Don't be surprised if you see more demotions over the next week, especially young pitching talent. At this point teams can send a player down and bring them back up after the break because they will have been down the mandatory 10 days.
Do, however, be on the lookout for fantasy managers in your league who don't take the All-Star break in to account and drop players who should only be down a couple weeks. You may be able to steal away a valuable player because of someone else's lack of attention.
