It's too late for a promotion that could end the Angels' disastrous month, but the rosters are set to increase in size nevertheless. MLB rosters expand from 26 to 28 on September 1st, in which case the Angels could carry an extra pitcher and position player.
The team has several avenues it could go down in September. Adding worthy top prospects assuredly would excite fans to no end. However, the Angels are the Angels, and they could easily bring up yet another stock reliever who fans will roll their eyes at once they see they made the roster.
