re: Any drills work to eliminate a bad over the top swing?

“Reverse your loop”… I can almost guarantee you’re jerking the club to the inside on your takeaway and are probably across the line at the top. (Clubhead pointing to the right of the target line). Instead. take it back down the line or even outside, then try to make a big counterclockwise loop (assuming you’re right handed) with the clubhead. It should feel like your hands are dropping lower and closer to your body at the the start of the transition. Watch down the line videos of Sergio and Lee Trevino to see the extreme of what yours shoukd look like/what you should feel. Once you groove that, then you can try to match Rory’s takeaway and transition.
