Aldegheri will start Friday's home game against the Rays, Jeff Fletcher of The Orange County Register reports.
After the southpaw was recalled from Triple-A Salt Lake on Sunday, the Angels initially made him available out of the bullpen. Aldegheri made a one-inning, eight-pitch appearance in Monday's extra-inning loss to the Astros but hasn't worked since, so he'll be ready to step into the vacant fifth spot in the rotation. With Jack Kochanowicz (elbow) headed for season-ending Tommy John surgery, Aldegheri should have a clear path to a permanent spot if he performs well. The 24-year-old has permitted three runs on 11 hits and five walks while striking out eight batters over 12 innings at the big-league level this season but posted an unsightly 7.24 ERA, 1.72 WHIP and 32:23 K:BB across 46 frames at Triple-A.
