Otero struggled on Friday night, taking the loss after coming into a tie game in the eighth and allowing two runs. Otero is currently in the mix for the primary right-handed setup man for the A's, but has not pitched especially well so far. He has allowed runs in two of his five outings and has given up seven hits through his first four innings. Otero had an exceptional 2014, putting up a 2.28 ERA in 86.2 innings.
