move into more prominent roles now that Sean Doolittle and Ryan Madson have been traded. Santiago Casilla has the closer role on lock down, but the A's rebuilding plan likely means Casilla will be shopped in advance of the trade deadline. One of Hendriks, Coulombe, veteran John Axford or newcomer Blake Treinen will likely take over the ninth inning duties if/when Casilla is dealt. Hendriks has an ugly 5.26 ERA on the year but a 3.33 FIP and a very nice 11.95 K/9, making him an intriguing add should he end up with the ninth inning role. Coulombe on the other hand has a 2.81 ERA and a 1.09 WHIP, but his 4.11 FIP leaves something to be desired, as does his pedestrian 7.03 K/9. Should anyone take over the ninth inning role permanently they would be worth an add in deep mixed and AL-only leagues. More than likely, manager Bob Melvin will go with a committee, making this a bullpen to stay away from in the second half.

Oakland A's reliever Daniel Coulombe has been one of the few bright spots in the Oakland bullpen this year and could be in line for an increased role, reports Susan Slusser of the San Francisco Chronicle. With relief pitcher Sean Doolittle (shoulder) on the disabled list, Coulombe is the only lefty in the bullpen. He has held lefties to a .143 batting average this season, and hitters are 1-for-16 with runners in scoring position off him. A's manager Bob Melvin acknowledged that Coulombe could see an increased role going forward. "He hasn't been in that role before, not only does he have to get comfortable with it, I have to be comfortable with it." For now, consider Coulombe a speculative add in deep formats that count holds. He should get plenty of work this week against the heavy left-handed hitting Mariners squad.
