The Angels selected Dana's contract from Double-A Rocket City on Friday.
Dana will start Sunday's game against the Mariners after logging a 2.59 ERA across 135.2 innings with Rocket City this season. The 20-year-old is one of the Halos' top prospects, but he hasn't pitched above the Double-A level since joining the organization in 2022, although the organization generally avoids sending its top young arms to the hitter's paradise of Triple-A Salt Lake. If he performs well Sunday, Dana could stick in the rotation.
