Coming out of Spring Training, the Angels had three relievers on their roster who they thought would be capable of pitching multiple innings: Yusmeiro Petit, JC Ramirez and Bud Norris. But injuries soon forced them to reallocate those arms.
When Garrett Richards landed on the disabled list in the first week of the season, Ramirez was pressed into the starting rotation. Injuries to Huston Street, Andrew Bailey and Cam Bedrosian, meanwhile, forced Norris into the closing role. That left Petit as the Angels' primary multi-inning reliever for most of the season, a role in which he excelled.
