Why is my son's back shoulder dropping in his baseball swing?

Back shoulder dropping is often blamed on not getting the back shoulder "on top," but that's fixing a symptom—not the real problem. The root cause is the lead elbow inverting (flipping up/elbow up early), which forces the back shoulder down and collapses the swing. To fix it: first relax the lead elbow so it hangs naturally (no tension or lift), then focus on aggressively firing the back arm "on top." This cue exaggerates the feel to counteract the inversion—your back shoulder won't actually go way on top, but the intent corrects the lead elbow drop and keeps the back shoulder level for a connected, powerful path.

• Lead elbow inverting/up forces back shoulder to drop → weak, steep swing

• Relax lead elbow to hang naturally → stops inversion and collapse

• Cue "fire back arm on top" over-exaggerates to level shoulders and stay on plane
