Muller has been named the Athletics' Opening Day starter for their March 30 matchup against the Angels, Martin Gallegos of MLB.com
It wasn't even a sure thing Muller was locked into a rotation spot prior to this announcement, but the A's don't exactly have any good options for the assignment. The left-hander has been hit and miss this spring, posting a 5.65 ERA and 10:3 K:BB over 14.1 innings of work. Muller has some fantasy potential but should probably be viewed as a streaming option initially.
