Rosenberg allowed one run on two hits and two walks while striking out four batters over five innings in long relief against Toronto on Tuesday.
Angels starter Carson Fulmer was able to go just three innings, giving up five runs while tossing 75 pitches. Rosenberg -- who was recalled from Triple-A Salt Lake earlier in the day -- stepped in and logged what was essentially a starter's workload with 78 pitches of his own, and he was much more effective than Fulmer in yielding just one run across five frames. Due to the large workload, Rosenberg will presumably now be unavailable for several days, so he could move back to the minors in short order to allow Los Angeles to bring up a fresh arm.
