Contreras is expected to be the Angels' primary pitcher out of the bullpen behind starter Carson Fulmer in Sunday's game against the Mariners, Jeff Fletcher of The Orange County Register reports.
The Angels are planning to treat their final game before the All-Star break as a bullpen day, with Fulmer and Contreras likely on track to cover the bulk of the innings. Fulmer tossed three innings in relief in his last outing Monday and has covered as many as four innings in an appearance this season, so he should be able to give the Angels a decent amount of length as an opener before Contreras is likely summoned from the bullpen. Contreras had started in each of his last three appearances, tossing between two and three innings on each occasion while turning in an 8.22 ERA and 2.35 WHIP.
